Andricus inflator Hartig, 1840on Quercus, asexual generation
Quercus robur, Rheden, Stikke Trui
The unilocular gall contained three larvae.
The wall consists of an extremely hard inner layer, and a soft outer layer that in the course of time disintegrates and disappears. After removal of the outer layer the inner layer appears to have a ribbed surface.
