Yellow-legged Wood Fly

Blera humeralis, the yellow-legged wood fly, is an uncommon species of syrphid fly officially described by Samuel Wendell Williston in 1882. Hoverflies are so-named for the ability to remain nearly motionless while in flight. The adults are known as flower flies, as they are commonly found around and on flowers from which they get energy-giving nectar and protein-rich pollen.
