Biology and notes: The white to yellow-orange or pinkish larvae develop in parenchymal galls on the leaves of Sonchus spp. ( Asteraceae ). Our records are all from Sonchus arvensis . Each larva develops inside a blotch which may be strongly discolored red to purple. There are often many galls per leaf. Bi- or multivoltine. Pupation sometimes in the gall, sometimes in the soil. This species is not previously published from Norway, but some records exist in Artskart, the first from Larvik 18. July 2013.

Distribution: Widespread in Europe including Norway, Sweden, Denmark and Finland. Western Asia. Introduced to USA and Australia.
