gall

Globular gall, up to 1.5 cm large, on the lateral of terminal bud of a branch. The gall often basally is narrowed, reminding then of a small fig. The surface has a small number of sturdy warts. The colour of a fresh gall is green with small white specks. Around the gall chamber a hard layer.

hostplants

Fagaceae, monophagous

Quercus frainetto, petraea, pubescens, robur.

notes

Although the gall shown above look quite different, that fall within the variability depicted by Melika. The Hungarian material reminds of A. sternlichti, but in that species the small warts of the gall surface are pointed.

For some time it has been assumed, by amon others Buhr, that Andricus burgundus were the sexual generation of infectorius. This has shown to be incorrect.
