Loggerhead shrikes are monogamous birds. They begin breeding during their first spring. During this time, the male performs a courtship ritual that occurs in flight. He dances erratically in the air, flying rapidly up and down and occasionally chasing the female. He presents himself to his potential mate by fanning out his tail and fluttering his wings.  Females may respond to the fluttering display with begging notes, similar to those of juveniles begging for food; this encourages the male to feed her.
The bird breeds in semi-open areas in southern Ontario, Quebec, and the Canadian prairie provinces, south to Mexico. It nests in dense trees and shrubs. There is an increase in average clutch size as latitude increases. Shrikes begin incubation after laying the second to last egg, resulting in asynchronous hatching. Incubation, on average, lasts 16 days. The female lays 4 to 8 eggs in a bulky cup made of twigs and grass. Once hatched, nestlings are fed by both the male and female parent. Average fledging period is about 19 days. Young may then remain nearby and dependent on adults for 3 to 4 weeks. After that, they begin to forage independently. Oftentimes, nestlings do not survive long past hatching. In the case of dead nestlings, adult shrikes may eat or discard their bodies or else feed them to their remaining young. The oldest recorded age of a loggerhead shrike was 12 years and 6 months.


Loggerhead shrike populations have been decreasing in North America since the 1960s. Reasons behind the decline remain unclear, although suggestions include habitat loss, pesticide contamination, and human disturbance. The eastern loggerhead shrike (L.l. migrans) is critically endangered in Canada, with fewer than 35 known breeding pairs in Canada. The San Clemente Island shrike, L. l. mearnsi, is critically endangered, with a population as low as 5–10 individuals during 1983–1988. Although only this island subspecies is legally listed as endangered in the United States, the species is declining continent-wide and no longer occurs in most of the northeastern U.S. A captive population was established at the Toronto Zoo and McGill University in 1997. In 2001, an experimental field breeding and release program managed by Wildlife Preservation Canada was established. "Field breeding" refers to moving captive pairs from their wintering cages at the Toronto Zoo and McGill to large enclosures within shrike habitat in Ontario where the pairs nest and raise their young. The young then are released to the wild when they'd naturally disperse from their parents. Since 2004, over 90 young have been released annually and between 2% and 6.5% of young released have successfully migrated and returned to breed in the subsequent year.


The breeding range of the woodchat shrike is in southern Europe, northern Africa and the Middle East. The range extends from Portugal to Greece, Turkey, Iraq and Iran, and in the Arabian Peninsula including Bahrain and Kuwait, and from Mauritania and Western Sahara in northern Africa to Libya. This bird overwinters in tropical central Africa, its winter range extending from Senegal to Sudan and Ethiopia in the east and southwards to Gabon. This species often overshoots its breeding range on spring migration, and is a rare, but annual, visitor to Great Britain. The Balearic race badius has occurred in Britain around four times as a vagrant, and has also been recorded once in Ireland.


The European herring gull (Larus argentatus) is a large gull, up to 66 cm (26 in) long. One of the best-known of all gulls along the shores of Western Europe, it was once abundant. It breeds across Northern Europe, Western Europe, Central Europe, Eastern Europe, Scandinavia, and the Baltic states. Some European herring gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, e.g. in Ireland, Britain, Iceland, or on the North Sea shores. They have a varied diet, including fish, crustaceans, as well as some plants, and are also scavengers, consuming carrion and food left by or stolen from humans.
While herring gull numbers appear to have been harmed in recent years, possibly by fish population declines and competition, they have proved able to survive in human-adapted areas and can often be seen in towns acting as scavengers.


L. a. argentatus – Pontoppidan, 1763, the nominate form, sometimes known as the Scandinavian herring gull, breeds in Scandinavia and northwestern Russia. Northern and eastern populations migrate southwest in winter. It is a large, bulky gull with extensive white in the wingtips. The outermost primary, p10 often has a large white spot (called a mirror) that extends to the wingtip. The bill is longer and forehead flatter than argenteus.
L. a. argenteus – Brehm & Schilling, 1822, sometimes known as the Western European herring gull breeds in Western Europe in Iceland, the Faroes, Britain, Ireland, France, Belgium, the Netherlands and Germany. Many birds are resident while others make short-distance migratory journeys. It is smaller than L. a. argentatus with more black and less white in the wingtips (p10 mirror is distinct from the white wingtip spot) and paler upper parts.
These taxa are classified as subspecies of Larus argentatus by some authorities such as the American Ornithologists' Union and Handbook of the Birds of the World. Others such as the Association of European Rarities Committees, British Ornithologists' Union, and the International Ornithological Union now regard them as one or two separate species.
L. (a.) smithsonianus, the American herring gull, breeds in Alaska, Canada, and the Northeast United States. Many birds migrate southwards in winter, reaching as far as Central America and the West Indies. Immature birds tend to be darker and more uniformly brown than European herring gulls and have a dark tail.
L. (a.) vegae, the Vega gull, breeds in northeastern Siberia. It winters in Japan, Korea, eastern China, and Taiwan.
Several other gulls have been included in this species in the past, but are now normally considered separate, e.g. the yellow-legged gull (L. michahellis), the Caspian gull (L. cachinnans), the Armenian gull (L. armenicus) and Heuglin's gull (L. heuglini).


When forming a pair bond, the hen approaches the cock on his territory with a hunched, submissive posture, while making begging calls (similar to those emitted by young gulls). If the cock chooses not to attack her and drive her away, he responds by assuming an upright posture and making a mewing call. This is followed by a period of synchronised head-tossing movements, after which the cock then regurgitates some food for his prospective mate. If this is accepted, copulation follows. A nesting site is then chosen by both birds which is returned to in successive years. European herring gulls are almost exclusively sexually monogamous and may pair up for life, provided the couple is successful in hatching their eggs.
Two to four eggs, usually three, are laid on the ground or cliff ledges in colonies, and are defended vigorously by this large gull. The eggs are usually olive-brown in colour with dark speckles or blotches. They are incubated by both parents for 28–30 days. The chicks hatch with their eyes open, covered with fluffy down, and they are able to walk around within hours. Breeding colonies are preyed upon by great black-backed gulls, harriers, corvids and herons.
Juveniles use their beaks to peck at the red spot on the beaks of adults to indicate hunger. Parents then typically disgorge food for their offspring. The young birds are able to fly 35–40 days after hatching and fledge at five or six weeks of age. Chicks are generally fed by their parents until they are 11–12 weeks old, but the feeding may continue for more than six months of age if the young gulls continue to beg. The male feeds the chick more often than the female before fledging, with the female more often feeding after fledging.
Like most gulls, European herring gulls are long-lived, with a maximum age of 49 years recorded. Raptors (especially owls, peregrine falcons, and gyrfalcons) and seals (especially grey seals) occasionally prey on the non-nesting adults.


The Caspian gull breeds around the Black and Caspian Seas, extending eastwards across Central Asia to north-west China. In Europe, it has been spreading north and west and now breeds in Poland and eastern Germany. Some birds migrate south as far as the Red Sea and Persian Gulf, while others disperse into Western Europe, in countries such as Sweden, Norway and Denmark or the Benelux and even North of France. Small numbers are now seen regularly in Britain, especially in South-east England, East Anglia, and the Midlands.


The species is resident to coastlines of the East China Sea, Japan, Manchuria and the Kuril Islands. It is a vagrant to Alaska and North America and has been found in the Philippines.


The species is common on the shoreline of Korea and on various islands. There are over 20,000 black-tailed gulls on Liancourt Rocks, and numbers are increasing due to the absence of predators. In 2008, the bird was officially chosen as one of the mascots of Liancourt Rocks. Nando and Hongdo islands, both Korean natural monuments as of 1982, are also known breeding grounds.


The glaucous-winged gull is rarely found far from the ocean. It is a resident from the western coast of Alaska to the coast of Washington. These glaucous winged gulls can also be found in the Puget Sound region. It also breeds on the northwest coast of Alaska, in the summertime and in the Russian Far East.  During winter, they can be found along the coast of California, Oregon, Baja California, Baja California Sur, and Sonora.  Glaucous-winged gulls are thought to live about 15 years, but some live much longer; a bird in British Columbia, for example, lived for more than 21 years, while one in the US state of Washington lived for at least 22 years, 9 months. The longevity record though, is more than 37 years, for a bird banded as a chick in British Columbia.
It is an exceptionally rare vagrant to the Western Palearctic region, with records from Morocco, the Canary Islands and, most recently, from Ireland in February and March 2016. It has also been recorded in Britain in the winters of 2006/2007 and 2008/2009. The 2008/2009 record was from Saltholme Pools, Cleveland, and attracted hundreds of twitchers.


The Iceland gull (Larus glaucoides) is a medium-sized gull that breeds in the Arctic regions of Canada and Greenland, but not in Iceland (as its name suggests), where it is only seen during winter. The genus name is from Latin larus, which appears to have referred to a gull or other large seabird. The specific name glaucoides denotes its resemblance to Larus glaucus, a synonym of Larus hyperboreus, the glaucous gull; -oides is Ancient Greek and means "resembling".


This species can be found breeding in coastal areas from the extreme northwest portion of Russia, through much of coastal Scandinavia, on the Baltic Sea coasts, to the coasts of northwestern France, the United Kingdom and Ireland. Across the northern portion of the Atlantic, this gull is distributed in Iceland, the Faroe Islands, southern Greenland and on the Atlantic coasts of Canada and the United States. Though formerly mainly just a non-breeding visitor south of Canada in North America, the species has spread to include several colonies in the New England states and now breeds as far south as North Carolina. Individuals breeding in harsher environments will migrate south, wintering on northern coasts of Europe from the Baltic Sea to southern Portugal, and regularly down to coastal Florida in North America. During the winter in the Baltic Sea, the bird usually stays close to the ice boundary. North of the Åland islands, the sea often freezes all the way from Sweden to Finland, and then the bird migrates to open waters. Exceptionally, the species can range as far south as the Caribbean and off the coast of northern South America.
The great black-backed gull is found in a variety of coastal habitats, including rocky and sandy coasts and estuaries, as well as inland wetland habitats, such as lakes, ponds, rivers, wet fields and moorland. They are generally found within striking distance of large bodies of water while ranging inland. Today, it is a common fixture at refuse dumps both along coasts and relatively far inland. The species also makes extensive use of dredge spoils, which, in the state of New Jersey, are their most prevalent nesting sites. It generally breeds in areas free of or largely inaccessible to terrestrial predators, such as vegetated islands, sand dunes, flat-topped stacks, building roofs and sometimes amongst bushes on salt marsh islands. During the winter, the great black-backed gull often travels far out to sea to feed.


