The primary parasitoids of Zygaena spp. exhibit extreme specialisation to Zygaenidae. However, B. tibialis is a parasitoid of Zygaena, but has a broad lepidopteran host range. The morphology of B. tibialis specimens reared from Zygaena was compared with that of specimens from other host Lepidoptera (Lymantria dispar, Ocnerogyia amanda, Euproctis chrysorrhoea, Archips rosana [A. rosanus], Cacoecia [Archips] sp., Pleuroptya ruralis and 2 tortricid species). Two small differences in the distribution of sensillae on the antennal flagellum and hind tarsi size were consistently detected over a fairly broad geographical range. Several new host records involving Zygaena species are presented, including Z. filipendulae
