Overview

  Epistrophe is a genus of medium-sized hoverflies. There are almost 75 Epistrophe species worldwide, at least 5 species in Minnesota. They occur throughout Europe and North America. They are found in forest edges and openings. Adults feed on flower nectar and pollen. They are species generalists, visiting a variety of flowers. Larvae of European species prey on aphids, and though not known, it is likely that North American species do as well. It is suspected that there is only one generation per year, and that larvae enter a period of diapause.      
           
 
Description
 
 

The face is yellow. The antennae are short, less than three times as long as broad. The plate between the thorax and abdomen (scutellum) is yellow. The lower front plate of the middle thoracic segment (katepisternum) has an upper and a lower patch of hairs. On Epistrophe hoverflies, these are broadly separated in front and narrowly joined in the rear. The abdomen is black with yellow markings. The sides are not parallel and the edges are rolled under. The first segment may have a yellow band or two disconnected spots. The second, third, and fourth segments each have a yellow band.
