Hammerschmidtia ferruginea Hammerschmidtia rufa (Fallén, 1817), the black-bristled logsitter, is an uncommon species of syrphid fly observed across 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.

Larvae[1] have been found under bark of aspen, elm, walnut, and willow.
