Driftless Prairies: Native Habitat Restoration

Nature inspires awe!

Pyrgotidae (Scarab-killing Flies)

These attractive, parasitoid flies are rarely seen because their hosts, scarab beetles, are nocturnal. The ones we do find are those whose hosts are attracted to lights. To date, we believe that adult beetles are the ones being attacked by this family of flies but very little is known about their biology. There are about 350 species described with 9 in the North America. There is a great deal of variety within this family.
