Andricus serotinus: galls on Quercus robur

Quercus robur (from Houard, 1908a).

gall

Bud gal, derived from a dormant bud of shoot more than one or two years old or at the base of a stem, largely covered by leaf litter or soil. The gall itself, a white or red globule of some 5 mm, is completely hidden by a large number of thread-like filaments that are up to a cm long, gradually becoming thinner towards their tip, and erect, white-hairy. The gall is unilocular, thin-walled; the solitary larva pupates in the gall. Often several galls are united into a globular mass.

hostplants
