Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis.
Nematinae is a subfamily of sawflies belonging to the family Tenthredinidae. It contains over 1250 described species in ~40 genera. Members of this subfamily feed on a wide range of plants and employ a wide range of feeding habits, both internally and externally, on their host plants.
Trichiosoma is a genus of cimbicid sawflies in the family Cimbicidae. There are more than 30 described species in Trichiosoma.
Arge is a genus of sawflies belonging to the family Argidae subfamily Arginae.
Pamphilius is a genus of leaf-rolling sawflies within the Symphyta belonging to the family Pamphiliidae.
Tenthredo is a genus of sawflies with more than 700 species of the family Tenthredinidae, subfamily Tenthredininae. It is of Holarctic distribution.
Tenthredopsis is a genus of common sawflies belonging to the family Tenthredinidae subfamily Tenthrediniinae. These sawflies are present in most of Europe.
Euura is a genus of sawflies of the family Tenthredinidae, subfamily Nematinae. Some of the larvae feed externally on plants and some form plant galls on willows (Salix species). In the case of the gall-forming species, when the female lays her eggs she injects a stimulant and the gall start to form before the eggs hatch. Most sawfly galls are hard and individual larva tend to inhabit the gall, feeding on the tissue and leave the gall to pupate in the soil. Most of the species are monophages although the type species, Euura mucronata, is polyphagous feeding on over thirty species of willow.
Eriocampa is a genus of common sawflies in the family Tenthredinidae. There are about ten described species in Eriocampa.
