larva

gall

group of about 30, 5 mm long galls that erupt at all sides from a not too thin branch. Each individual gall is unilocular, sticky, and egg-shaped. Fresh galls are attended by ants.

hostplants

Fagaceae, narrowly monophagous

Quercus cerris.

notes

Only the agamous generation is known. Several older authors supposed that Dryocosmus nervosus is the sexual generation, and Hellrigl states this for certain, but the Fauna Europaea (2013) takes both as independent species.
