Unmanned aerial vehicle. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention.UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous.

Unmanned aerial vehicle. for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include forest fire monitoring, aerial photography, product deliveries, agriculture, policing and surveillance, infrastructure inspections, entertainment, science, smuggling, and drone racing.## Terminology.Many terms are used for aircraft which fly without any persons on board:The term drone has been used from the early days of aviation, being applied to remotely-flown target aircraft used for practice firing of a battleship's guns, such as the 1920s Fairey Queen and 1930s de Havilland Queen Bee. Later.

Unmanned aerial vehicle. examples included the Airspeed Queen Wasp and Miles Queen Martinet, before ultimate replacement by the GAF Jindivik. The term remains in common use. In addition to the software, autonomous drones also employ a host of advanced technologies that allow them to carry out their missions without human intervention, such as cloud computing, computer vision, artificial intelligence, machine learning, deep learning, and thermal sensors. For recreational uses, an aerial photography drone (as opposed to a UAV) is an aircraft that has first-person video, autonomous capabilities, or both.An unmanned aerial vehicle (UAV) is defined as a "powered, aerial vehicle that does not.

Unmanned aerial vehicle. carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload". UAV is a term that is commonly applied to military use cases. However missiles with warheads are not considered UAVs because the vehicle itself is a munition. Also, the relation of UAVs to remote controlled model aircraft is unclear, UAVs may or may not include remote-controlled model aircraft. Some jurisdictions base their definition on size or weight; however, the US FAA defines any uncrewed flying craft as a UAV.

Unmanned aerial vehicle. regardless of size. The term "unmanned aircraft system" (UAS) was adopted by the United States Department of Defense (DoD) and the United States Federal Aviation Administration (FAA) in 2005 according to their Unmanned Aircraft System Roadmap 2005–2030. The International Civil Aviation Organization (ICAO) and the British Civil Aviation Authority adopted this term, also used in the European Union's Single-European-Sky (SES) Air-Traffic-Management (ATM) Research (SESAR Joint Undertaking) roadmap for 2020. This term emphasizes the importance of elements other than the aircraft. It includes elements such as ground control stations, data links and other support equipment. A similar term is an "unmanned-aircraft.

Unmanned aerial vehicle. vehicle system" (UAVS), "remotely piloted aerial vehicle" (RPAV), "remotely piloted aircraft system" (RPAS). Many similar terms are in use. "Unoccupied" and "uninhabited" are occasionally used as alternatives to "unmanned". Under new regulations which came into effect 1 June 2019, the term RPAS (Remotely Piloted Aircraft System) has been adopted by the Canadian Government to mean "a set of configurable elements consisting of a remotely piloted aircraft, its control station, the command and control links and any other system elements required during flight operation".## Classification types.UAVs may be classified like any other aircraft, according to design configuration such as weight or.

Unmanned aerial vehicle. engine type, maximum flight altitude, degree of operational autonomy, operational role, etc. According to the United States Department of Defense, UAVs are classified into five categories below:Other classifications of UAVs include:## Range and endurance.There are usually five categories when UAVs are classified by range and endurance:## Size.There are usually four categories when UAVs are classified by size, with at least one of the dimensions (length or wingspan) meet the following respective limits:## Weight.Based on their weight, drones can be classified into five categories — nano (weighing up to 250 g), Micro air vehicles (MAV) (250 g – 2 kg), Miniature.

Unmanned aerial vehicle. UAV or small (SUAV) (2–25 kg), medium (25–150 kg), and large (over 150 kg).## Degree of autonomy.Drones could also be classified based on the degree of autonomy in their flight operations. ICAO classifies uncrewed aircraft as either remotely piloted aircraft or fully autonomous. Some UAVs offer intermediate degrees of autonomy. For example, a vehicle may be remotely piloted in most contexts but have an autonomous return-to-base operation. Some aircraft types may optionally fly manned or as UAVs, which may include manned aircraft transformed into uncrewed or Optionally Piloted UAVs (OPVs).## Altitude.Based on the altitude, the following UAV classifications have been.

Unmanned aerial vehicle. Carrier Guidance System (CACGS) for UAVs## Composite criteria.An example of classification based on the composite criteria is U.S. Military's unmanned aerial systems (UAS) classification of UAVs based on weight, maximum altitude and speed of the UAV component.## History.## Early drones.The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, with a balloon carrier (the precursor to the aircraft carrier) in the first offensive use of air power in naval aviation. Austrian forces besieging Venice attempted to launch some 200 incendiary balloons at the besieged city. The balloons were launched mainly from land; however, some were.

Unmanned aerial vehicle. also launched from the Austrian ship . At least one bomb fell in the city; however, due to the wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship "Vulcano".The Spanish engineer Leonardo Torres y Quevedo introduced a radio-based control-system called the "Telekino" at the Paris Academy of Science in 1903 with the intention of testing an airship of his own design without risking human lives.Significant development of drones started in the 1900s, and originally focused on providing practice targets for training military personnel. The earliest attempt at.

Unmanned aerial vehicle. a powered UAV was A. M. Low's "Aerial Target" in 1916. Low confirmed that Geoffrey de Havilland's monoplane was the one that flew under control on 21 March 1917 using his radio system. Following this successful demonstration in the spring of 1917 Low was transferred to develop aircraft controlled fast motor launches D.C.B.s with the Royal Navy in 1918 intended to attack shipping and port installations and he also assisted Wing Commander Brock in preparations for the Zeebrugge Raid. Other British unmanned developments followed, leading to the fleet of over 400 de Havilland 82 Queen Bee aerial targets that went.

Unmanned aerial vehicle. in the late 1930s.## World War II.In 1940 Denny started the Radioplane Company and more models emerged during World War II used both to train antiaircraft gunners and to fly attack-missions. Nazi Germany produced and used various UAV aircraft during the war, like the Argus As 292 and the V-1 flying bomb with a jet engine.## Postwar period.After World War II development continued in vehicles such as the American JB-4 (using television/radio-command guidance), the Australian GAF Jindivik and Teledyne Ryan Firebee I of 1951, while companies like Beechcraft offered their Model 1001 for the U.S. Navy in 1955. Nevertheless, they.

Unmanned aerial vehicle. were little more than remote-controlled airplanes until the Vietnam War.In 1959 the U.S. Air Force, concerned about losing pilots over hostile territory, began planning for the use of uncrewed aircraft. Planning intensified after the Soviet Union shot down a U-2 in 1960. Within days, a highly-classified UAV program started under the code name of "Red Wagon". The August 1964 clash in the Tonkin Gulf between naval units of the U.S. and the North Vietnamese Navy initiated America's highly-classified UAVs (Ryan Model 147, Ryan AQM-91 Firefly, Lockheed D-21) into their first combat missions of the Vietnam War. When the Chinese government.

