Material: AAY, Tvedestrand: Risøya, 58.653734°N 9.150944°E ± 4m, 19 June 2021, L2M leg. HE, coll. NHMO .

Biology and notes: The pinkish yellow larvae live in galled flowers on Frangula alnus ( Rhamnaceae). The species is assumed to be an obligate inquiline of Contarinia rhamni . Probably univoltine. Pupation and hibernation in the soil. We found the species together with the host in galled flowers of Frangula alnus collected in Tvedestrand, and successfully hatched males of both species. The males of Dasineura frangulae were bright orange, which is unusual for Dasineura but typical for Macrolabis . The male gonocoxites were small, however, ruling out Macrolabis, and the general build and chaetotaxy confirm the placement in Dasineura (Figure 18 D).
