Chalcosyrphus (Xylotomima) nigromaculatus (Jones, 1917), the black-spotted leafwalker, is a rare species of syrphid fly observed in Colorado, British Columbia, Oregon [3] and Utah. Hoverflies can remain nearly motionless while 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.[1]