Unmanned aerial vehicle. showed photographs of downed U.S. UAVs via "Wide World Photos", the official U.S. response was "no comment".During the War of Attrition (1967–1970) in the Middle East, Israeli intelligence tested the first tactical UAVs installed with reconnaissance cameras, which successfully returned photos from across the Suez Canal. This was the first time that tactical UAVs that could be launched and landed on any short runway (unlike the heavier jet-based UAVs) were developed and tested in battle.In the 1973 Yom Kippur War, Israel used UAVs as decoys to spur opposing forces into wasting expensive anti-aircraft missiles. After the 1973 Yom Kippur war,.

Unmanned aerial vehicle. a few key people from the team that developed this early UAV joined a small startup company that aimed to develop UAVs into a commercial product, eventually purchased by Tadiran and leading to the development of the first Israeli UAV.In 1973 the U.S. military officially confirmed that they had been using UAVs in Southeast Asia (Vietnam). Over 5,000 U.S. airmen had been killed and over 1,000 more were missing or captured. The USAF 100th Strategic Reconnaissance Wing flew about 3,435 UAV missions during the war at a cost of about 554 UAVs lost to all causes. In the words of.

Unmanned aerial vehicle. USAF General George S. Brown, Commander, Air Force Systems Command, in 1972, "The only reason we need (UAVs) is that we don't want to needlessly expend the man in the cockpit." Later that year, General John C. Meyer, Commander in Chief, Strategic Air Command, stated, "we let the drone do the high-risk flying ... the loss rate is high, but we are willing to risk more of them ...they save lives!"During the 1973 Yom Kippur War, Soviet-supplied surface-to-air missile-batteries in Egypt and Syria caused heavy damage to Israeli fighter jets. As a result, Israel developed the IAI Scout as the.

Unmanned aerial vehicle. first UAV with real-time surveillance. The images and radar decoys provided by these UAVs helped Israel to completely neutralize the Syrian air defenses at the start of the 1982 Lebanon War, resulting in no pilots downed. In Israel in 1987, UAVs were first used as proof-of-concept of super-agility, post-stall controlled flight in combat-flight simulations that involved tailless, stealth-technology-based, three-dimensional thrust vectoring flight-control, and jet-steering.## Modern UAVs.With the maturing and miniaturization of applicable technologies in the 1980s and 1990s, interest in UAVs grew within the higher echelons of the U.S. military. In the 1990s, the U.S. DoD gave a contract to.

Unmanned aerial vehicle. AAI Corporation along with Israeli company Malat. The U.S. Navy bought the AAI Pioneer UAV that AAI and Malat developed jointly. Many of these UAVs saw service in the 1991 Gulf War. UAVs demonstrated the possibility of cheaper, more capable fighting-machines, deployable without risk to aircrews. Initial generations primarily involved surveillance aircraft, but some carried armaments, such as the General Atomics MQ-1 Predator, that launched AGM-114 Hellfire air-to-ground missiles.CAPECON, a European Union project to develop UAVs, ran from 1 May 2002 to 31 December 2005. the United States Air Force (USAF) employed 7,494 UAVs almost one in three USAF aircraft.

Unmanned aerial vehicle. The Central Intelligence Agency also operated UAVs. By 2013 at least 50 countries used UAVs. China, Iran, Israel, Pakistan, Turkey, and others designed and built their own varieties. The use of drones has continued to increase. Due to their wide proliferation, no comprehensive list of UAV systems exists.The development of smart technologies and improved electrical-power systems led to a parallel increase in the use of drones for consumer and general aviation activities. As of 2021, quadcopter drones exemplify the widespread popularity of hobby radio-controlled aircraft and toys, however the use of UAVs in commercial and general aviation is limited by.

Unmanned aerial vehicle. a lack of autonomy and by new regulatory environments which require line-of-sight contact with the pilot.In 2020 a Kargu 2 drone hunted down and attacked a human target in Libya, according to a report from the UN Security Council's Panel of Experts on Libya, published in March 2021. This may have been the first time an autonomous killer-robot armed with lethal weaponry attacked human beings.Superior drone technology played a role in Azerbaijan's successes in the 2020 Nagorno-Karabakh war against Armenia.UAVs are also used in NASA missions. The Dragonfly spacecraft is being developed, and is aiming to reach and examine Saturn's.

Unmanned aerial vehicle. moon Titan. Its primary goal is to roam around the surface, expanding the amount of area to be researched previously seen by Landers. As a UAV, Dragonfly allows examination of potentially diverse types of soil. The drone is set to launch in 2027, and is estimated to take a seven more years to reach the Saturnian system.## Design.Crewed and uncrewed aircraft of the same type generally have recognizably similar physical components. The main exceptions are the cockpit and environmental control system or life support systems. Some UAVs carry payloads (such as a camera) that weigh considerably less than an adult.

Unmanned aerial vehicle. human, and as a result, can be considerably smaller. Though they carry heavy payloads, weaponized military UAVs are lighter than their crewed counterparts with comparable armaments.Small civilian UAVs have no life-critical systems, and can thus be built out of lighter but less sturdy materials and shapes, and can use less robustly tested electronic control systems. For small UAVs, the quadcopter design has become popular, though this layout is rarely used for crewed aircraft. Miniaturization means that less-powerful propulsion technologies can be used that are not feasible for crewed aircraft, such as small electric motors and batteries.Control systems for UAVs are.

Unmanned aerial vehicle. often different than crewed craft. For remote human control, a camera and video link almost always replace the cockpit windows; radio-transmitted digital commands replace physical cockpit controls. Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets.## Aircraft configuration.The primary difference from manned aeroplanes is the lack of need for a cockpit area and its windows. However some types are adapted from piloted examples, or are designed for optional piloted or unmanned operational modes. Air safety is also less of a critical requirement for unmanned aircraft, allowing the designer greater freedom to experiment. These two factors.

Unmanned aerial vehicle. have led to a great variety of airframe and engine configurations in UAVs.For conventional flight the flying wing and blended wing body offer light weight combined with low drag and stealth, and are popular configurations. Larger types which carry a variable payload are more likely to feature a distinct fuselage with a tail for stability, control and trim, although the wing configurations in use vary widely.For vertical flight, the tailless quadcopter requires a relatively simple control system and is common for smaller UAVs. However the mechanism does not scale well to larger aircraft, which tend to use a conventional single.

Unmanned aerial vehicle. rotor with collective and cyclic pitch control, along with a stabilising tail rotor.## Propulsion.Traditional internal combustion and jet engines remain in use for drones requiring long range. However for shorter-range missions electric power has almost entirely taken over. The distance record for a UAV (built from balsa wood and mylar skin) across the North Atlantic Ocean is held by a gasoline model airplane or UAV. Manard Hill "in 2003 when one of his creations flew 1,882 miles across the Atlantic Ocean on less than a gallon of fuel" holds this record.Besides the traditional piston engine, the Wankel rotary engine is.

