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 known as the short-tailed larvae suited for moist areas such as rot holes of trees.
Brachypalpus oarus, the eastern catkin, is a common species of syrphid fly first officially described by Walker in 1849.

Temnostoma balyras , the Yellow-haired Falsehorn , is a common species of syrphid fly observed in the eastern half of the United States and adjacent areas of Canada. 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 burrow in moist decayed wood using their hooks as rasping organs operated in a forwards and backwards motion by huge muscles housed in the mesothorax and metathorax. The larvae of T.balyras have been described by Heiss in "A classification of the larvae and puparia of the Syrphidae of Illinois exclusive of aquatic forms".
Chalcosyrphus (Xylotomima) piger, 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.
