Criorhina nigriventris (Walton, 1911), 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. The
larvae of this
genus are found in decaying wood.[6][7]