Unmanned aerial vehicle. used by some drones. This type offers high power output for lower weight, with quieter and more vibration-free running. Claims have also been made for improved reliability and greater range.Small drones mostly use lithium-polymer batteries (Li-Po), while some larger vehicles have adopted the a hydrogen fuel cell. The energy density of modern Li-Po batteries is far less than gasoline or hydrogen. However electric motors are cheaper, lighter and quieter. Complex multi-engine, multi-propeller installations are under development with the goal of improving aerodynamic and propulsive efficiency. For such complex power installations, Battery elimination circuitry (BEC) may be used to centralize power.

Unmanned aerial vehicle. distribution and minimize heating, under the control of a microcontroller unit (MCU).## Ornithopters – wing propulsion.Flapping-wing ornithopters, imitating birds or insects, have been flown as microUAVs. Their inherent stealth recommends them for spy missions.Sub-1g microUAVs inspired by flies, albeit using a power tether, have been able to "land" on vertical surfaces. Other projects mimic the flight of beetles and other insects.## Computer control systems.UAV computing capability followed the advances of computing technology, beginning with analog controls and evolving into microcontrollers, then system-on-a-chip (SOC) and single-board computers (SBC).System hardware for small UAVs is often called the flight controller (FC), flight controller.

Unmanned aerial vehicle. board (FCB) or autopilot.## Architecture.## Sensors.Position and movement sensors give information about the aircraft state. Exteroceptive sensors deal with external information like distance measurements, while exproprioceptive ones correlate internal and external states.Non-cooperative sensors are able to detect targets autonomously so they are used for separation assurance and collision avoidance.Degrees of freedom (DOF) refers to both the amount and quality of sensors on board: 6 DOF implies 3-axis gyroscopes and accelerometers (a typical inertial measurement unit IMU), 9 DOF refers to an IMU plus a compass, 10 DOF adds a barometer and 11 DOF usually adds a GPS receiver.## Actuators.UAV actuators.

Unmanned aerial vehicle. include digital electronic speed controllers (which control the RPM of the motors) linked to motors/engines and propellers, servomotors (for planes and helicopters mostly), weapons, payload actuators, LEDs and speakers.## Software.UAV software called the flight stack or autopilot. The purpose of the flight stack is to obtain data from sensors, control motors to ensure UAV stability, and facilitate ground control and mission planning communication.UAVs are real-time systems that require rapid response to changing sensor data. As a result, UAVs rely on single-board computers for their computational needs. Examples of such single-board computers include Raspberry Pis, Beagleboards, etc. shielded with NavIO, PXFMini,.

Unmanned aerial vehicle. etc. or designed from scratch such as NuttX, preemptive-RT Linux, Xenomai, Orocos-Robot Operating System or DDS-ROS 2.0.Civil-use open-source stacks include: Agilicious (also open-source hardware) ArduCopter CrazyFlie KKMultiCopter MultiWii BaseFlight (forked from MultiWii) CleanFlight (forked from BaseFlight) BetaFlight (forked from CleanFlight) iNav (forked from CleanFlight) RaceFlight (forked from CleanFlight) OpenPilot dRonin (forked from OpenPilot) LibrePilot (forked from OpenPilot) TauLabs (forked from OpenPilot) Paparazzi PX4 autopilot DroneCode (Umbrella organization managing PX4 within the Linux Foundation)Due to the open-source nature of UAV software, they can be customized to fit specific applications. For example, researchers from the Technical University of Košice have replaced the.

Unmanned aerial vehicle. default control algorithm of the PX4 autopilot. This flexibility and collaborative effort has led to a large number of different open-source stacks, some of which are forked from others, such as CleanFlight, which is forked from BaseFlight and from which three other stacks are forked from.## Loop principles.UAVs employ open-loop, closed-loop or hybrid control architectures. Open loop This type provides a positive control signal (faster, slower, left, right, up, down) without incorporating feedback from sensor data. Closed loop This type incorporates sensor feedback to adjust behavior (reduce speed to reflect tailwind, move to altitude 300 feet). The PID controller is.

Unmanned aerial vehicle. common. Sometimes, feedforward is employed, transferring the need to close the loop further.## Communications.UAVs use a radio for control and exchange of video and other data. Early UAVs had only narrowband uplink. Downlinks came later. These bi-directional narrowband radio links carried command and control (C&C) and telemetry data about the status of aircraft systems to the remote operator.In most modern UAV applications, video transmission is required. So instead of having separate links for C&C, telemetry and video traffic, a broadband link is used to carry all types of data. These broadband links can leverage quality of service techniques and carry.

Unmanned aerial vehicle. TCP/IP traffic that can be routed over the Internet.The radio signal from the operator side can be issued from either: Ground control – a human operating a radio transmitter/receiver, a smartphone, a tablet, a computer, or the original meaning of a military ground control station (GCS). Remote network system, such as satellite duplex data links for some military powers. Downstream digital video over mobile networks has also entered consumer markets, while direct UAV control uplink over the cellular mesh and LTE have been demonstrated and are in trials. Another aircraft, serving as a relay or mobile control station military manned-unmanned.

Unmanned aerial vehicle. teaming (MUM-T).Modern networking standards have explicitly considered drones and therefore include optimizations. The 5G standard has mandated reduced user plane latency to 1ms while using ultra-reliable and low-latency communications.## Autonomy.The level of autonomy in UAVs varies widely. UAV manufacturers often build in specific autonomous operations, such as: Self-level: attitude stabilization on the pitch and roll axes. Altitude hold: The aircraft maintains its altitude using barometric pressure and/or GPS data. Hover/position hold: Keep level pitch and roll, stable yaw heading and altitude while maintaining position using GNSS or inertial sensors. Headless mode: Pitch control relative to the position of the pilot.

Unmanned aerial vehicle. Performance considerations.## Flight envelope.UAVs can be programmed to perform aggressive maneuvers or landing/perching on inclined surfaces, and then to climb toward better communication spots. Some UAVs can control flight with varying flight modelisation, such as VTOL designs.UAVs can also implement perching on a flat vertical surface.## Endurance.UAV endurance is not constrained by the physiological capabilities of a human pilot.Because of their small size, low weight, low vibration and high power to weight ratio, Wankel rotary engines are used in many large UAVs. Their engine rotors cannot seize; the engine is not susceptible to shock-cooling during descent and it does not.

Unmanned aerial vehicle. require an enriched fuel mixture for cooling at high power. These attributes reduce fuel usage, increasing range or payload.Proper drone cooling is essential for long-term drone endurance. Overheating and subsequent engine failure is the most common cause of drone failure.Hydrogen fuel cells, using hydrogen power, may be able to extend the endurance of small UAVs, up to several hours.Micro air vehicles endurance is so far best achieved with flapping-wing UAVs, followed by planes and multirotors standing last, due to lower Reynolds number.Solar-electric UAVs, a concept originally championed by the AstroFlight Sunrise in 1974, have achieved flight times of several weeks.Solar-powered.

