Biology: The orange larvae develop in leaf galls on Populus spp. ( Salicaceae ). Our records are all from P. tremula . The gall is about 5 mm across, thick walled, and protrudes on both sides of the leaf but mainly on the underside. Univoltine; pupation and hibernation in the soil.

Distribution: Widespread in Europe including Norway, Sweden, Denmark and Finland. Georgia, Kazakhstan and central Siberia.
