Trichopsomyia apisaon,[1] the black-haired psyllid-killer, is a common species of syrphid fly observed all across North America.

[2] 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 when known are psyllid, aphid and Phylloxera predators.