Unmanned aerial vehicle. atmospheric satellites ("atmosats") designed for operating at altitudes exceeding 20 km (12 miles, or 60,000 feet) for as long as five years could potentially perform duties more economically and with more versatility than low Earth orbit satellites. Likely applications include weather monitoring, disaster recovery, Earth imaging and communications.Electric UAVs powered by microwave power transmission or laser power beaming are other potential endurance solutions.Another application for a high endurance UAV would be to "stare" at a battlefield for a long interval (ARGUS-IS, Gorgon Stare, Integrated Sensor Is Structure) to record events that could then be played backwards to track battlefield activities.##.

Unmanned aerial vehicle. Reliability.Reliability improvements target all aspects of UAV systems, using resilience engineering and fault tolerance techniques.Individual reliability covers robustness of flight controllers, to ensure safety without excessive redundancy to minimize cost and weight. Besides, dynamic assessment of flight envelope allows damage-resilient UAVs, using non-linear analysis with ad hoc designed loops or neural networks. UAV software liability is bending toward the design and certifications of crewed avionics software.Swarm resilience involves maintaining operational capabilities and reconfiguring tasks given unit failures.## Applications.In recent years, autonomous drones have begun to transform various application areas as they can fly beyond visual line of sight (BVLOS) while.

Unmanned aerial vehicle. maximizing production, reducing costs and risks, ensuring site safety, security and regulatory compliance, and protecting the human workforce in times of a pandemic. They can also be used for consumer-related missions like package delivery, as demonstrated by Amazon Prime Air, and critical deliveries of health supplies.There are numerous civilian, commercial, military, and aerospace applications for UAVs. These include:General: Recreation, Disaster relief, archeology, conservation of biodiversity and habitat, law enforcement, crime, and terrorism. Commercial: Aerial surveillance, filmmaking, journalism, scientific research, surveying, cargo transport, mining, manufacturing, Forestry, solar farming, thermal energy, ports and agriculture.## Warfare.With extensive cost reductions and advancements in the.

Unmanned aerial vehicle. UAVs technology, the defense forces around the globe are increasingly using these for various applications such as surveillance, logistics, communication, attack and combat.As of 2020, seventeen countries have armed UAVs, and more than 100 countries use UAVs in a military capacity. The global military UAV market is dominated by companies based in the United States, Turkey, China, Israel and Iran. By sale numbers, the US held over 60% military-market share in 2017. Top military UAV manufactures are including General Atomics, Lockheed Martin, Northrop Grumman, Boeing, Baykar, TAI, IAIO, CASC and CAIG. China has established and expanded its presence in military.

Unmanned aerial vehicle. UAV market since 2010. Turkey also established and expanded its presence in military UAV market.Of the 18 countries that are known to have received military drones between 2010 to 2019, the top 12 all purchased their drones from China. According to a report of 2015, Israeli companies mainly focus on small surveillance UAV systems and by quantity of drones, Israel exported 60.7% (2014) of UAV on the market while the United States export 23.9% (2014). Between 2010 and 2014, there were 439 drones exchanged compared to 322 in the five years previous to that, among these only small fraction of.

Unmanned aerial vehicle. overall trade – just 11 (2.5%) of the 439 are armed drones. The US alone operated over 9,000 military UAVs in 2014; among them more than 7000 are RQ-11 Raven miniature UAVs. General Atomics is the dominant manufacturer with the Global Hawk and Predator/Mariner systems product-line.For intelligence and reconnaissance missions, the inherent stealth of micro UAV flapping-wing ornithopters, imitating birds or insects, offers potential for covert surveillance and makes them difficult targets to bring down.UAVs are used for reconnaissance, attack, demining, and target practice.## Civil.The civilian (commercial and general) drone market is dominated by Chinese companies. Chinese drone manufacturer DJI.

Unmanned aerial vehicle. alone had 74% of the civil market share in 2018, with no other company accounting for more than 5%, and with $11 billion forecast global sales in 2020. Following increased scrutiny of its activities, the US Interior Department grounded its fleet of DJI drones in 2020, while the Justice Department prohibited the use of federal funds for the purchase of DJI and other foreign made UAVs. DJI is followed by Chinese company Yuneec, US company 3D Robotics and French company Parrot with a significant gap in market share. As of May 2021, 873,576 UAVs have been registered with the US.

Unmanned aerial vehicle. FAA, of which 42% are categorized as commercial drones and 58% as recreational drones. 2018 NPD point to consumers increasingly purchasing drones with more advanced features with 33 percent growth in both the $500+ and $1000+ market segments.The civil UAV market is relatively new compared to the military one. Companies are emerging in both developed and developing nations at the same time. Many early stage startups have received support and funding from investors as is the case in the United States and by government agencies as is the case in India. Some universities offer research and training programs or degrees.

Unmanned aerial vehicle. Private entities also provide online and in-person training programs for both recreational and commercial UAV use.Consumer drones are also widely used by military organizations worldwide because of the cost-effective nature of consumer product. In 2018, Israeli military started to use DJI Mavic and Matrice series of UAV for light reconnaissance mission since the civil drones are easier to use and have higher reliability. DJI drones is also the most widely used commercial unmanned aerial system that the US Army has employed. DJI surveillance drones have also been used by Chinese police in Xinjiang since 2017.The global UAV market will reach.

Unmanned aerial vehicle. US$21.47 billion, with the Indian market touching the US$885.7 million mark, by 2021.Lighted drones are beginning to be used in nighttime displays for artistic and advertising purposes.## Aerial photography.Drones are ideally suited to capturing aerial shots in photography and cinematography, and are widely used for this purpose. Small drones avoid the need for precise coordination between pilot and cameraman, with the same person taking on both roles. However, big drones with professional cine cameras, there is usually a drone pilot and a camera operator who controls camera angle and lens. For example, the AERIGON cinema drone which is used in.

Unmanned aerial vehicle. film production in big blockbuster movies is operated by 2 people. Drones provide access to dangerous, remote or otherwise inaccessible sites.## Agriculture and forestry.As global demand for food production grows exponentially, resources are depleted, farmland is reduced, and agricultural labor is increasingly in short supply, there is an urgent need for more convenient and smarter agricultural solutions than traditional methods, and the agricultural drone and robotics industry is expected to make progress. Agricultural drones have been used in areas such as Africa to help build sustainable agriculture.The use of UAVs is also being investigated to help detect and fight wildfires,.

Unmanned aerial vehicle. whether through observation or launching pyrotechnic devices to start backfires.## Law enforcement.Police can use drones for applications such as search and rescue and traffic monitoring.## Safety and security.## Threats.## Nuisance.UAVs can threaten airspace security in numerous ways, including unintentional collisions or other interference with other aircraft, deliberate attacks or by distracting pilots or flight controllers. The first incident of a drone-airplane collision occurred in mid-October 2017 in Quebec City, Canada. The first recorded instance of a drone collision with a hot air balloon occurred on 10 August 2018 in Driggs, Idaho, United States; although there was no significant damage to.

