Description

Mating couple

Gymnosoma clavatum can reach a length of 6–8 millimetres (0.24–0.31 in). These flies have a black thorax, but males have a mesonotum with golden pruinosity up to the transverse suture. Scutellum is black with two pairs of marginal setae and a quite characteristic red sub-globular abdomen, without setae but with large black markings in the middle. In the females thorax before the scutellum has three spots of dusting. Abdominal tergites are completely fused. The compound eyes are red. Antennae are black. Wings are slightly darkened, with yellow basicostae. Femora and tibiae are black.[4][5]

Biology

Adults can be found from May to October. These flies are endoparasites of various Pentatomidae species, on which the females lay their eggs. Larvae will develop inside them. Known larval hosts of these parasitic flies are Ancyrosoma leucogrammes, Carpocoris pudicus, Cydnus aterrimus, Dolycoris baccarum, Eurygaster integriceps, Nezara viridula, Palomena prasina, Piezodorus lituratus.[6]
