Pyrgotidae is an unusual family of flies (Diptera), one of only two families of Diptera that lack ocelli. Most species are "picture-winged", as is typical among Tephritoidea, but, unlike other tephritoids they are endoparasitoids; the females pursue scarab beetles in flight, laying an egg on the beetle's back under the elytra where the beetle cannot reach it. The egg hatches and the fly larva enters the body cavity of the beetle, feeding and eventually killing the host before pupating. In the United States, some species of Pyrgota and Sphecomyiella can be quite common in areas where their host beetles (typically the genus Phyllophaga, or "June beetles") are abundant. Like their host beetles, these flies are primarily nocturnal, and are often attracted to artificial lights.