It is now generally accepted that the yellow-legged gull is a full species, but until recently there was much disagreement. For example, British Birds magazine split the yellow-legged gull from the herring gull in 1993 but included the Caspian gull in the former, but the BOU in Great Britain retained the yellow-legged gull as a subspecies of the herring gull until 2007. DNA research, however, suggests that the yellow-legged gull is actually closest to the great black-backed gull L. marinus and the Armenian gull L. armenicus, while the Caspian gull is closer to the herring gull and the lesser black-backed gull L. fuscus, rather than being each other's closest relatives.
There are two subspecies of the yellow-legged gull:
L. m. michahellis Naumann, 1840: nominate, found in western and southern Europe, northwestern Africa, and the Mediterranean.
L. m. atlantis (Dwight, 1922), syn. Larus fuscus atlantis, Dwight, 1922: found in Macaronesia (the Canary Islands, Madeira, the Azores). This subspecies is also sometimes known as the Atlantic gull and is potentially a full species in its own right. Birds breeding on the Atlantic coasts of Morocco, Portugal and Galicia (and spreading north from there) are usually also included here, but are sometimes considered to be a third subspecies, L. m. lusitanius. Atlantic Ocean birds have darker wings and back in comparison with Mediterranean birds, creating a more pronounced contrast to the white parts.


The breeding range is centred on the Mediterranean Sea. In North Africa, it is common in Morocco, Algeria and Tunisia and increasing in places. Recent breeding has occurred in Libya and Egypt. In the Middle East, a few breed in Israel and Syria with larger numbers in Cyprus and Turkey. In Europe, there are colonies all along the Mediterranean coast, and also on the Atlantic islands and coasts north to Brittany and west to the Azores. It also breeds on the western side of the Black Sea; here it overlaps with the Caspian gull but there is a difference in habitat, with the yellow-legged gull preferring sea cliffs and the Caspian gull flatter shores. In recent decades birds have spread north into central and western Europe. One to four pairs have attempted to breed in southern England since 1995 (sometimes hybrid pairs with lesser black-backed gulls), though colonisation has been very slow.
Many birds remain in the same area all year round, but others migrate to spend the winter in mild areas of western Europe or head south as far as Senegal, Gambia and the Red Sea. There is also extensive northward post-breeding dispersal in the late summer, with numbers in southern England high from July to October. It is reported as a vagrant to northeastern North America and Nigeria.


The western gull is a year-round resident in California, Oregon, Baja California, and southern Washington. It is migratory, moving to northern Washington, British Columbia, and Baja California Sur to spend the nonbreeding season.


Common toothwort is widely distributed throughout Europe, its range extending from France and Norway to Russia, Bulgaria, Italy and Greece. In the British Isles, it is found in  England and Northern Ireland, and less often in lowland areas of East England, Southwest England, Wales, Scotland and the Republic of Ireland. Its natural habitats are deciduous woodland, hedgerows and the banks of rivers and streams. It grows in Hatherton Flush, an SSSI in Cheshire.


The narrow-leaved everlasting-pea is native to parts of Africa, Europe and Asia. Its natural habitat is forest edges, sparse broad-leaved hillside forests, dry hillside meadows, hedgerows, embankments and waste ground. It uses its tendrils to scramble over plants, shrubs and the lower branches of trees.


The redback spider is widespread across Australia. The current distribution reported by the World Spider Catalogue includes Southeast Asia and New Zealand. Colonies and individuals have been found elsewhere, including Japan, England, Belgium, the United Arab Emirates and Iran. It was believed at one time that the redback may have been introduced to Australia, because when it was first formally described in 1870, it appeared to be concentrated around sea ports. However, an earlier informal description (1850) from the Adelaide Hills is now known, and names in Australian Aboriginal languages also show that it was present well before European settlement. Its original range is thought to be a relatively small arid part of South Australia and Western Australia. Its spread has been inadvertently aided by modern buildings, which often provide habitats conducive to redback populations. The close relationship between the redback and the New Zealand katipō also supports the native status of both in their respective countries.
Outside urban areas, the redback is more often found in drier habitats ranging from sclerophyll forest to desert, even as harsh as the Simpson Desert. It became much more common in urban areas in the early decades of the 20th century, and is now found in all but the most inhospitable environments in Australia and its cities. It is particularly common in Brisbane, Perth and Alice Springs. It is wide spread throughout urban Australia, with most suburban backyards in the city of Canberra (for instance) having one or more nesting females in such places as firewood piles, stored brick stacks and around unused or restoring motor vehicles as well as generally behind the shed - as observed since at least the 1970s and probably earlier. The redback spider is commonly found in close proximity to human residences. Webs are usually built in dry, dark, sheltered sites, such as among rocks, in logs, tree hollows, shrubs, old tyres, sheds, outhouses, empty tins and boxes, children's toys or under rubbish or litter. Letterboxes and the undersurface of toilet seats are common sites. Populations can be controlled by clearing these habitats, squashing the spiders and their egg sacs, and using pesticide in outhouses. The CSIRO Division of Entomology recommends against the use of spider pesticides due to their toxicity, and because redbacks are rapid recolonists anyway.
Spiders in the French territory of New Caledonia in the Pacific were identified as L. hasselti in 1920, based on morphology. Their behaviour differs from Australian redbacks, as they do not engage in sexual cannibalism and are less prone to biting humans. The first recorded envenomation in New Caledonia was in 2007.


The black house spider (Badumna insignis), the cellar spider (Pholcus phalangioides) and the giant daddy-long-legs spider (Artema atlanta) are known to prey on the redback spider, and redbacks are often absent if these species are present in significant numbers.  Agenioideus nigricornis, a spider wasp, is a parasitoid of the adult redback. Other wasps of the families Eurytomidae and Ichneumonidae parasitise redback eggs, and mantid lacewings (Neuroptera and Mantispidae) prey on redback eggs.


The southern widow is primarily found in (and is indigenous to) the southeastern United States, ranging as far north as Ohio and as far west as Texas. The northern black widow (L. variolus) is found primarily in the northeastern United States and southeastern Canada, though its range overlaps with that of L. mactans. (In Canada, northern black widows occur in the southern parts of British Columbia, Alberta, Saskatchewan, Manitoba, and Quebec.) In the Dominican Republic L. mactans is found throughout the whole country.
Latrodectus mactans, along with Latrodectus hesperus and Latrodectus geometricus (the "brown widow spider"), is established in the Hawaiian Islands (USA). One pathway of entry into Hawaii for at least one of these black widow species is imported produce (which is also considered an important potential pathway for widow spiders elsewhere).


The Tennessee warbler breeds from the Adirondack Mountains in New York through northern Vermont, New Hampshire, and Maine north and west throughout much of Canada. It is also found breeding in northeast Minnesota and northern Upper Peninsula of Michigan. It is migratory, wintering in southern Central America, the Caribbean, and northern Colombia and Venezuela, with a few stragglers going as far south as Ecuador. It is a very rare vagrant to western Europe. This bird was named from a specimen collected in Tennessee, where it may appear during migration.


The Nashville warbler is a small warbler. Both male and female Nashville warblers have a gray head fading into a greenish back and wings, a white belly and a yellow throat and breast. They have a complete white eye ring, no wing bars, and a thin pointed black bill. Adult males have a rusty brown patch on their crown, which is usually hard to see and often covered by gray feathers. Males will raise it slightly when agitated. Females and immature birds have a duller olive-grey head, and less bold yellow on their throat. The Nashville warbler is closely related to Virginia's warbler, Lucy's warbler, and the Colima warbler, the four sharing generally similar plumage.
Measurements:
Length: 4.3–5.1 in (11–13 cm)
Weight: 0.2–0.5 oz (5.7–14.2 g)
Wingspan: 6.7–7.9 in (17–20 cm)


Nashville warblers breed in two distinct areas, one in Canada and the northeastern United States, and another in the western United States. The northeastern part of its range extends from Côte-Nord and Cape Breton Island in eastern Canada to central Alberta. For the most part, it only breeds between about 52 and 45.5 degrees north, but it is also found less commonly in the Appalachians of Pennsylvania and West Virginia. Although named after Nashville, Tennessee, the Nashville warbler only visits that area during migration. They migrate to southernmost Texas and California, mid-Mexico, and the northernmost parts of Central America (Guatemala and El Salvador) in winter. In their breeding range, they prefer open mixed woods and bog habitats.


Lema daturaphila, commonly known as the three-lined potato beetle, is a species of beetle in the family Chrysomelidae. It is originally from Central and North America, but has spread elsewhere.


The narrow-billed woodcreeper (Lepidocolaptes angustirostris) is a species of bird in the Dendrocolaptinae subfamily. It is found in Argentina, Bolivia, Brazil, Paraguay, Suriname, and Uruguay. Its natural habitats are subtropical or tropical dry forests and dry savanna. As all members of its subfamily, it is a creeping bird which lives on small arthropods and vertebrates it catches under the bark of trees. The woodcreeper nests in cavities, both natural and bird-(e.g. woodpecker)made. It lays two to three white eggs, brooded jointly by the pair.


Fossils of the genus dating from 100 million years ago (Mya) have been found in Africa, Asia, Europe, North America, and South America. In the US, fossils of the modern species date back to the Pleistocene, where they were discovered in the Kingsdown Formation in Meade County, KS and date back to the Irvingtonian (1.8 - 0.3 Mya). Longnose gar are found in Central America, Cuba, North America, and the Isla de la Juventud.
Longnose gar are frequently found in fresh water in the eastern half of the United States, but some gar were found in salinities up to 31 ppt. Their microhabitats consist of areas near downed trees, stone outcrops, and vegetation.


Currently, no management of this species is being conducted, nor is it federally listed as endangered, although some states have reported it as threatened (South Dakota, Delaware, and Pennsylvania). In the early 1900s, longnose gar were considered as destructive predators. Soon after this characterization, gar population reduction methods were established. Their declining populations are due to overfishing, habitat loss, dams, road construction, pollution, and other human-caused destruction of the aquatic systems. Because of their long lifespans and older sexual maturity age, factors affecting their reproduction is an issue in preserving them. Overfishing is a large issue for this fish, especially when the fish have not reached sexual maturity due to the female not reaching sexual maturity until about 6 years of age.


The Florida gar (Lepisosteus platyrhincus) is a species of gar found in the US from the Savannah River and Ochlockonee River watersheds of Georgia and throughout peninsular Florida. Florida gar can reach a length over 3 ft (91 cm). The young feed on zooplankton and insect larvae, as well as small fish. Adults mainly eat fish, shrimp, and crayfish. Although edible, they are not popular as food. The roe is highly toxic to many animals, including humans and birds.


