Biology: The yellow to orange larvae are

inquilines in the leaf galls of the wasps Neuroterus albipes (Schenck, 1863) and N. quercusbaccarum (Linnaeus, 1758) ( Hymenoptera : Cynipidae ) on Quercus petraea and Q. robur ( Fagaceae ). Our records are from galls of N. quercusbaccarum on Quercus sp. The larvae live in the narrow space between the disc-shaped gall of the host and the lower surface of the leaf. Univoltine; pupation and hibernation in the soil.

Distribution: Widespread in Europe including Norway, Sweden and Denmark.
