Trichopsomyia recedens explained

Trichopsomyia recedens, the shadowy psyllid-killer, is a species of syrphid fly observed in widespread locations in 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 when known are psyllid, aphid and Phylloxera predators.^{[1] [2] [3]}