The pumpkinseed's natural range in North America is from New Brunswick down the east coast to South Carolina.  It then runs inland to the middle of North America, and extends through Iowa and back through Pennsylvania.
Pumpkinseed sunfish have however been introduced throughout most of North America. They can now be found from Washington and Oregon on the Pacific Coast to Georgia on the Atlantic Coast. Yet they are primarily found in the northeastern United States and more rarely in the south-central or southwestern region of the continent.
In Europe, the pumpkinseed is considered an invasive species. They were introduced to European waters, and could outcompete native fish. This species is included since 2019 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.


Longear sunfish are found in North America, primarily in the Mississippi and Great Lakes regions. Longear sunfish are mostly found in freshwater areas west of the Appalachian Mountains. Some Lepomis populations are located as far north and west as southern Quebec and Minnesota. The species has also been spotted in places as far south and west as central Mexico and New Mexico. The native territory of the longear sunfish is exclusive to the North American Continent. It is found primarily in the Mississippi and Great Lakes watersheds. The longear sunfish is restricted in range to certain large streams. This species can be located in the St. Lawrence and Great Lakes, Hudson Bay, and Mississippi River. The species has been introduced to stream ecosystems along the eastern coast of the United States. The distribution of the longear sunfish throughout North America has not been affected since the species has been followed. This may be due to the species' ability to travel throughout large bodies of water, thus avoiding dams and man-made interferences along smaller streams. They are also able to occupy different body of water types, thus making them more resilient to a decrease in their range distribution.


Longear sunfish are not currently endangered in any of their native habitats. They are not listed federally or internationally as threatened or endangered, but efforts are still being conducted in order to protect the species. Small conservation actions are taking place all over the US. Control of non-point source pollution from urbanization and agricultural practices is needed for this species, which is intolerant of turbidity. Habitat degradation and loss from shoreline and watershed agriculture threatens this species which prefers clear, shallow streams with aquatic vegetation. Sedimentation and agricultural runoff also threatens this species which is believed to have been lost from many locations because of the effects of soil erosion. The longear sunfish is not in danger of overfishing, because it is not considered a sport fish, and because the sunfish is not especially good for eating. The longear sunfish is currently threatened in states such as Wisconsin and New York. Refuge areas in these two states are being created along lakes and streams in order to protect the few, disjunct locations where this species live. Since this species has a fairly large distribution nationally and its abundance is still quite high, there are not many conservation groups taking serious action in preserving this species. The longear sunfish tends to do well in rivers and streams that do not undergo much disturbance. If man-made disturbances continue to disrupt shorelines then agencies may begin to see an increased reduction in the Lepomis megalotis abundance nationwide.


Redear sunfish are native to the Southeast U.S.  They range from North Carolina to Florida, west to southern Illinois and Missouri, and south to the Rio Grande drainage in Texas. However, this fish has also been widely introduced to other locations in the United States outside of its native range.
In the wild, the redear sunfish inhabits warm, quiet waters of lakes, ponds, streams, and reservoirs. They prefer to be near logs and vegetation, and tend to congregate in groups around these features. This sunfish is also located in many freshwater marsh wetlands.


At least 13 insect genera, three spider families, one phalangid (Opiliones), and one mite have been recorded as either generalist or specialized predators of the varying stages of L. decemlineata. These include the ground beetle Lebia grandis, the coccinellid beetles Coleomegilla maculata and Hippodamia convergens, the shield bugs Perillus bioculatus and Podisus maculiventris,  various species of the lacewing genus Chrysopa, the wasp genus Polistes, and the damsel bug genus Nabis.
The predatory ground beetle L. grandis is a predator of both the eggs and larvae of L. decemlineata, and its larvae are parasitoids of the pupae. An adult L. grandis may consume up to 23 eggs or 3.3 larvae in a single day.
In a laboratory experiment, Podisus maculiventris was used as a predatory threat to female L. decemlineata specimens, resulting in the production of unviable trophic eggs alongside viable ones; this response to a predator ensured that additional food was available for newly hatched offspring to increase their survival rate. The same experiment also demonstrated the cannibalism of unhatched eggs by newly hatched L. decemlineata larvae as an antipredator response.


The purple-rumped sunbird is a common resident breeder in southern India, Sri Lanka and Bangladesh. It is found in Gujarat to the west (possibly a recent expansion) and extending into Assam (Hailakandi) or Meghalaya in the east. Records from Myanmar are not certain. This species is found in a variety of habitats with trees, including scrub and cultivation and is usually absent from dense forest.


Leptograpsus variegatus is an omnivore and will eat a broad range of plant and animal life. While the crab may eat algae growing on rocks (such as Corallina and Ulva lactuca), they have also been observed feeding on barnacles and limpets. The crab captures limpets by quickly placing their chelae under the limpets shell when it begins to move and then flips it over. Notably, there is also a single observation of this species preying upon a Raukawa gecko, which is native to New Zealand.


Central America: Belize, Costa Rica, El Salvador, Guatemala, Honduras, southern Mexico, Nicaragua, Panama.
South America: Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Paraguay, Peru, Trinidad and Tobago, Uruguay, Venezuela.


Leptophobia aripa, the common green-eyed white or mountain white, is a butterfly in the family Pieridae. It is native to Mexico, Central America and South America, but strays may be found as far north as southern Texas.
It is a multivoltine species with overlapping generations. Adults feed on flower nectar of various species, including Emilia sonchifolia, Lantana camara and Bidens pilosa.
The larvae feed on Brassicaceae species, including Brassica oleracea. Other records include Nasturtium officinale, Tovaria pendula and Tropaeolum moritzianum.


The speckled bush-cricket is common across much of Europe. It ranges from the British Isles, France, Poland and Belgium in the west to the European parts of Russia in the east, and from southern Scandinavia in the north to southern Italy, Bulgaria and Greece. It has been recorded as far south as Israel. It is also present in the Nearctic realm.


Leptotes cassius, the Cassius blue or tropical striped blue, is a butterfly of the family Lycaenidae. It is found in North America in Florida including the Keys, Texas south through the Caribbean, Mexico, and Central America to South America. Strays have been found in New Mexico, Kansas, Missouri, South Carolina, North Carolina and Virginia.
The wingspan is 20–35 mm.
The butterfly species has an important role in Marisha Pessl's 2006 novel Special Topics in Calamity Physics. The protagonist, Blue van Meer, is named in honor of the Cassius blue.
The caterpillars feed natively on Fabaceae. Food plants on record are Amorpha crenulata, woolly rattlepod (Crotalaria incana), Galactia regularis and lima bean (Phaseolus lunatus). It can also successfully develop feeding on Cape leadwort (Plumbago auriculata) or doctorbush (P. scandens), which (among the eudicots) are not closely related to its usual food plants.


The following subspecies have been identified:
Leptotes pirithous pirithous (southern Europe, Caucasus, Transcaucasia, North Africa)
Leptotes pirithous capverti Libert, Baliteau & Baliteau, 2011 (island of Santo Antão, Cape Verde)
Leptotes pirithous insulanus (Aurivillius, 1924) (Mozambique Channel)


The white-tipped dove (Leptotila verreauxi) is a large New World tropical dove. Its scientific name commemorates the French naturalists Jules and Edouard Verreaux.


The dove is a resident breeder from southernmost Texas in the United States through Mexico and Central America south to western Peru and central Argentina. It also breeds on the offshore islands of northern South America, including Trinidad and Tobago and the Netherlands Antilles. It inhabits scrub, woodland and forest.


The dove is about 28 cm (11 in) long and weighs 155 g (5.5 oz). Adult birds of most races have a grey tinge from the crown to the nape, a pale grey or whitish forehead and a whitish throat. The eye-ring is typically red in most of its range, but blue in most of the Amazon and northern South America. The upperparts and wings are grey-brown, and the underparts are whitish shading to pinkish, dull grey or buff on the chest. The underwing coverts are rufous. The tail is broadly tipped with white, but this is best visible from below or in flight. The bill is black, the legs are red and the iris is yellow.
The white-tipped dove resembles the closely related grey-fronted dove (Leptotila rufaxilla), which prefers humid forest habitats. The best distinctions are the greyer forehead and crown, which contrast less with the hindcrown than in the grey-fronted dove. In the area of overlap, the white-tipped dove usually has a blue (not red) eye-ring, but this is not reliable in some parts of Brazil, Argentina, Bolivia, Paraguay and Uruguay, where it typically is red in both species.


Northern populations of snowshoe hares undergo cycles that range from seven to 17 years between population peaks. The average time between peaks is approximately 10 years. The period of abundance usually lasts for two to five years, followed by a population decline to lower numbers or local scarcity. Areas of great abundance tend to be scattered. Populations do not peak simultaneously in all areas, although a great deal of synchronicity occurs in northern latitudes. From 1931 to 1948, the cycle was synchronized within one or two years over most of Canada and Alaska, despite differences in predators and food supplies. In central Alberta, low snowshoe hare density occurred in 1965, with 42 to 74 snowshoe hares per 100 acres (40 ha). The population peak occurred in November 1970 with 2,830 to 5,660 snowshoe hares per 100 acres (40 ha). In the southern parts of its range, snowshoe hare populations do not fluctuate radically.
Exclosure experiments in Alberta indicated browsing by snowshoe hares during population peaks has the greatest impact on palatable species, thus further reducing the amount of available foods. In this study, insufficient nutritious young browse was available to sustain the number of snowshoe hares present in the peak years (1971 and 1972) in winter.
The hare's fluctuating numbers are modelled by the Lotka–Volterra equations.


