Gall wasp

Gall wasps, also traditionally called gallflies, or cynipids, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of cynipids are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America. Diplolepididae were traditionally included within the Cynipidae but have since been designated as their own family after some more recent phylogenetic studies.
