Hemipenthes catulina

(Coquillett, 1894)

Hemipenthes catulina is a of bee fly in the Bombyliidae, first described by Coquillett in 1894. As a member of the Hemipenthes, its larvae are hyper-, developing as parasites of parasitic insects such as ichneumon wasps and tachinid flies that attack caterpillars. The species is part of a diverse family of bee flies, many of which are important agents. Specific details about H. catulina's appearance and precise relationships remain limited in published sources.