Major variables in habitat quality include average visual obstruction and browse biomass. Snowshoe hares prefer young forests with abundant understories. The presence of cover is the primary determinant of habitat quality, and is more significant than food availability or species composition. Species composition does, however, influence population density; dense softwood understories support greater snowshoe hare density than hardwoods because of cover quality. In Maine, female snowshoe hares were observed to be more common on sites with less cover but more nutritious forage; males tended to be found on sites with heavier cover.
Winter browse availability depends on height of understory brush and winter snow depth; 6-to-8-foot-tall (1.8 to 2.4 m) saplings with narrow stem diameters are required for winter browse in heavy snow.
In northern regions, snowshoe hares occupy conifer and mixed forests in all stages of succession, but early successional forests foster peak abundance. Deciduous forests are usually occupied only in early stages of succession. In New England, snowshoe hares preferred second-growth deciduous, coniferous, and mixed woods with dense brushy understories; they appear to prefer shrubby old-field areas, early- to mid-successional burns, shrub-swamps, bogs, and upper montane krumholz vegetation. In Maine, snowshoe hares were more active in clearcut areas than in partially cut or uncut areas. Sapling densities were highest on 12- to 15-year-old plots; these plots were used more than younger stands. In northern Utah, they occupied all the later stages of succession on quaking aspen and spruce-fir, but were not observed in meadows. In Alberta, snowshoe hares use upland shrub-sapling stages of regenerating aspens (either postfire or postharvest). In British Columbia overstocked juvenile lodgepole pine (Pinus contorta) stands formed optimal snowshoe hare habitat.
In western Washington, most unburned, burned, or scarified clearcuts will normally be fully occupied by snowshoe hares within four to five years, as vegetation becomes dense. In older stands (more than 25 years), stem density begins to decline and cover for snowshoe hares decreases. However, in north-central Washington, they may not
colonize clearcuts until six or seven years, and it may take 20 to 25 years for their density to reach maximum. Winter snowshoe hare pellet counts were highest in 20-year-old lodgepole pine stands, lower in older lodgepole stands, and lowest in spruce-dominated stands. In western Oregon, snowshoe hares were abundant only in early successional stages, including stable brushfields. In west-central Oregon, an old-growth Douglas-fir forest was clearcut and monitored through 10 years of succession. A few snowshoe hares were noted in adjacent virgin forest plots; they represented widely scattered, sparse populations. One snowshoe hare was observed on the disturbed plot 2.5 years after it had been clearcut and burned; at this stage, ground cover was similar to that of the uncut forest. By 9 years after disturbance, snowshoe hare density had increased markedly.
In western Washington, snowshoe hares routinely used steep slopes where cover was adequate; most studies, however, suggest they tend to prefer gentle slopes. Moonlight increases snowshoe hare vulnerability to predation, particularly in winter. They tend to avoid open areas during bright phases of the moon and during bright periods of a single night. Their activity usually shifts from coniferous understories in winter to hardwood understories in summer.
Vegetative structure plays an important role in the size of snowshoe hare home ranges. Snowshoe hares wander up to 5 miles (8 km) when food is scarce. In Montana home ranges are smaller in brushy woods than in open woods. In Colorado and Utah, the average home range of both sexes was 20 acres (8.1 ha). On the Island of Montreal in Quebec, the average daily range for both sexes was 4 acres (1.6 ha) in old-field mixed woods. In Montana, the home range averaged 25 acres (10 ha) for males and 19 acres (7.6 ha) for females. In Oregon the average snowshoe hare home range was 14.6 acres (5.9 ha).


Like other jackrabbits, the black-tailed jackrabbit has distinctive long ears, and the long powerful rear legs characteristic of hares. Reaching a length about 2 ft (61 cm), and a weight from 3 to 6 lb (1.4 to 2.7 kg), the black-tailed jackrabbit is the third-largest North American jackrabbit, after the antelope jackrabbit and the white-tailed jackrabbit. Additionally, the much more northerly Arctic hare and Alaskan hare are somewhat larger than the jackrabbit members of the hare genus. The black-tailed jackrabbit's dorsal fur is agouti (dark buff peppered with black), and its undersides and the insides of its legs are creamy white. The ears are black-tipped on the outer surfaces, and unpigmented inside. The ventral surface of the tail is grey to white, and the black dorsal surface of the tail continues up the spine for a few inches to form a short, black stripe. The females are larger than males, with no other significant differences.


Although 17 subspecies are recognized, this number may be excessive. Using cluster analysis of anatomical characters, Dixon and others found that black-tailed jackrabbit subspecies separated into two distinct groups that are geographically separated west and east of the Colorado Rocky Mountains and the Colorado River. They suggested only two infrataxa are warranted: the western subspecies L. c. californicus and the eastern subspecies L. c. texianus.
The black-tailed jackrabbit is the most widely distributed jackrabbit (Lepus species) in North America. Native black-tailed jackrabbit populations occur from central Washington east to Missouri and south to Baja California Sur and Zacatecas. Black-tailed jackrabbit distribution is currently expanding eastward in the Great Plains at the expense of white-tailed jackrabbit. The black-tailed jackrabbit has been successfully introduced in southern Florida and along the coastline in Maryland, New Jersey, and Virginia.
Six subspecies of L. californicus are in the Baja California Peninsula, three of which are endemic to the surrounding islands. The current distribution is a result of sea-level rise about 21,000 years ago, after the last glacial maximum. Due to this geographic isolation, the current subspecies of L. californicus living on the peninsula can be separated into three subclades based on similar DNA structure and pelage color. The first clade is associated with subspecies L. c. xanti, and contains all subspecies found in the southernmost part of the Baja Peninsula; it has a yellowish color pattern. The second clade is associated with subspecies L. c. magdalenae, and includes all subspecies found between the La Paz isthmus and the southern Vixcaino Desert, including subspecies L. c. xanti, L. c. sheldoni, and L. c. martirensis. This clade has a coloration pattern range of light brown to yellow. The third clade is associated with subspecies L. c. martirensis, and includes all subspecies found from the Viscaino Desert to the northernmost part of the peninsula.
Distribution of subspecies occurring entirely or partially in the United States is:
L. c. altamirae (Nelson)
L. c. asellus (G. S. Miller)
L. c. bennettii (Gray) – coastal southern California to Baja California Norte
L. c. californicus (Gray) – coastal Oregon to coastal and Central Valley California
L. c. curti (E. R. Hall)
L. c. deserticola (Mearns) – southern Idaho to Sonora
L. c. ememicus (J. A. Allen) – central Arizona to Sonora
L. c. festinus (Nelson)
L. c. magdalenae (Nelson)
L. c. martirensis (J. M. Stowell)
L. c. melanotis (Mearns) – South Dakota to Iowa, Missouri, and central Texas
L. c. merriamai (Mearns) – south-central and southeastern Texas to Tamaulipas
L. c. richardsonii (Bachman) – central California
L. c. sheldoni (W. H. Burt)
L. c. texianus (Waterhouse) – southeastern Utah and southwestern Colorado to Zacatecas
L. c. wallawalla (Merriam) – eastern Washington to northeastern California and northwestern Nevada
L. c. xanti (Thomas)


Male black-tailed jackrabbits reach sexual maturity around 7 months of age. Females usually breed in the spring of their second year, although females born in spring or early summer may breed in their first year. Ovulation is induced by copulation. The breeding season is variable depending upon latitude and environmental factors. In the northern part of their range in Idaho, black-tailed jackrabbits breed from February through May. In Utah, they breed from January through July, with over 75% of females pregnant by April. The Kansas breeding season extends from January to August. Breeding in warm climates continues nearly year-round. Two peak breeding seasons corresponding to rainfall patterns and growth of young vegetation occur in California, Arizona, and New Mexico. In Arizona, for example, breeding peaks during winter (January–March) rains and again during June monsoons.
The gestation period ranges from 41 to 47 days. More litters are born in warm climates: the number of litters born each year ranges from two per year in Idaho to seven in Arizona. Litter sizes are largest in the northern portions of black-tailed jackrabbit's range and decrease toward the south. Average litter size has been reported at 4.9 in Idaho, 3.8 in Utah, and 2.2 in Arizona.
Female black-tailed jackrabbits do not prepare an elaborate nest. They give birth in shallow excavations called forms that are no more than a few centimeters deep. Females may line forms with hair prior to giving birth, but some drop litters in existing depressions on the ground with no further preparation. Young are born fully furred with eyes open, and are mobile within minutes of birth. Females do not protect or even stay with the young except during nursing. Ages of weaning and dispersal are unclear since the young are well camouflaged and rarely observed in the field. Captive black-tailed jackrabbits are fully weaned by 8 weeks. The young stay together for at least a week after leaving the form.


In Great Basin, big sagebrush is a primary forage species and is used throughout the year; in southern Idaho it forms 16–21% of the
black-tailed jackrabbit summer diet. Rabbitbrush (Chrysothamnus spp.), spiny hopsage (gray spinosa), and black greasewood are also browsed. Four-wing saltbush (Atriplex canescens) is heavily used in western Nevada. In Butte County, Idaho, winterfat comprises 41% of black-tailed jackrabbits' annual diet. Grasses comprise 14% of the diet, with most grass consumption in March and April. Russian thistle (Salsola kali) is an important forb diet item. Needle-and-thread grass (Stipa comata) and Indian ricegrass (Oryzopsis hymenoides) are preferred grasses. Other preferred native grasses include Sandberg bluegrass (Poa secunda) and bluebunch wheatgrass (Pseudoroegneria spicata). Where available, crested wheatgrass (Agropyron desertorum and Agropyron cristatum) and barley (Hordeum vulgare) are highly preferred. Cheatgrass (Bromus tectorum) use is variable: it comprises 45% of the April diet on two southern Idaho sites, but black-tailed jackrabbit on an eastern Washington site do not use it.


The black-tailed jackrabbit plays host to many ectoparasites including fleas, ticks, lice, and mites, and many endoparasites including trematodes, cestodes, nematodes, and botfly (Cuterebra) larvae. Diseases affecting the black-tailed jackrabbit in the West are tularemia, equine encephalitis, brucellosis, Q fever, and Rocky Mountain spotted fever. Ticks are vectors for tularemia, and infected ticks have been found on jackrabbits in the West. Jackrabbits infected with tularemia die very quickly.
The high prevalence of disease and parasites in wild jackrabbits affects human predation. Many hunters will not collect the jackrabbits they shoot, and those who do are well-advised to wear gloves while handling carcasses and to cook the meat thoroughly to avoid contracting tularemia. Most hunting of jackrabbits is done for pest control or sport.


