Heringia elongata (Curran 1921),[1] the elongate spikeleg, is an uncommon species of syrphid fly observed in mainly eastern North America but scattered across the US Canadian border to the Pacific Coast.[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 are predators of Eriosoma lanigerum.[3][4]
