Andricus cydoniae: gall on Quercus cerris

Quercus cerris, gall (from Houard, 1908a)

gall

Downy hairy, green (ultimately brown and woody), more or less ovoid gall of about 1.5 cm long at the end of a branch. From the gall often some more or less normal leaves may sprout. Near the tip the gall has a large hole that opens into a spacious gall chamber that has a large number of ovoid inner gall in its lower half, each with one solitary larva that pupates within the gall.

hostplants

Fagaceae, monophagous

Quercus cerris, petraea, robur, suber.

notes

This probably is the sexual generation of either Andricus hartigi or A. truncicola (Stone ao, 2008a).