European hares are large leporids and adults can only be tackled by large predators such as canids, felids and the largest birds of prey. In Poland it was found that the consumption of hares by foxes was at its highest during spring, when the availability of small animal prey was low; at this time of year, hares may constitute up to 50% of the biomass eaten by foxes, with 50% of the mortality of adult hares being caused by their predation. In Scandinavia, a natural epizootic of sarcoptic mange which reduced the population of red foxes dramatically, resulted in an increase in the number of European hares, which returned to previous levels when the numbers of foxes subsequently increased. The golden eagle preys on the European hare in the Alps, the Carpathians, the Apennines and northern Spain. In North America, foxes and coyotes are probably the most common predators, with bobcats and lynx also preying on them in more remote locations.
European hares have both external and internal parasites. One study found that 54% of animals in Slovakia were parasitised by nematodes and over 90% by coccidia. In Australia, European hares were reported as being infected by four species of nematode, six of coccidian, several liver flukes and two canine tapeworms. They were also found to host rabbit fleas (Spilopsyllus cuniculi), stickfast fleas (Echidnophaga myrmecobii), lice (Haemodipsus setoni and H. lyriocephalus), and mites (Leporacarus gibbus).
European brown hare syndrome (EBHS) is a disease caused by a calicivirus similar to that causing rabbit haemorrhagic disease (RHD) and can similarly be fatal, but cross infection between the two mammal species does not occur. Other threats to the hare are pasteurellosis, yersiniosis (pseudo-tuberculosis), coccidiosis and tularaemia, which are the principal sources of mortality.
In October 2018, it was reported that a mutated form of the rabbit haemorrhagic disease virus (RHDV2) may have jumped to hares in the UK. Normally rare in hares, a significant die-off from the virus has also occurred in Spain.


The white-tailed jackrabbit is native to western and central parts of North America. Its range includes British Columbia, Alberta, Saskatchewan, Manitoba and Ontario in Canada and Washington, Oregon, California, Nevada, Utah, Idaho, Montana, Wyoming, Colorado, New Mexico, North Dakota, South Dakota, Nebraska, Kansas, Minnesota, Wisconsin, Iowa, Missouri and Illinois in the United States. It is found in plains and prairie and in alpine meadows with scattered coniferous trees up to an elevation of about 3,000 m (10,000 ft) in Colorado. The white-tailed jackrabbit is slightly larger than the black-tailed jackrabbit (Lepus californicus) and where their ranges overlap, they are segregated by their habitat, as the former tends to live in higher altitudes and the latter in more arid lowland habitats.
Whitetails are often seen in urban parks and on suburban parks in Western Canada.  People often come across bunnies alone during the day in spring and mistakenly assume they are abandoned by their mothers.  The Edmonton Humane Society has issued public statements asking that bunnies not be brought into animal shelters.


At least the following states have restrictions on this plant: Colorado, Kansas, Nebraska, and New York.


L. dryas is found in a band around the world from 40° north to 60° north across central Europe and Asia from France to the Pacific and across North America. L. dryas is the only Lestes that occurs in Europe and in North America. Around the Mediterranean it is found at altitude. It is found in still, shallow water in well vegetated ditches, ponds, bogs and lakes. It can be found near the coast in slightly brackish water. It is widespread in Europe but is never as common as L. sponsa.
It was believed to be extinct in Britain before being rediscovered in 1983. Since then it has been found at several sites in south-east England. They breed mainly round the Thames Estuary and in a few inland lakes in Norfolk and Ireland.


The sweetflag spreadwing (Lestes forcipatus) is a species of damselfly in the family Lestidae, the spreadwings. It is native to North America, especially eastern parts of Canada and the United States.


Lestes vigilax, the swamp spreadwing, is a damselfly of the genus Lestes. It grows between 42 and 55 mm long. It ranges from eastern North America west to Minnesota, Oklahoma, and Texas, and to Georgia and South Carolina. It is most commonly seen between May and October.


As with many of the most well known Leucocoprinus species the taxonomic history of this species is complex with numerous early mycologists classifying it independently before the species were later merged. As a result the authorities recognised today aren't necessarily the first to document this species but rather the first to document the basionym which ultimately ended up classified as Leucocoprinus fragilissimus.
The first description of this species was made in 1805 by Johannes Baptista von Albertini and Lewis David de Schweinitz who classified it as Agaricus flammula. This basionym was reclassified as Lepiota flammula in 1874 by the French botanist Claude Casimir Gillet and then Pholiota flammula in 1912 by the Italian mycologist Vincenzo Migliozzi.
In 1853 Hiatula fragilissima was described by the British botanist Miles Joseph Berkeley and the American botanist Moses Ashley Curtis based on an earlier unofficial classification by the American botanist Henry William Ravenel. In 1907 the American mycologist Andrew Price Morgan reclassified the species as Lepiota fragilissima however it had already been was reclassified as Leucocoprinus fragilissimus in 1900 by Patouillard.
In addition to these basionyms, in 1871 Agaricus licmophorus was described by Berkeley and the British mycologist Christopher Edmund Broome. This went on to be reclassified as Lepiota licmophora by the Italian mycologist Pier Andrea Saccardo in 1887 and then Mastocephalus licmophorus by the German botanist Otto Kunze in his extensive proposed list of reclassifications of 1891. However no species remain within this genus.
In 1888 the French mycologist Narcisse Théophile Patouillard described the novel species Leucocoprinus flavipes which Saccardo reclassified as Hiatula flavipes in 1891 citing Hiatula fragilissimoe as a similar species. In 1910 the British mycologist Thomas Petch reclassified this species as Hiatula licmophora and stated that it was probable that it was identical to Leucocoprinus flavipes and Hiatula fragilissima. Nonetheless H. licmophora was finally reclassified as Leucocoprinus licmophorus by Patouillard in 1913. In 1972 this was reclassified as Leucocoprinus fragilissimus by the British mycologist David Pegler.
This confusing history full of competing names is typical of many of the Leucocoprinus species documented from greenhouses and plant pots since the mushrooms started appearing all over Europe after exotic plants were brought back from the tropics. With only written descriptions and illustrations to compare as well as the slow rate of information dissemination that came from printed journals it is to be expected that these species were originally described numerous times.


Leucorrhinia frigida, the frosted whiteface, is a species of dragonfly in the family Libellulidae. It is found in northeastern United States and southern Manitoba, Ontario, Quebec, and New Brunswick.


The plant is native to western North America from low to moderate elevations on grassland, open bushland, forest in dry rocky or gravelly soils. Its range extends from southern British Columbia, through Washington and Oregon west of the Cascade Range to southern California, and east to western Montana, Wyoming, northern Colorado and northern Arizona.


Liatris spicata, the dense blazing star or prairie feather, is a herbaceous perennial flowering plant in the family Asteraceae. It is native to eastern North America where it grows in moist prairies and sedge meadows.
The plants have tall spikes of purple flowers resembling bottle brushes or feathers that grow 1–5 ft (0.30–1.52 m) tall. The species grows in hardiness zones 3 - 8, stretching from the Midwest to the East Coast, eastern and western Canada.
Common varieties include 'Alba' and 'Floristan White' which are white-flowering cultivars on 18 in (46 cm) tall spikes, 'Callilepsis' with long stems good for cut flowers, 'Floristan Violett' with a strong stem and thick, violet flower spikes preferred by florists, and 'Kobold' which stays small in size with deep purple flowers.
Liatris spicata var. resinosa is found in the southern part of the species's natural range. The variable plants have only 5 or 6 flowers per head and the heads are more widely spaced on the stems; these differences are more pronounced when the plants are found in drier and coastal habitats.


Libellula semifasciata, the painted skimmer, is an uncommon eastern North American skimmer dragonfly, found from New Brunswick, Canada as far south as Texas and Florida.
It is a medium-sized species, at 43 mm (1.7 in) long. Each wing is amber coloured at the base and wing tip and has several brown spots. The abdomen has a lateral strip that is white anteriorly and yellow posteriorly.


The brown honeyeater was originally described by Nicholas Aylward Vigors and Thomas Horsfield in 1827 as Meliphaga indistincta. The species name indistincta is from the Latin word meaning 'indistinct, obscure'. Vigors and Horsfield were working from the bird collection of the Linnean Society in London, and they said of the brown honeyeater specimen, "It is however in very bad condition, and scarcely admits of a description." Later included in the "catch-all" genus Gliciphila, the brown honeyeater is now classified as a member of the genus Lichmera, from the Greek word meaning 'to lick' or 'to dart the tongue', following Schodde (1975), Sibley and Monroe (1990) and Christidis and Boles (1994). As well as the nominate race Lichmera indistincta indistincta, a number of other subspecies are recognised: ocularis (derived from the Medieval Latin word oculus meaning 'eye'), melvillensis (named for Melville Island where it is found), limbatus (from the Latin for 'fringed') and nupta (from the Latin nubere meaning 'to marry'). The Indonesian honeyeater (subspecies limbatus) was previously considered a distinct species due to its disjunct range, but is now treated as a subspecies of L. indistincta by major taxonomic authorities. A 2017 genetic study using both mitochondrial and nuclear DNA confirms the close relationship between the two, their lineages having diverged recently (in the order of tens of thousands of years).
Molecular analysis has shown honeyeaters to be related to the Pardalotidae (pardalotes), Acanthizidae (Australian warblers, scrubwrens, thornbills, etc.), and the Maluridae (Australian fairy-wrens) in the large superfamily Meliphagoidea.


The brown honeyeater is found in a wide range of wooded habitats, and is widespread across Australia. The nominate race ranges across a broad band from Newcastle on the New South Wales coast north and west to Queensland and the Top End to southwestern Western Australia. It is rarely seen in Sydney, where populations have declined since the late 1950s, though it is being recorded in suitable habitats, such as Homebush Bay and Kurnell in small numbers, and is a vagrant to the Illawarra region. It is rare in South Australia, and not present in Victoria and Tasmania. Population densities range from 2.3 birds per 1 hectare (2.5 acres) in the Kakadu National Park, to 0.26 birds per hectare in Wellard in Western Australia.
L. i. ocularis is found in New Guinea, the Torres Strait Islands, and Cape York intergrading with the nominate race along the Gulf of Carpentaria river system. L. i. melvillensis inhabits the Tiwi Islands, while L. i. limbata is found in Bali and the Lesser Sundas, and L. i. nupta on the Aru Islands.
The brown honeyeater is seasonally nomadic across its local area in response to flowering food plants. For example, there are marked increases in numbers in Toowoomba in southeast Queensland during winter, and in the Northern Territory the range contracts during the dry season. It is commonly found among mangroves in coastal areas including black mangroves (Rhizophora mucronata). It is often in woodlands that merge into the mangroves, such as those dominated by Banksia, Melaleuca or Callistemon, and widespread in sclerophyll forests and eucalypt woodlands. In the arid and semi-arid inland of Australia, it is most often recorded in Acacia, Grevillea and Hakea shrubland along watercourses, and at bores, springs, and drainage lines. It visits flowering shrubs in parks and gardens, and occurs in remnant patches of trees on travelling stock routes.


