The site covers all Europe, i.e. including European Russia and the Ukraine, the Mediterranean Islands, the Greek Islands and Cyprus. North Africa, the Levant, and Turkey are not within its scope, and are treated only marginally.
which insect species?
All plant parasites whose activities induce a more or less specific, externally recognisable, reaction, or characteristic damage pattern; and also related species, which may be expected to cause similar reactions or damage, even occasionally, like under high densities. Apart from a few conspicuous mushroom galls, the scope of the site are parasites of seed plants, Spermatophyta.
which plant species?
All plant genera on which mines have been observed within the geographical scope are included as much as possible. Ornamental and crop plants are not excluded. However plants growing in greenhouses and their parasites are not dealt with.
The nomenclature of animals follows the Fauna Europaea and its successor (PESI), “the Pan-European Species directories Infrastructure”. The naming of fungi as far as possible follows the Index Fungorum. For plants the source is the Euro+Med PlantBase; however, this is not yet completely finished; when necessary the Plant List is used.
Synonyms are mentioned only is far as they play a role in the cited references .
