Biology and notes: The larvae develop in stems of Phragmites australis ( Poaceae), often in the galls of Lipara spp. ( Diptera: Chloropidae), but we have also found it associated with mite galls. Univoltine; pupation and hibernation in the host plant. We have not collected larvae of this species, but we have hatched adults from galled Phragmites straws collected in late autumn or early spring. The species is part of a complex of gall midges which utilize Phragmites australis . The species is reviewed in Skuhravá & Skuhravý (1981).

Distribution: Widespread in Europe including Norway and Sweden. Central Asia.