Within the British Isles, Ligusticum scoticum is only found on coasts where the mean July temperature is below 15 °C (59 °F), and this bound is likely also to apply in other parts of the species' range. Towards the southern end of its range, the plant performs poorly on south-facing sites. It grows in fissures in rocks, where it may be the only vascular plant, and also in cliff-top grassland communities dominated by Festuca rubra and Plantago maritima.
Ligusticum scoticum cannot tolerate grazing, and is harmed by the actions of nesting seabirds; it is therefore rarely found on bird cliffs, or where grazing sheep and rabbits are found. It is, however, tolerant of salt spray, and its growth has been shown to improve when given dilute sea water. The leaves of L. scoticum are frost-tolerant, and die back each winter, but regrow very rapidly the following spring. In the British Isles, flowering occurs from June to August, and the seeds are ripe in October or November; the timing is expected to be later at higher latitudes. The flowers of L. scoticum are visited by generalist pollinators, mostly flies.


Ligustrum means 'binder'. It was named by Pliny and Virgil.
Quihoui was named for M. Quihou, once superintendent of the Jardin d'Acclimatation in Paris.


The lily leaf beetle is indigenous to parts of Europe and Asia. It is thought to have been introduced to North America through the importation of plant bulbs in 1943. First spotted in Montreal, it spread throughout Canada and appeared in Massachusetts in 1992, and by 2012 was in all six New England States, as well as New York and Washington states. In Canada it is found from the Maritime Provinces west to Manitoba. As of 2001, it spread as far west as Alberta, and as of 2017 full infestations reported as far north as the Edmonton, AB area. It has also become established as an invasive species in the United Kingdom since being first recorded in 1839, although the first colony did not become established until 1939 and it did not spread far until the 1980s, then more rapidly from the 1980s. Since then it has spread from Surrey in southern England as far north as Inverness, Scotland. It is also found in Ireland. It is also found in the Middle East and North Africa.


Fritillaria and Lilium specimens in Canadian gardens, particularly around Halifax, Nova Scotia are significantly affected by the lily leaf beetle. A garden in Waverley, Nova Scotia has reported decline of lily species and cultivars from 50 in 1996 to only one in 2006.


It is listed Rare in Indiana, as Exploitably Vulnerable in New York (state), and as Threatened in Rhode Island and Tennessee.


Limnanthes douglasii is a species of annual flowering plant in the family Limnanthaceae (meadowfoam) commonly known as Douglas' meadowfoam or poached egg plant. It is native to California and Oregon, where it grows in wet, grassy habitat, such as vernal pools and spring meadows. It can grow in poorly drained clay soils. The plant was collected by the Scottish explorer and botanist David Douglas, who worked on the west coast of America in the 1820s.
The plant usually bears white flowers with yellow centers, hence the name "poached egg plant", but flower color can vary across subspecies. It is a popular ornamental plant. It attracts hoverflies and is pollinated by bees. It is self-seeding, even in a lawn.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.
There are six subspecies:
L. douglasii subsp. douglasii R. Br., is native to the coastal mountains and valleys of southwestern Oregon south to the San Francisco Bay Area
L. douglasii subsp. nivea (C.T. Mason) C.T. Mason, with mostly white flowers, grows in the coastal mountains of northern California
L. douglasii subsp. ornduffii (E. G. Buxton), with 4 petals instead of 5, is endemic to California's San Mateo County
L. douglasii subsp. rosea (Benth.) C.T. Mason, found in California's Central Valley and adjacent hills, often has pink veining on its petals
L. douglasii subsp. sulphurea (C.T. Mason) C.T. Mason, is a rare yellow-petaled subspecies endemic to the Bay Area
L. douglasii subsp. striata (Jeps.) Morin, has recently been subsumed into this species; it occurs in the Klamath range and the north and central Sierra Nevada


The short-billed dowitcher (Limnodromus griseus), like its congener the long-billed dowitcher, is a medium-sized, stocky, long-billed shorebird in the family Scolopacidae. The genus name Limnodromus is  Ancient Greek  from limne, "marsh" and dromos, "racer". The specific griseus is Medieval Latin for "grey". The English name is from Iroquois and was first recorded in 1841.
It is an inhabitant of North America, Central America, the Caribbean, and northern South America. It is strongly migratory; it completely vacates in breeding areas during the snow-bound months. This species favors a variety of habitats including tundra in the north to ponds and mudflats in the south. It feeds on invertebrates often by rapidly probing its bill into mud in a sewing machine fashion. It and the very similar long-billed dowitcher were considered one species until 1950. Field identification of the two American Limnodromus remains difficult today. Distinguishing wintering or juvenile short-billed dowitchers from the long-billed species is very difficult and, even given examination their subtlety different body shapes, cannot always be isolated to a particular species. They differ most substantially in vocalizations. The names of American dowitchers are misleading, as there is much overlap in their bill lengths. Only a small percentage can be identified by this character alone.


During the non-breeding season, its range has been difficult to determine due to its similarity to Short-billed dowitchers in winter plumage, especially in areas where both species overlap in which case most birds are identified as "Dowitchers". Along the Pacific coast however, it winters in various locations from south-western British Columbia to Baja California, also moving inland to Arizona, New Mexico, Texas, and south to Mexico. Along the Atlantic coast, it winters from North Carolina to Florida, also moving west along the Gulf Coast to Mississippi, Louisiana, and Texas. In the winter, this bird can be found in a much larger variety of habitats ranging from mudflats, flooded wetlands, wet meadows and fields to various lakes and marshes preferring water less than three inches deep. In general, Long-billed dowitchers seem to prefer fresh over salt water and muddy over sandy habitats in comparison to Short-billed dowitchers.


The bar-tailed godwit is a non-breeding migrant in Australia and New Zealand. Birds first depart for their northern hemisphere breeding sites at age 2–4. Breeding take place each year in Scandinavia, northern Asia, and Alaska. The nest is a shallow cup in moss sometimes lined with vegetation. Clutch size is from 2 to 5, averaging four. Both sexes share incubation of the eggs for 20 to 21 days, the female during the day and the male at night.


The black-tailed godwit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax limosa. It is now placed with three other godwits in the genus Limosa that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The name Limosa is from Latin and means "muddy", from limus, "mud". The English name "godwit" was first recorded in about 1416–17 and is believed to imitate the bird's call.
Four subspecies are recognised:
L. l. islandica – Brehm, 1831: the Icelandic black-tailed godwit, which breeds mostly in Iceland, but also on the Faeroe Islands, the Shetland and the Lofoten Islands. It has a shorter bill, shorter legs and more rufous coloration extending onto the belly, compared to limosa.
L. l. limosa – (Linnaeus,1758): the European black-tailed godwit, which breeds from western and central Europe to central Asia and Asiatic Russia, as far east as the Yenisei River. Its head, neck and chest are pale orange.
L. l. melanuroides – Gould, 1846: the Asian black-tailed godwit, which breeds in Mongolia, northern China, Siberia and Far Eastern Russia. Its plumage is similar to islandica, but the bird is distinctly smaller.
L. l. bohaii – Zhu, Piersma, Verkuil & Conklin, 2020: assumed to breed in Russian Far East; non-breeding in northeast China, Hong Kong, Vietnam, Peninsular Malaysia


Linanthus dianthiflorus is a species of flowering plant in the phlox family known by the common names fringed linanthus and ground pink.
The annual wildflower is endemic to southern California, in the Peninsular Ranges, Transverse Ranges, and on the Channel Islands. It can be found in many types of local open habitat, such as chaparral.


The common linnet breeds in Europe, the western Palearctic and North Africa. It is partially resident, but many eastern and northern birds migrate farther south in the breeding range or move to the coasts. They are sometimes found several hundred miles off-shore. It has been introduced to the Dominican Republic.


The bird was a popular pet in the late Victorian and Edwardian eras. Alfred, Lord Tennyson mentions "the linnet born within the cage" in Canto 27 of his 1849 poem "In Memoriam A.H.H.", the same section that contains the famous lines "'Tis better to have loved and lost / Than never to have loved at all." A linnet features in the classic British music hall song "Don't Dilly Dally on the Way" (1919) which is subtitled "The Cock Linnet Song". It is a character in Oscar Wilde's children's story "The Devoted Friend" (1888) and Wilde also mentions how the call of the linnet awakens "The Selfish Giant" to the one tree where it is springtime in his garden. William Butler Yeats evokes the image of the common linnet in "The Lake Isle of Innisfree" (1890) : "And evening full of the linnet's wings." and also mentions the bird in his poem "A Prayer for My Daughter" (1919): "May she become a flourishing hidden tree That all her thoughts may like the linnet be, And have no business but dispensing round Their magnanimities of sound." In the 1840 novel The Old Curiosity Shop by Charles Dickens, the heroine Nell keeps "only a poor linnet" in a cage, which she leaves for Kit as a sign of her gratefulness to him.
The English Baroque composer John Blow composed an ode on the occasion of the death of his colleague Henry Purcell, "An Ode on the Death of Mr. Purcell" set to the poem "Mark how the lark and linnet sing" by the poet John Dryden.
"The Linnets" has become the nickname of King's Lynn Football Club, Burscough Football Club and Runcorn Linnets Football Club (formerly known as 'Runcorn F.C.' and Runcorn F.C. Halton). Barry Town F.C., the South Wales-based football team, also used to be nicknamed 'The Linnets'.
Robert Burns's 1788 poem "A Mother's Lament for the Death of Her Son" also tells of a linnet bird bewailing her ravished young.
William Blake invokes "the linnet's song" in one of the poems entitled "Song" in his Poetical Sketches.
Walter de la Mare's poem "The Linnet", published in 1918 in the collection Motley and Other Poems, has been set to music by a number of composers including Cecil Armstrong Gibbs, Kenneth Leighton and Jack Gibbons.
The Eurovision Song Contest 2014 entry for the Netherlands "The Common Linnets" is a direct reference to the bird.
William Wordsworth argued that the song of the common linnet provides more wisdom than books in the third verse of "The Tables Turned":
Books! 'tis a dull and endless strife:

Come, hear the woodland linnet,

How sweet his music! on my life,

There's more of wisdom in it.
But the fellow English poet Robert Bridges used the common linnet instead to express the limitations of poetry—concentrating on the difficulty in poetry of conveying the beauty of a bird's song. He wrote in the first verse:
I heard a linnet courting

His lady in the spring:

His mates were idly sporting,

Nor stayed to hear him sing

His song of love.—

I fear my speech distorting

His tender love.
The musical Sweeney Todd features the song "Green Finch and Linnet Bird", in which a young lady confined to her room wonders why caged birds sing:
Green finch and linnet bird,

Nightingale, blackbird,

How is it you sing?

