Criorhina Bumble Bee Mimics

The syrphid genus Criorhina includes many large remarkable bumble bee mimics. At a distance, even a veteran insect watcher may be fooled. Viewing with butterfly binoculars or close up photos reveals the distinctive fly antennae and, possibly, only one pair of wings.

Photos 2, 3 and 4, especially, show the long face the genus was named for.

I have photographed four Criorhina species on the Olympic Peninsula:

C. tricolor — 1, 2
C. bubulcus
— 3, 4
C. kincaidi — 5, side view, mating pair
C. nigripes — 6
