Chalcosyrphus anthreas

Chalcosyrphus (Xylotomima) anthreas, the Yellow-banded Leafwalker, is a rare species of syrphid fly found in eastern North America. 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.