How can you jubilate,

Sitting in cages,

Never taking wing?
In Emily Dickinson's poem "Morns like these—we parted—" the last line is: "And this linnet flew!"


Seeds of the common toadflax, were identified from the Hoxnian interglacial strata at Clacton. Records have also come from the Weichselian glaciation strata in Essex, Huntingdonshire, Surrey and North Wales. This evidence makes the native status of the plant in Britain quite evident despite the very strong association that it has today with waste places and man-made habitats.


Lindernia dubia is a species of flowering plant known by the common names yellowseed false pimpernel and moist bank pimpernel. It is a member of the "new" plant family Linderniaceae, and it is sometimes treated as a member of the families Scrophulariaceae and Plantaginaceae. It is native to much of the Americas from Canada to Chile, and it can be found on other continents as an introduced species. It grows in wet habitat, such as riverbanks, pond margins, and meadows. It is an annual herb growing a mostly erect, branching stem to exceed 30 centimeters in height. The oppositely arranged leaves vary in size and shape, from lance-shaped to oval, toothed or not, and under one to over three centimeters long. Flowers emerge from upper leaf axils. Each has a calyx of five narrow, linear sepals. The tubular corolla is up to a centimeter long, white in color with a blue or purple tint, and lipped at the mouth, the lower lip with three rounded lobes. The fruit is a capsule containing yellow seeds.


Liometopum occidentale, also called the velvety tree ant, is a species of ant in the subfamily Dolichoderinae. Liometopum occidentale is often mistaken for carpenter ants (Camponotus spp.) by homeowners and pest management professionals. This mistaken identity is due to morphological and behavioral characteristics they share with carpenter ants; namely polymorphic workers, a smooth convex thoracic profile, and the tendency to excavate wood. Consequently, their importance as structural pests may be greatly under reported, especially in California, Oregon, and Washington, United States.


An ancestor of Liquidambar styraciflua is known from Tertiary-aged fossils in Alaska, Greenland, and the mid-continental plateau of North America, much further north than Liquidambar now grows.  A similar plant is also found in Miocene deposits of the Tertiary of Europe.


The smooth newt, European newt, northern smooth newt or common newt (Lissotriton vulgaris) is a species of newt. It is widespread in Europe and parts of Asia, and has been introduced into Australia. Individuals are brown with a spotted underside that ranges in color from orange to white. They reach an average length of 8–11 cm (3.1–4.3 in); males are larger than females. The newts' skins are dry and velvety when they are living on land, but become smooth when they migrate into the water to breed. Males develop a more vivid colour pattern and a conspicuous skin seam (crest) on their back when breeding.
The smooth newt was originally described by Carl Linnaeus as a lizard, and was then given different genus names before the adoption of its current classification as a member of Lissotriton. There are currently three accepted subspecies of smooth newt. Formerly, there were also four subspecies—all with more restricted ranges—that are now classified as separate species, because they have been found to be distinct genetically as well as in appearance: the Caucasian smooth newt, the Greek smooth newt, Kosswig's smooth newt and Schmidtler's smooth newt. Together with these four species and the Carpathian newt, the smooth newt forms what is known as a species complex: some of the species hybridise with each other.
For most of the year, smooth newts live on land, are mostly nocturnal, and hide during the day. They can adapt to a wide range of natural or semi-natural habitats, from forests at field edges to parks and gardens. They feed mainly on invertebrates such as insects and earthworms and are themselves eaten mainly by fish, birds and snakes. Between spring and summer, they breed in ponds or similar bodies of water. Males court females with a ritualised underwater display. Females lay their eggs on water plants, and larvae hatch after 10 to 20 days. The larvae develop for around three months before metamorphosing into terrestrial juveniles, at which point they become known as efts. They reach maturity after two to three years, and the adults live for up to 14 years.
The smooth newt is abundant over much of its range and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN). It has been negatively affected by habitat destruction and fragmentation and by the introduction of new species of fish. Like other European amphibians, the smooth newt has now been listed as a protected species by the Berne Convention.


The smooth newt has been described as "the most ubiquitous and widely distributed newt of the Old World". The nominate subspecies, L. v. vulgaris, is most widespread and ranges natively from Ireland (where the smooth newt is the only newt species) and Great Britain in the west to Siberia and northern Kazakhstan in the east. In the north it reaches central Fennoscandia, and its southern limit is central France, northern Italy, the central Balkans and the dry Eurasian steppe of Ukraine and Russia. The subspecies L. v. ampelensis only occurs in the Carpathians of Ukraine and the Danube delta of northern Romania, and L. v. meridionalis in the northern half of Italy, southern Switzerland, Slovenia and Croatia.
In the Carpathians, the smooth newt generally prefers lower elevations than the Carpathian newt. In the Balkans, the precise contact zones with the Greek smooth newt and Schmidtler's smooth newt are not yet clear. In central Italy, where the range of the smooth newt subspecies L. v. meridionalis overlaps with that of the Italian newt (L. italicus), it was found that the latter prefers a warmer and drier climate.


The smooth newt is common over much of its range. The IUCN, in 2008, assessed its threat status as Least Concern and found no general decline in populations. This assessment included subspecies now recognised as separate species (see section Taxonomy above) and needs updating. Despite the overall low concern, the smooth newt is listed in some national red lists, e.g. in Switzerland, the Czech Republic, and the Netherlands. Like all amphibians, it is also listed as protected species in the Berne Convention (Appendix III). Disturbance, capture, killing and trade are prohibited in Ireland under the Wildlife Act 1976, and trade in the UK under the Wildlife and Countryside Act 1981.
Threats to smooth newts are similar to those affecting other amphibians. They include especially the loss of breeding ponds through destruction or introduction of fish, and the fragmentation of population through roads. Secondary habitats can help sustain the species, e.g. former gravel pits or quarries left open. The value of artificial water bodies as habitat can be improved when nearby hiding structures like stones or wood are added on land. Garden ponds are readily colonised if they are sun-exposed, have abundant water plants, no fish, and nearby hiding structures. Artificial hibernation sites ("newt hotels") were readily used in a study in Norway, especially by juveniles.
To mark and track individuals and monitor populations, researchers have often amputated phalanges of fingers and toes but these re-grow quickly; a safer and less harmful alternative is recording the individual belly patterns through photography. Researchers have also developed genetic methods based on microsatellite distribution to assess patterns of genetic diversity.


The Plains leopard frog, as its name implies, is found throughout the Great Plains of the United States, from Indiana west across central and southern plains to South Dakota, south to Colorado, New Mexico, and Texas, with a disjunct population in Arizona.


The American bullfrog provides a food source, especially in the Southern and some areas of the Midwestern United States. The traditional way of hunting them is to paddle or pole silently by canoe or flatboat in ponds or swamps at night; when the frog's call is heard, a light is shone at the frog which temporarily inhibits its movement. The frog will not jump into deeper water as long as it is approached slowly and steadily. When close enough, the frog is gigged with a multiple-tined spear and brought into the boat. Bullfrogs can also be stalked on land, by again taking great care not to startle them. In some states, breaking the skin while catching them is illegal, and either grasping gigs or hand captures are used. The only parts normally eaten are the rear legs, which resemble small chicken drumsticks, have a similar flavor and texture and can be cooked in similar ways.
Commercial bullfrog culture in near-natural enclosed ponds has been attempted, but is fraught with difficulties. Although pelleted feed is available, the frogs will not willingly consume artificial diets, and providing sufficient live prey is challenging. Disease also tends to be a problem even when great care is taken to provide sanitary conditions. Other challenges to be overcome may be predation, cannibalism, and low water quality. The frogs are large, have powerful leaps, and inevitably escape after which they may wreak havoc among the native frog population. Countries that export bullfrog legs include the Netherlands, Belgium, Mexico, Bangladesh, Japan, China, Taiwan, and Indonesia. Most of these frogs are caught from the wild, but some are captive-reared. The United States is a net importer of frog legs.
The American bullfrog is used as a specimen for dissection in many schools across the world. It is the state amphibian of Missouri, Ohio, and Oklahoma.


The pickerel frog ranges in the west from much of Wisconsin, southeast Minnesota, eastern Iowa, through Missouri and down to eastern Texas. To the east they extend through northern Louisiana, most of Mississippi, northern Alabama, Georgia, and South Carolina to the coast. Their northern range extends into Canada in the southern reaches of Ontario, Quebec, New Brunswick, and Nova Scotia. The range is spotty through the midwestern states and a field guide should be obtained for the specifics on ranges in a particular area.


The northern leopard frog (Lithobates pipiens or Rana pipiens) is a species of leopard frog from the true frog family, native to parts of Canada and the United States. It is the state amphibian of Minnesota and Vermont.


Northern leopard frogs have a wide range of habitats. They are found in permanent ponds, swamps, marshes, and slow-moving streams throughout forest, open, and urban areas. They normally inhabit water bodies with abundant aquatic vegetation. In the summer, they often abandon ponds and move to grassy areas and lawns. They are well adapted to cold and can be found above 3,000 m (9,800 ft) above mean sea level. Males make a short, snore-like call from water during spring and summer. The northern leopard frog breeds in the spring (March–June). Up to 6500 eggs are laid in water, and tadpoles complete development within the breeding pond. Tadpoles are light brown with black spots, and development takes 70–110 days, depending on conditions. Metamorph frogs are 2–3 cm (0.79–1.18 in) long and resemble the adult.
This species was once quite common through parts of western Canada and the United States until declines started occurring during the 1970s. Although the definitive cause of this decline is unknown, habitat loss and fragmentation, environmental contaminants, introduced fish, drought, and disease have been proposed as mechanisms of decline and are likely preventing species' recovery in many areas. Many populations of northern leopard frogs have not yet recovered from these declines.
Northern leopard frogs are preyed upon by many different animals, such as snakes, raccoons, other frogs, and even humans. They do not produce distasteful skin secretions and rely on speed to evade predation.
They eat a wide variety of animals, including crickets, flies, worms, and smaller frogs. Using their large mouths, they can even swallow birds and garter snakes. In one case, a bat was recorded as prey of this frog. This species is similar to the pickerel frog (Lithobates palustris) and the southern leopard frog (Lithobates sphenocephalus).


Northern leopard frogs occur from Great Slave Lake and Hudson Bay, Canada, south to Kentucky and New Mexico, USA. It is also found in Panama, where it is endemic to the central cordillera and western Pacific lowlands, although this is most likely an undescribed species. They occupy grasslands, lakeshores, and marshes.