Unmanned aerial vehicle. the balloon nor any injuries to its 3 occupants, the balloon pilot reported the incident to the National Transportation Safety Board, stating that "I hope this incident helps create a conversation of respect for nature, the airspace, and rules and regulations". Unauthorized UAV flights into or near major airports have prompted extended shutdowns of commercial flights.Drones caused significant disruption at Gatwick Airport during December 2018, needing the deployment of the British Army.In the United States, flying close to a wildfire is punishable by a maximum $25,000 fine. Nonetheless, in 2014 and 2015, firefighting air support in California was hindered on.

Unmanned aerial vehicle. several occasions, including at the Lake Fire and the North Fire. In response, California legislators introduced a bill that would allow firefighters to disable UAVs which invaded restricted airspace. The FAA later required registration of most UAVs.## Security vulnerabilities.By 2017, drones were being used to drop contraband into prisons.The interest in UAVs cyber security has been raised greatly after the Predator UAV video stream hijacking incident in 2009, where Islamic militants used cheap, off-the-shelf equipment to stream video feeds from a UAV. Another risk is the possibility of hijacking or jamming a UAV in flight. Several security researchers have made.

Unmanned aerial vehicle. public some vulnerabilities in commercial UAVs, in some cases even providing full source code or tools to reproduce their attacks. At a workshop on UAVs and privacy in October 2016, researchers from the Federal Trade Commission showed they were able to hack into three different consumer quadcopters and noted that UAV manufacturers can make their UAVs more secure by the basic security measures of encrypting the Wi-Fi signal and adding password protection.## Aggression.UAVs could be loaded with dangerous payloads, and crashed into vulnerable targets. Payloads could include explosives, chemical, radiological or biological hazards. UAVs with generally non-lethal payloads could possibly.

Unmanned aerial vehicle. be hacked and put to malicious purposes. Anti-UAV systems are being developed by states to counter this threat. This is, however, proving difficult. As Dr J. Rogers stated in an interview to A&T "There is a big debate out there at the moment about what the best way is to counter these small UAVs, whether they are used by hobbyists causing a bit of a nuisance or in a more sinister manner by a terrorist actor".## Countermeasures.## Counter unmanned air system.The malicious use of UAVs has led to the development of counter unmanned air system (C-UAS) technologies. Automatic tracking and.

Unmanned aerial vehicle. detection of UAVs from commercial cameras have become accurate thanks to the development of deep learning based machine learning algorithms. It is also possible to automatically identify UAVs across different cameras with different view points and hardware specification with re-identification methods.

Pro Football Hall of Fame. The Pro Football Hall of Fame is the hall of fame for professional American football, located in Canton, Ohio. Opened on September 7, , the Hall of Fame enshrines exceptional figures in the sport of professional football, including players, coaches, officials, franchise owners, and front-office personnel, almost all of whom made their primary contributions to the game in the National Football League (NFL).As of the Class of 2022, there are a total of 362 members of the Hall of Fame. Between four and eight new inductees are normally enshrined every year. For the 2020 class, a 20-person group consisting of.

Hexagon. of the circumscribed circle or circumcircle, which equals formula_1 times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has six rotational symmetries ("rotational symmetry of order six") and six reflection symmetries ("six lines of symmetry"), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side. From this it can be seen that a triangle with a vertex at the center of the regular hexagon and sharing one side with the hexagon is equilateral, and that the regular hexagon.

Hexagon. adding alternating squares and equilateral triangles around it. This pattern repeats within the rhombitrihexagonal tiling.## Self-crossing hexagons.There are six self-crossing hexagons with the vertex arrangement of the regular hexagon:## Hexagonal structures.From bees' honeycombs to the Giant's Causeway, hexagonal patterns are prevalent in nature due to their efficiency. In a hexagonal grid each line is as short as it can possibly be if a large area is to be filled with the fewest hexagons. This means that honeycombs require less wax to construct and gain much strength under compression.Irregular hexagons with parallel opposite edges are called parallelogons and can also tile.

Hexagon. the plane by translation. In three dimensions, hexagonal prisms with parallel opposite faces are called parallelohedrons and these can tessellate 3-space by translation.## Tesselations by hexagons.In addition to the regular hexagon, which determines a unique tessellation of the plane, any irregular hexagon which satisfies the Conway criterion will tile the plane.## Hexagon inscribed in a conic section.Pascal's theorem (also known as the "Hexagrammum Mysticum Theorem") states that if an arbitrary hexagon is inscribed in any conic section, and pairs of opposite sides are extended until they meet, the three intersection points will lie on a straight line, the "Pascal line.

Hexagon. of that configuration.## Cyclic hexagon.The Lemoine hexagon is a cyclic hexagon (one inscribed in a circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point.If the successive sides of a cyclic hexagon are "a", "b", "c", "d", "e", "f", then the three main diagonals intersect in a single point if and only if .If, for each side of a cyclic hexagon, the adjacent sides are extended to their intersection, forming a triangle exterior to the given side, then the segments.

Hexagon. connecting the circumcenters of opposite triangles are concurrent.If a hexagon has vertices on the circumcircle of an acute triangle at the six points (including three triangle vertices) where the extended altitudes of the triangle meet the circumcircle, then the area of the hexagon is twice the area of the triangle.## Hexagon tangential to a conic section.Let ABCDEF be a hexagon formed by six tangent lines of a conic section. Then Brianchon's theorem states that the three main diagonals AD, BE, and CF intersect at a single point.In a hexagon that is tangential to a circle and that has consecutive sides.

The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes.A regular skew hexagon is vertex-transitive with equal edge lengths. In three dimensions it will be.

Common brushtail possum. The common brushtail possum (Trichosurus vulpecula, from the Greek for "furry tailed" and the Latin for "little fox", previously in the genus "Phalangista") is a nocturnal, semiarboreal marsupial of the family Phalangeridae, native to Australia and naturalised in New Zealand, and the second-largest of the possums.Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats. In most Australian habitats, eucalyptus leaves are a significant part of the diet, but rarely the sole item eaten.

It is found throughout the eastern and northern parts of the continent, as well as some western regions, Tasmania and a number of offshore islands, such as Kangaroo Island and Barrow Island. It is also widespread in New Zealand since its introduction in 1850. The common brushtail possum can be found in a variety of habitats, such as forests, semi-arid areas and even cultivated or urban areas. It is mostly a forest inhabiting species, however it is also found in treeless areas. In New.

Common brushtail possum. Zealand, possums favour broadleaf-podocarp near farmland pastures. In southern beech forests and pine plantations, possums are less common. Overall, brushtail possums are more densely populated in New Zealand than in their native Australia. This may be because Australia has more fragmented eucalypt forests and more predators. In Australia, brushtail possums are threatened by humans, tiger quolls, dogs, foxes, cats, goannas, carpet snakes, and powerful owls. In New Zealand, brushtail possums are threatened only by humans and cats. The IUCN highlight the population trend in Australia as decreasing.## Food and foraging.The common brushtail possum can adapt to numerous kinds of vegetation.

