The abdomen is covered with dense honey-colored and red hair. The color of the abdomen in various individuals varies from black pilose to orange or red pilose. The eyes are large and dark brown. The legs are black and fuzzy and the tarsii on the hind legs are orange. The orange tarsii is a distinguishing characteristic of this species. This fly was identified by volunteer experts at the BugGuide website.
This fly is believed to be uncommon in Fontenelle Forest and Neale Woods during late spring and summer.
This fly mimics large bumble bees in looks and behavior. It also makes a loud buzzing sound while flying. The larvae of the genus are known as “rat-tailed maggots” for the long breathing tube they can extend to the surface of the water. The larvae live in polluted water or wet carcasses.
