Andricud pictus: gall on Quercus pyrenaica

Quercus pyrenaica, gall (from Houard, 1908a)

gall

Galling of the cupula; the acorn is more or less reduced. The basal shape of the gall is a low cone, its base provided with a number of long, slender processes. Fresh galls are deep red and very sticky (and resemble especially then strongly the galls of A. dentimitratus); later they turn brown and dry. Occasionally the gall occupies a bud.
