two larvae

Occupied galls can be recognised in autumn by their brown and mottled appearance

Seen from below the gall has become concave.


inquiline of the gall wasp Neuroterus quercusbaccarum, less often N. albipes.

host plants

Fagaceae, monophagous

Quercus petraea, robur.


Diplosis, Clinodiplosis, galliperda.


The galls of Neuroterus albipennis and N. quercusbaccarum are both parasitised by the larvae of Parallediplosis galliperda and Xenodiplosis laeviusculi. The difference between the two parasites can be seen at the anal segment of the larvae.
