Biology and notes: The pinkish larvae develop gregariously in flowers of Vicia cracca ( Fabaceae ). They do not appear to cause visible galling. In some cases, we have found the species together with Contarinia craccae , but it is not clear whether they occupied the same or different flowers. Some of the larvae proceeded to hatch without diapause, while others hatched after hibernation, indicating that the species is bi- or multivoltine. Pupation and hibernation take place in the soil.

Distribution: Known only from Kazakhstan and Norway.
