Tropidia albistylum (Macquart, 1847), the Yellow-thighed Thickleg Fly, is a rare species of syrphid fly observed across the eastern and central United States. 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. The larvae are aquatic.^[2]
