Bare-cheeked Bumble Fly

Criorhina nigriventris , the bare-cheeked bumble fly, is an uncommon species of syrphid fly observed across the northern United States, the Appalachian Mountains and southern Canada. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen.
