Biology: The white larvae develop gregariously in galled flower buds of Ranunculus spp. ( Ranunculaceae ). Our records are all from R. acris . Infected buds become slightly misshapen, develop brownish rot on the inside, and do not open. Apparently univoltine. Pupation and hibernation in the soil.

Distribution: Widespread in Europe including Norway, Sweden and Denmark. North-west Russia.