Mink frogs are found in the United States in the states of Minnesota, New Hampshire, Wisconsin, Michigan, Maine, Vermont, and New York. They are also found in Canada in the provinces of Nova Scotia, New Brunswick, Newfoundland and Labrador, Quebec, Ontario, and Manitoba. This largely aquatic frog's southern range limit is at the highest latitude of any North American frog and there is evidence that more southern populations of this frog became extinct within the past century.


Lithospermum incisum is a species of flowering plant in the borage family known by several common names, including fringed puccoon, narrowleaf stoneseed, fringed gromwell, narrowleaf puccoon, and plains stoneseed. It is native to much of central Canada and the United States, where it is known from many types of habitat, but particularly piñon-juniper woodland. It is a hairy perennial herb growing from a taproot and woody caudex. It produces a cluster of stems up to about 30 centimeters long. The stems are lined with narrow, pointed leaves up to 6 centimeters long. The slender, trumpet-shaped flowers are pale to bright yellow or gold, and may approach 4 centimeters long. The corolla face is 1 to 2 centimeters wide, its lobes sometimes ruffled. The smaller cleistogamous (closed) flowers are the main producers of seed.


L. migratoria is found over a vast geographic area, and its range covers many different ecological zones.  Because of this, numerous subspecies have been described; however, not all experts agree on the validity of some of these subspecies.
L. m. burmana Ramme, 1951
L. m. capito Saussure, 1884 (Malagasy migratory locust: Madagascar)
L. m. cinerascens Fabricius, 1781 (Italy, Spain)
L. m. manilensis (Meyen, 1835) 1 (eastern Asia)
L. m. migratoria (Linnaeus, 1758) (Eurasian migratory locust: West and Central Asia, eastern Europe)
L. m. migratorioides (Fairmaire & L.J. Reiche, 1849) (African migratory locust: Africa and Atlantic islands)
L. m. tibetensis Chen, Yonglin, 1963
L. m. danica (Linnaeus, 1767) = L. m. migratoria (Linnaeus, 1758)
L. m. gallica Remaudičre, 1947 =  L. m. migratoria (Linnaeus, 1758)
L. m. solitaria Carthy, 1955 = L. m. migratoria (Linnaeus, 1758)


Lolium perenne, common name perennial ryegrass, English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.


Perennial ryegrass is native to southern Europe, the Middle East, North Africa and eastwards to central Asia. As a useful species of grass for fodder and grazing livestock, it has been taken by farmers settling in new areas including North America, South Africa and Australia. It can be used to prevent erosion and to stabilise soils, as well as creating a hardwearing turf for lawns and golf courses. With its great ability to set seed, its ease of germination and vigour, it has spread from the fields where it has been planted to roadsides, trackways, footpaths, wasteland, river banks and sand dunes. In countries where it has been introduced, it may be regarded as an invasive species that competes with native plants.


Perennial ryegrass is an important pasture and forage plant, and is used in many pasture seed mixes. In fertile soil, it produces a high grass yield, and in Britain and Ireland, it is frequently sown for short-term ley grassland, often with red or white clover (Trifolium).
In Britain, it is also used as an indicator of nonspecies-rich grassland, as it outcompetes the rarer plants and grasses, especially in fertile soils. Agri-environment schemes such as the Countryside Stewardship Scheme, Environmentally Sensitive Areas Scheme, and Environmental Stewardship give funding to species-rich grasslands that do not have an abundance of ryegrass.
Selected seed mixes are used extensively for sports pitches, especially winter sports in temperate climates, because of its wear resistance and ability to regenerate.
It is commonly used in the southwest United States to overseed winter lawns. Bermudagrass is a typical summertime grass in states such as Arizona, since it is able to withstand the high temperatures. However, bermudagrass goes dormant during the cooler winter months.  Rather than have brown lawns, many homeowners, public areas, and golf courses overseed these lawns with perennial ryegrass in early to mid-September.
It is also the grass used on the courts at the All England Lawn Tennis Club in Wimbledon. Since 2001, the courts have been sown with 100% perennial ryegrass to "improve durability and strengthen the sward to withstand better the increasing wear of the modern game".


The Zabulon skipper (Lon zabulon) (sometimes called the southern dimorphic skipper) is a North American butterfly first described by the French naturalists Jean Baptiste Boisduval and John Eatton Le Conte from the state of Georgia, United States.


Recorded food plants of the caterpillars are grasses such as Agrostis, Dactylis, Elytrigia, Eragrostis, Leymus, Poa, Puccinellia and Tridens.


In 1760 the French zoologist Mathurin Jacques Brisson included a description of the white-rumped munia in his Ornithologie based on a specimen that he believed had been collected from the Isle de Bourbon (Réunion). The specimen is now assumed to have come from Sri Lanka. He used the French name Le gros-bec de l'Isle de Bourbon and the Latin Coccothraustes Borbonica. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the white-rumped munia. Linnaeus included a brief description, coined the binomial name Loxia striata and cited Brisson's work. The specific name striata is Latin for "striated ". This species is now placed in the genus Lonchura that was introduced by the English naturalist William Henry Sykes in 1832.
There are six subspecies:
L. s. acuticauda (Hodgson, 1836) –  northern Indian mainland below c. 1,500 metres ASL, north through the Himalayas foothills of Bhutan and Nepal to the Dehradun region of Uttarakhand, India across to Bangladesh to northern Indochina
Medium brown above, except on the face and remiges, buffy below
L. s. striata (Linnaeus, 1766) – southern Indian mainland, Sri Lanka
Dark chocolate-brown above, white below
L. s. fumigata (Walden, 1873) – Andaman Islands
L. s. semistriata (Hume, 1874) – Car Nicobar and Central (Nancowry) group, Nicobar Islands
L. s. subsquamicollis (Baker, ECS, 1925) – Malay Peninsula to southern Indochina
L. s. swinhoei (Cabanis, 1882) – east central and east China, Taiwan
A domesticated hybrid called the society finch, sometimes called Lonchura domestica is said by some sources to have L. s. striata in its ancestry, although other theories suggest contributions from the white-throated munia. The hybrid with numerous variants in plumage are thought to have been established by aviculturists in Japan.


The long-crested eagle occurs in sub-Saharan Africa from Senegal and Gambia eastwards to Ethiopia and south to the Eastern Cape, in South Africa, northern Namibia and northern Botswana. It is generally regarded as sedentary, but in arid areas may be nomadic depending on the rains.


Lophocampa argentata, the silver-spotted tiger moth, is a species of moth in the family Erebidae. It was described by Packard in 1864. It is found from British Columbia to southern California, and east to Arizona, Nevada, New Mexico, Colorado, Utah, Wyoming and possibly to northern Mexico.
Larvae of this moth utilize numerous host plants in western North America, notably including the Douglas-fir.


The European crested tit, or simply crested tit (Lophophanes cristatus) (formerly Parus cristatus), is a passerine bird in the tit family Paridae. It is a widespread and common resident breeder in coniferous forests throughout central and northern Europe and in deciduous woodland in France and the Iberian peninsula. In Great Britain, it is chiefly restricted to the ancient pinewoods of Inverness and Strathspey in Scotland, and seldom strays far from its haunts. A few vagrant crested tits have been seen in England. It is resident, and most individuals do not migrate.


The peyote (/peɪˈoʊti/; Lophophora williamsii /ləˈfɒfərə wɪliˈæmziaɪ/) is a small, spineless cactus which contains psychoactive alkaloids, particularly mescaline. Peyote is a Spanish word derived from the Nahuatl peyōtl ([ˈpejoːt͡ɬ]), meaning "caterpillar cocoon", from a root peyōni, "to glisten". Peyote is native to Mexico and southwestern Texas. It is found primarily in the Sierra Madre Occidental, the Chihuahuan Desert and in the states of Nayarit, Coahuila, Nuevo León, Tamaulipas, and San Luis Potosí among scrub. It flowers from March to May, and sometimes as late as September. The flowers are pink, with thigmotactic anthers (like Opuntia).
Known for its psychoactive properties when ingested, peyote has at least 5,500 years of entheogenic and medicinal use by indigenous North Americans.


In 2005, researchers used radiocarbon dating and alkaloid analysis to study two specimens of peyote buttons found in archaeological digs from a site called Shumla Cave No. 5 on the Rio Grande in Texas. The results dated the specimens to between 3780 and 3660 BCE. Alkaloid extraction yielded approximately 2% of the alkaloids including mescaline in both samples. This indicates that native North Americans were likely to have used peyote since at least five-and-a-half thousand years ago.
Specimens from a burial cave in west central Coahuila, Mexico have been similarly analyzed and dated to 810 to 1070 CE.
From earliest recorded time, peyote has been used by indigenous peoples, such as the Huichol of northern Mexico and by various Native American tribes, native to or relocated to the Southern Plains states of present-day Oklahoma and Texas. Its usage was also recorded among various Southwestern Athabaskan-language tribal groups. The Tonkawa, the Mescalero, and Lipan Apache were the source or first practitioners of peyote religion in the regions north of present-day Mexico. They were also the principal group to introduce peyote to newly arrived migrants, such as the Comanche and Kiowa from the Northern Plains. The religious, ceremonial, and healing uses of peyote may date back over 2,000 years.
Under the auspices of what came to be known as the Native American Church, in the 19th century, American Indians in more widespread regions to the north began to use peyote in religious practices, as part of a revival of native spirituality. Its members refer to peyote as "the sacred medicine", and use it to combat spiritual, physical, and other social ills. Concerned about the drug's psychoactive effects, between the 1880s and 1930s, U.S. authorities attempted to ban Native American religious rituals involving peyote, including the Ghost Dance. Today the Native American Church is one among several religious organizations to use peyote as part of its religious practice. Some users claim the drug connects them to God.
Traditional Navajo belief or ceremonial practice did not mention the use of peyote before its introduction by the neighboring Utes. The Navajo Nation now has the most members of the Native American Church.
John Raleigh Briggs (1851–1907) was the first to draw scientific attention of the Western scientific world to peyote. Louis Lewin described Anhalonium lewinii in 1888. Arthur Heffter conducted self experiments on its effects in 1897. Similarly, Norwegian ethnographer Carl Sofus Lumholtz studied and wrote about the use of peyote among the Indians of Mexico. Lumholtz also reported that, lacking other intoxicants, Texas Rangers captured by Union forces during the American Civil War soaked peyote buttons in water and became "intoxicated with the liquid".


The Wixarika religion consists of four principal deities: Corn, Kayumarie (Blue Deer), Hikuri (Peyote), and the Eagle, all descended from their Sun God. Schaefer has interpreted this to mean that peyote is the soul of their religious culture and a visionary sacrament that opens a pathway to the other deities.
