Biology and notes: The white larvae develop gregariously in shoots of Hypericum spp. ( Hypericaceae ). The apical leaves of the infected shoots are bundled together and often miscolored red. Probably multivoltine. Pupation and hibernation in the soil. In several cases, we found the larvae living together with yellow larvae of Macrolabis sp. The latter may represent an undescribed species.

Distribution: Western Palearctic. Widespread in Europe including Norway, Sweden and Denmark.
