Hemipenthes jaennickeana
Hemipenthes jaennickeana is a species of bee fly in the family Bombyliidae, characterized by its hyper-parasitic larval lifestyle. Like other members of the genus Hemipenthes, its larvae develop as parasites of other parasitic insects, specifically targeting ichneumon wasp and tachinid fly larvae that themselves parasitize caterpillars. The species was described by Osten Sacken in 1886 and is part of a diverse family of true flies that often mimic bees in appearance.