Common brushtail possum. New Zealand use many more den sites than those from Australia. Brushtail possums compete with each other and other animals for den spaces, and this contributes to their mortality. This is likely another reason why brushtail possum population densities are smaller in Australia than in New Zealand. Brushtail possums are usually not aggressive towards each other and usually just stare with erect ears. They vocalise with clicks, grunts, hisses, alarm chatters, guttural coughs, and screeching.## Reproduction and life history.The common brushtail possum can breed at any time of the year, but breeding tends to peak in spring, from September to.

In one Queensland population, males apparently need a month of consorting with females before they can mate with them. Females have a gestation period of 16–18 days, after which they give birth to single young. A newborn brushtail possum is only 1.5 cm long and weighs only 2 g. As usual for marsupials, the newborn may climb, unaided, through the female's fur and into the pouch and attach to a.

In New Zealand's Ōrongorongo population, female young have been found to continue to associate with their mothers after weaning, and some inherit the prime den sites. A possible competition exists between mothers and daughters for dens, and daughters may be excluded from a den occupied by the mother. In forests with shortages of den sites, females apparently produce more sons, which do not compete directly for den sites, while in forests with plentiful den sites, female young are greater in number.## Relationship with humans.The common brushtail possum is considered a pest in some.

Like other possums, it is rather tolerant of humans and can sometimes be hand fed, although it is not encouraged, as their claws are quite sharp and can cause infection or disease to humans if scratched. It is a traditional food source for some indigenous Australians.## Australia.Its fur has been considered valuable and has been harvested.

Puffbird. The puffbirds and their relatives in the near passerine family Bucconidae are tropical tree-dwelling insectivorous birds that are found from South America up to Mexico. Together with their closest relatives, the jacamars, they form a divergent lineage within the order Piciformes, though the two families are sometimes elevated to a separate order Galbuliformes. Lacking the iridescent colours of the jacamars, puffbirds are mainly brown, rufous or grey, with large heads, large eyes, and flattened bills with a hooked tip. Their loose, abundant plumage and short tails makes them look stout and puffy, giving rise to the English name of the.

Puffbird. puffbird and jacamar lineage was in question, with some bone and muscle features suggesting they may be more closely related to the Coraciiformes. However, analysis of nuclear DNA in a 2003 study placed them as sister group to the rest of the Piciformes, also showing that the groups had developed zygodactyl feet (two toes facing forward and two aft) before separating.

Mango. A mango is an edible stone fruit produced by the tropical tree "Mangifera indica". It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. "M. indica" has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus "Mangifera" also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion.Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size,.

Masticophis flagellum. Masticophis flagellum is a species of nonvenomous colubrid snake, commonly referred to as the coachwhip or the whip snake, which is endemic to the United States and Mexico. Six subspecies are recognized, including the nominotypical subspecies.## Taxonomy.## Etymology.The subspecific name, "ruddocki", is in honor of Dr. John C. Ruddock who was Medical Director for the Richfield Oil Corporation.## Subspecies.Six subspecies of "Masticophis flagellum" are recognized as being valid, including the nominotypical subspecies."Masticophis flagellum cingulum" – Sonoran coachwhip"Masticophis flagellum flagellum" – eastern coachwhip"Masticophis flagellum lineatulus" – lined coachwhip"Masticophis flagellum piceus" – red coachwhip, red racer"Masticophis flagellum ruddocki" – San Joaquin coachwhip"Masticophis.

They vary greatly in color, but most reflect a proper camouflage for their natural habitat. "M. f. testaceus" is typically a shade of light brown with darker brown flecking, but in the western area of Texas, where the soil color is a shade of pink, the coachwhips are also pink in color. "M. f. piceus" was given its common name because specimens frequently,.

Masticophis flagellum. but not always, have some red in their coloration. Coachwhip scales are patterned so at first glance, the snake appears braided. Subspecies can be difficult to distinguish in areas where their ranges overlap. Adult sizes of 127 - 183 (cm) in total length (including tail) are common. The record sized specimen, of the eastern coachwhip race, was 259 (cm) in total length. Young specimens, mostly just over 100 (cm) in length, were found to have weighed 180 to 675 (g), whereas good-sized mature adults measuring 163 to 235 (cm) weighed 1.2 to 1.8 (kg).## Distribution and habitat.Coachwhips range throughout the.

Masticophis flagellum. southern United States from coast to coast. They are also found in the northern half of Mexico.Coachwhips are commonly found in open areas with sandy soil, open pine forests, old fields, and prairies. They thrive in sandhill scrub and coastal dunes.## Behavior.Coachwhips are diurnal, and actively hunt and eat lizards, small birds, and rodents. Coachwhips subdue prey by grasping and holding them with their jaws and do not use constriction. They tend to be sensitive to potential threats, and often bolt at the first sign of one, and will readily strike if cornered. Their bites can be painful, but generally.

Masticophis flagellum. are harmless unless they become infected, as is the case with any wound. They are curious snakes with good eyesight, and are sometimes seen raising their heads above the level of the grass or rocks to see what is around them. They are extremely fast-moving snakes, able to move up to 4 miles per hour.## Myths.The primary myth concerning coachwhips, that they chase people, likely arises from the snake and the person both being frightened, and both just happening to be going the same way to escape. Coachwhips are fast snakes, often moving faster than a human, and thus give.

Masticophis flagellum. an impression of aggression should they move toward the person.The legend of the hoop snake may refer to the coachwhip snakes.Another myth of the rural southeastern United States is of a snake that, when disturbed, would chase a person down, wrap him up in its coils, whip him to death with its tail, and then make sure he is dead by sticking its tail up the victim's nose to see if he is still breathing. In actuality, coachwhips are neither constrictors (snakes that dispatch their prey by suffocating with their coils) nor strong enough to overpower a person. Also, they.

Masticophis flagellum. do not whip with their tails, even though their tails are long and look very much like a whip.In parts of Mexico, where ranching is a way of life, these snakes are believed to wrap around the legs of cows and feed on their milk as if suckling leaving the nipple dry. They will also hook on any other mammal that produces milk, leaving the young baby dehydrated.Ranchers also tell stories of "chirrioneras", which hypnotize women then latch onto their breasts to feed. If the woman has a crying hungry baby, the snake sticks its tail in the baby's mouth.

This leaves the baby malnourished and getting weaker while the mother can't feed her baby because her breasts have been sucked dry. The story goes that the only way to know if the snake has been there is if the baby has sores around the mouth.In 1888, a farmer near Orlando, Florida is said to have seen a sixteen foot coachwhip with a head four inches wide.

The Confederation Bridge () is a box girder bridge carrying the Trans-Canada Highway across the Abegweit Passage of the Northumberland Strait, linking the province of Prince Edward Island with the province of New Brunswick on the mainland. Opened May 31, 1997, the 12.9 (km) bridge is Canada's longest bridge and the world's longest bridge over ice-covered water.Construction took place from October 1993 to May 1997 and cost C$1.3 billion. Before its official naming, Prince Edward Islanders often referred to the bridge as the "Fixed Link". It officially opened to traffic on May 31, 1997. In April 2022, the PEI legislature.

