on Quercus, agamous generation

Andricus pseudinflator: gall on Quercus lusitanica

Quercus lusitanica, gall (from Houard, 1908a)


smooth, green, 3-4mm large, ± rotund bud galls of lateral or terminal buds, initially enclosed by the bud scales for half of their height.

host plants

Fagaceae, monophagous

Quercus faginea, lusitanica, pubescens, robur.

on Quercus, sexual generation


the length growth of a young shoot has been stopped, and its tip is swollen clublike. Inside a spacious cavity, lined with a spongy tissue, which houses a small inner gall.

host plants

Fagaceae, monophagous

Quercus faginea, lusitanica, pubescens, pyrenaica, robur.


Andricus bocagei Kieffer, 1901.


As the species name already suggests, the galls of both generations strongly resemble those of A. inflator. The gall of the sexual phase is much smaller (4-6 mm, as opposed to 8-15 mm in inflator).


Synergus ruficornis.

parasitoids, predators

Ormyrus pomaceus.
