Biology and notes: The white to pink or orange larvae develop gregariously in galled flower buds of Chelidonium majus ( Papaveraceae). Infected buds are disfigured and do not open. The larval color is described as pink in the original description, but our larvae tended more towards orange. We collected larvae both in June and August. Larvae collected in June proceeded to hatch the same year without diapause. From this we infer that the species is at least bivoltine. Pupation takes place in the soil, and hibernation probably also takes place there.

Distribution: Known from Germany, Norway, Sweden, Denmark and Russia (Middle Volga region). Probably also from Serbia (Simova-Tošić et al. 2000).
