Greece, Lesbos, Andissa, 30.iii.2019; the galls were > 35 and extremely hard
detail, with exuvium
gall
globular, monolocular gall, derived from a terminal or lateral bud, with a diameter of 10-15 mm. The surface is sparsely covered by a number of 2-3 mm high pointed warts, connected by ridges. Young galls are green and fleshy, thy ripe gall is pale brown, extremely hard and does not fall off.
host plants
Fagaceae, monophagous
Quercus infectoria & subsp. veneris, pubescens, robur subsp. pedunculiflora.
notes
The galls from Lesbos were considerably larger than the description, and darker in colour.
Only the asexual generation of this species is known. If a sexual does exist, it probably lives on Q. cerris.
The gall can easily be confused with the one of A. infectorius.