Confederation Bridge. was at the 13 (km) wide Abegweit Passage. Infrequent winter service provided by underpowered steamships incapable of breaking sea ice ensured the survival of a passenger and mail service across Abegweit Passage using iceboats until a permanent ferry service was established in the 1910s.The unsatisfactory winter steamship service and reliance upon primitive iceboats provoked complaints from the Island government until the federal government decided to implement a railcar ferry service across Abegweit Passage between new ports at Port Borden and Cape Tormentine.In 1912, the federal government promised to open a car ferry between the "Capes" (Cape Traverse, PEI to Cape.

Confederation Bridge. (1969–1973) "Holiday Island" (1971–1997) "Vacationland" (1971–1997) "Abegweit" (1982–1997)## Early proposals.Discussion of a fixed link can be traced to George Howlan, who called for construction of a railway tunnel beneath Abegweit Passage at the same time as the Prince Edward Island Railway was being built across the province in the 1870s. Howlan also raised the issue as a member of the provincial Legislative Assembly, and in 1891, as a Senator and member of a delegation to meetings on the subject, conducted at the British Parliament. The idea lost favour following his death in 1901.Talk of a fixed link was revived in.

Confederation Bridge. the 1950s and 1960s, coinciding with federal election campaigns. The topic was raised in 1957, only two years following the opening of the Canso Causeway, and at the same time as another mega-project, the St. Lawrence Seaway was being constructed. A rockfill causeway was proposed to cross Abegweit Passage, with a 300 (m) bridge/tunnel to accommodate shipping. This plan was rejected for navigational reasons but was raised again in 1962, and in 1965, the federal government, ignoring concerns of the shipping industry, called for tenders for a $148 million fixed link featuring a tunnel/causeway/bridge. Approach roads and railway lines were.

Confederation Bridge. constructed at Borden and Jourimain Island but the project was formally abandoned in 1969 upon scientific recommendation in favour of improved ferry services.Due to the extremely complex tidal regime in the Northumberland Strait consisting of diurnal and semi-diurnal cycles, any attempt to close Abegweit Passage would be next to impossible since the tidal cycles on each side of a causeway would be placed at opposites to each other. It is estimated by tidal experts at the Canadian Hydrographic Service, that tidal currents through a gap in such a causeway would be in excess of 18 (kn), powerful enough to counter.

Confederation Bridge. fabrication to storage, and onto a nearby pier. These crawler transports, using specially designed teflon-coated concrete rails, earned the nickname "lobsters" from workers.All major components were lifted from the Amherst Head staging facility, transported, and placed in Abegweit Passage using the HLV "Svanen", a Dutch-built heavy lift catamaran, which during the construction of the fixed link was reportedly the tallest man-made structure in the province. HLV "Svanen" was custom-built for use on the Great Belt Bridge in the early 1990s, Denmark's largest construction project, and was modified at a French shipyard before working on the Northumberland Strait Crossing Project. Following.

Confederation Bridge. the placement of the final major component and completion of the bridge structure in Abegweit Passage on November 19, 1996, HLV "Svanen" returned to Denmark for use in construction of the Øresund Bridge.Construction of the fixed link required over 5,000 workers ranging from labourers and specialty trades, to engineers, surveyors, and managers. The economic impact of construction on Prince Edward Island was substantial, with the provincial GDP rising over 5% during the construction, providing a short-term economic boom for the Island.It neared completion in April 1997.## Naming.Throughout construction, the federal government received suggestions for names. A committee was formed on.

Confederation Bridge. May 1, 1996, chaired by former PEI Premier Alex Campbell, to choose the new name from the submissions. The committee chose the name "Abegweit Crossing", which would pay homage to the Abegweit Passage which the bridge crosses, the vessel M/V "Abegweit" which the bridge would replace, and to the Mi'kmaq traditional name for the island.However, the Canadian government overruled the committee, and on September 27, 1996, the Minister of Public Works and Government Services Diane Marleau announced that the bridge's name would be "Confederation Bridge". This name is not without controversy as many Islanders feel the word "Confederation" is overused.

Pūriri moth. The pūriri moth (Aenetus virescens), also commonly called the ghost moth or pepetuna, is a species of moth of the family Hepialidae. This moth is endemic to the North Island of New Zealand. It is New Zealand's largest moth, with a wingspan of up to 150 mm. It spends the first five to six years of its life as a grub in a tree trunk (common host plants are the pūriri tree ("Vitex lucens") and putaputāwētā ("Carpodetus serratus)", but pūriri larva also inhabit non-native species such as "Eucalyptus"), with the last 48 hours of its life as a moth.

Texas river cooter. The Texas river cooter ("Pseudemys texana") is a species of freshwater turtle endemic to the U.S. state of Texas. It is found in the river basins of the Brazos, San Bernard, Colorado, Guadalupe, San Antonio, Nueces, and their tributaries. It is one of three species of cooters ("Pseudemys") occurring in Texas, including the Rio Grande cooter ("Pseudemys gorzugi") and the river cooter ("Pseudemys concinna").## Description.The Texas river cooter is a relatively large turtle, capable of growing to a shell length of 12+ inches (30.5 cm). They are green in color, with yellow and black markings that fade with age. Males.

Texas river cooter. can be distinguished from females by their longer tails, longer claws, and overall smaller size.## Taxonomy.The Texas cooter was once reclassified to a subspecies of the eastern cooter, "Pseudemys concinna", but was given full species status in 1991.## Similar species.The red-eared slider ("Trachemys scripta elegans") shares its range and habits, but can easily be distinguished from the Texas cooter by red patches on either side of its head. Various species of map turtle can also look much like juvenile Texas cooters.Chelonia.org: "Pseudemys" care.

Bombus impatiens. Bombus impatiens, the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. Because of their great adaptability, they can live in country, suburbs, and even urban cities. This adaptability makes them a great pollinator species, leading to an increase in their commercial use by greenhouse industry. This increase consequently led to their farther spread outside their previous distribution range. They are considered one of the most important species of pollinator bees.

Bombus impatiens. in North America.## Taxonomy and phylogeny.The generic epithet (the first part of the name) "Bombus" comes from the genus "Bombus", which is also commonly known as bumblebee and belongs to the tribe "Bombini". The specific name (the latter half of its scientific name) may come from the flowers of the genus "Impatiens," which is one of its food sources"." An alternative explanation is that these bees are easily provoked into stinging, and so are "impatient."Including "B. impatiens," the genus "Bombus" contains 250 species and most species are characterized by their eusociality or parasitic nature. Specifically, the genus "Bombus" has 49.

