Biology and notes: The pink to orange larvae develop in the capitula of Pentanema salicinum ( Asteraceae). Infected flowers do not show outward signs of damage. Pupation and hibernation take place in the soil. We collected larvae in July. Some of these proceeded to hatch without diapause, whereas the majority hatched after hibernation. This indicates that the species is at least partly bi- or multivoltine. From the same flowers, we hatched at least three other species of gall midge. These await further examination, but one species belonged to Clinodiplosis, whereas the remaining species may be predators and/or fungivores.

Distribution: Only known from Norway, Sweden, Denmark and Kazakhstan.
