Common in many parts of Maryland, especially in the fall. In Maryland, it flies primarily from April to May and September to early November. The summer gap in observations suggests the possibility that this is at least in part a migratory species in the state. Some nearctic flower flies (family Syrphidae) have been found to be migratory, but flower fly migration in North America has been little studied overall. In the fall it can be found on a variety of flowering plants in meadows and fields near the coast, but it is otherwise associated with forests.
By far the most common large flower fly in Maryland with the general pattern of a wide, dark abdomen punctuated by several thin white transverse lines. The small black triangular area at the base of the wings distinguishes it from all other members of the genus except E. saxorum, which shows a variable amount of metallic blue, visible from certain angles, on the abdomen and/or scutum.
