Biology: The white to orange or pinkish larvae develop in parenchymal galls on the leaves of Hieracium spp. and Pilosella spp. ( Asteraceae). Each larva develops inside a blotch which is often strongly discolored red to purple. There are often many galls per leaf. Multivoltine; pupation and hibernation in the soil.

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