Chalcosyrphus (Xylotomima) piger (Fabricius, 1794), the short-haired leafwalker, is an uncommon species of
syrphid fly found throughout North America and Europe. 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. Larvae have been identified from sappy hollows from Larix and Pinus.[7][8]
