Eristalis flavipes, the orange-legged drone fly, is a species of hoverfly native to North America.[1] It flies from early April to mid-October, and occurs in a wide variety of habitats, particularly wetlands. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type.[1]
