Fagus sylvatica, Bussum; the same, very early stage; the gall at left is the most advanced of the three. When from that gall the upper epidermis is taken away, it appears that a tuft of white hairs has developed below it (photo at right).

gall

Larva white, solitary; a single generation per year; the larva hibernates in the fallen gall and pupates therein also in spring.

hostplants

Fagaceae, monophagous

Fagus orientalis, sylvatica.

synonyms

Oligotrophus fagineus Kieffer, 1909; Phegobia tornatella (bremi 1847).

notes

the ontogeny of the very first stages of the gall is described by Rohfritsch (2011a).

Galls mainly high up in the canopy (Kampichler & Teschner, 2002a).

The larvae may be killed within their gall by a strong development of the endophytic fungus Apiognomonia errabunda.
