Big Bee Flies (Family Bombyliidae)
Bee Flies are big-eyed, with long legs, and long wings that are often strongly-patterned and are held out to the sides like a “V” when at rest. Because they hover, they’re mistaken for Flower-Hover-Syrphid flies. Like Syrphid flies they are bee mimics. Adults are diurnal, feed blamelessly on pollen and nectar from flowers, but most BF larvae are external parasites/parasitoids on the larvae of ground-nesting insects.
