The four-lined thick-headed fly reaches a body length of 8 to 13 millimeters. The basic color of the forehead, the back of the head and the thorax are black-brown, the abdomen has a black basic color. The latter has yellow hems on the back of the first four segments, the fifth segment is yellow. The label is also black. The antennae are black, the face is colored yellow and has a golden sheen, the keel is brown. The proboscis is brownish at the base, otherwise black. It's about one and a half times as long as the head. The shoulder bumps on the thorax are yellow, the sides of the thorax have shiny welts. The legs are yellow-brown. The female differs from the male in that it has a slimmer, squishy body and its brown theka.
