Love is in the Air- The conspicuously large Clubbed Mydas Fly (Mydas clavatus) is a harmless mimic of the spider wasps (Pompilidae). They carry their masquerade to the extreme with bold behavior that includes pumping of their abdomen to simulate an ability to sting. Adults visit flowers to feed on pollen and nectar while the larvae are predatory, relying on a diet of scarab beetles (Scarabaeidae) which they find crawling within the dead and rotting wood where they reside. When mating, adults fly around in copula, reminding one of “love bugs” and other members of the fly family Bibionidae, the march flies. This mating pair was photographed along the Susquehanna at Conewago Falls.
