title: Rearing Thyridanthrax fenestratus (Diptera, Bombyliidae) on Pemphredon fabricii (Hymenoptera, Crabronidae) prepupae
abstract: Thyridanthrax fenestratus (Fallén, 1814) is a bombyliid with poorly understood biology. It was recently shown to locally but frequently parasitize Pemphredon fabricii (M. Müller, 1911) (Hymenoptera: Crabronidae), a crabronid wasp that abundantly nests in old Lipara -induced galls on the common reed Phragmites australis (Cav.) Trin. ex Steud., 1840. The parasitism modes in Bombyliidae and Thyridanthrax spp. are not uniform. Here, we report that Th. fenestratus switches facultatively between killi