Bombus impatiens. subgenera, and "B. impatiens" belongs to the subgenus "Pyrobombus". "B. impatiens" is also of the order Hymenoptera and family Apidae which characterizes its kin selection and relatedness.## Description and Identification.## Queens, workers, and males.The bees of "B. impatiens" are similar to those of "B. bimaculatus", "B. perplexus", "B. vagans", "B. sandersoni", and "B. separatus" in their appearance. They have short and even hair, medium-sized heads with cheeks that are similar in width to their heads, and a long and rectangular body. In general, queens and workers are similar in their coloring, pubescence, and structure. However, with a body length of.

Bombus impatiens. 17–23 mm, queens have bigger bodies than males or workers. Workers have bodies that are 8.5–16 mm, and males have bodies that are 12–18 mm long. The differences in their sizes can be observed by the differences in their larval weight at second instar. In addition to the difference in their sizes, males slightly differ in their coloring. While queens and workers are both black with a yellow thorax and first abdominal segment, males have a yellow face and head.## Nests."B. impatiens" have underground nests that are 1–3 feet below the ground surface. They enter their nests using tunnels that.

Bombus impatiens. are 18 inches to 9 feet long. Unlike the nests of honeybees or paper wasps, the nests of "B. impatiens" do not have a predictable pattern. The bees lay egg clumps all over inside the nest instead of having one brood area around which the workers’ distribution center is arranged.Within the nest there is a special division of labor and social organization. 11–13% of workers maintain small spatial fidelity zones inside the nest, and all workers remain at a specific distance from the colony center. Smaller individuals maintained smaller spatial zones and tended to be closer to the center of.

Bombus impatiens. the nest. Individuals that perform the in-nest task of larval feeding were found in the center of the nest, while foragers were often found on the periphery of the nest when not foraging.## Distribution and habitat.Broadly, they can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. More specifically, its range includes Ontario, the New England States, Georgia, Mississippi, Kentucky, Tennessee, Alabama, Maryland, Delaware, New Jersey, New York, Pennsylvania, South Carolina, North Carolina, Virginia, West Virginia, south to Florida, west to Michigan, Illinois, Kansas, Missouri, and Iowa. Also, the.

Bombus impatiens. increase in their commercial use by greenhouse industry led to the spread of the species outside its previous distribution range. "Bombus impatiens" adapts well to a variety of habitats, nectar sources, and climates and was seen visiting a variety and abundance of plants. In addition to agricultural, wetland, and urban conditions, the species can thrive in wooded habitats, and is likely related to woodland spring ephemerals. It nests underground in open fields and woods.## Colony.To start colonies, the gynes usually leave their hibernacula starting in mid-April and establish colonies in May. In the beginning of June, the workers start to.

Bombus impatiens. emerge and in August and September the male bees and young queens start appearing. However, at times, the bees can emerge around late to mid-October. In terms of colony sizes, a colony of "B. impatiens" consists of more than 450 individual bees and most are worker bees.## Behavior.## Division of labor.Inside the nest, the worker bees distribute themselves in a non-random fashion to be a certain distance away from the center of the nest. By doing so they increase their efficiency, as the distance traveled between tasks is minimized. The tasks of some workers are related to their space in.

Bombus impatiens. the nest. The labor for the workers is divided according to their body sizes. They vary in size, and the smaller bees are usually found near the center of the nest with the job of feeding the larvae whereas the bigger workers are usually found at the periphery, working as foragers and as guards. In general, they keep their spatial pattern as well as their jobs throughout their lifetime.## Reproductive suppression.Worker bees are totipotent and have the ability to lay eggs, and a few workers even have mature oocytes in their ovaries. However, when there is a queen in the.

Bombus impatiens. colony, the workers do not attempt to lay eggs or develop eggs. They usually do not show aggression towards other workers or the queen, showing no “competition phase.” Without a queen, aggression is more common.## Mating.A gyne mates with a male bee near the end of the hive's life cycle. They rest on the ground or on vegetation in order to mate and the mating lasts from 10 to 80 minutes. In order to increase the probability of his genes getting passed down safely, the male mates for a certain amount of time to let his sperm harden during mating.

Bombus impatiens. Soon thereafter the gynes hibernate. The following spring they emerge from hibernation and set about to get strong on nectar and to find a suitable old mouse or chipmunk hole to begin a colony. The first thing she builds is a honeypot, then she fills it with food (nectar/pollen), making it easier to feed her new brood, which are raised in paper cells she builds. The queens lay about 2000 eggs in one season, but only half of them will survive to become full adults.## Foraging.## Traplining.Foragers of "B. impatiens" colonies use a strategy called traplining, in which the bees.

Bombus impatiens. visit their food sources in a repeatable sequence, to improve their efficiency, especially in an unfamiliar environment. The bees establish traplines by searching among flowers in an orderly manner. Upon establishment, the traplines remain stable for long periods of time. Traplining has many advantages. The bees can minimize both the distance traveled by linking the sources in a more direct path and the time spent searching by knowing the locations of food sources. Also, the bees can travel through the locations that were recently depleted of their resources, saving their energy and time.## Communication."B. impatiens" use communication in order to.

Bombus impatiens. maximize the benefit of foraging. The bees become faster and more accurate as they become more experienced at foraging, and the returning foragers tend to stimulate the foraging activity of the colony. The foragers of "B. impatiens" improve their foraging activity by communicating with others in their nests. They share their abilities to associate scents of good food sources.## Interaction with other species.## Diet.There are many food plants for "B. impatiens" including: “"Aster"”, "Cirsium, Eupatorium, Gelsemium, Malus, Pontederia, Rubus, Solidago, Trifolium, Crocus, Pieris, Rhododendron", barberry, mountain laurel, rose, clover, purple vetch, pickerel weed, purple loosestrife, buttonbush, Beggar’s ticks, goldenrod, boneset,.

Bombus impatiens. burdock, and "Impatiens" from which the bee's name may come. The bees can eat the raw materials like pollen and nectar of the flowers but most bees in the colony eat honey that is made using the raw materials since it has higher nutritional value. To create honey, the bees consume the pollen and the nectar, and then regurgitate them, mixing them with enzymes in their stomachs.## Parasites."Bombus impatiens" are hosts to other bees. "Ps. Laborious" and "Bombus citrinus" are some examples of parasites. Also, Entromopox-like viruses and prokaryotes called Spiroplasmataceae have been found in the workers. However, there is.

Bombus impatiens. no known harmful effect to "B. impatiens".## Importance to humans.Bees play in a significant role in pollinating crops. A decline in bee population leads to a decline in crop yield, which will then result in a reduction in the food supply and cause economic hardships for farmers. Commercially produced "B. impatiens" is one of the most important species of pollinator bees that are used by greenhouse industry in North America, including Canada and Mexico. They are efficient pollinators and natives to East North America. The interest in "B. impatiens" has been increased even more due to the decline of pollinator.

Bombus impatiens. bee population like "A. mellifera" and the ban on importing "B. terrestris" into North America. They are used as pollinator bees for tomatoes, blueberries, raspberries, and pumpkins.
