Biology and notes: The orange larvae develop singly in the swollen flowers of Origanum vulgare ( Lamiaceae ). The gall is lined with black mycelium on the inside. Univoltine; pupation and hibernation in the gall. We mostly obtained pupae and imagines from overwintered galls collected in the spring. One sample consisted of larvae collected from the galls in the autumn.

Distribution: Widespread in Europe and European part of Russia. In Fennoscandia only known from Norway.
