This fly somewhat resembles a honeybee, and is an example of batesian mimicry. Size is 10 to 13 mm. The eyes are large and dark brown. The thorax is plain brown. There is a thin white band and then a thick black band on the 2nd abdominal segment with an open gold band superimposed on it. The rest of the abdomen is black with thin white cross bands. The 3rd segment is shiny black. The dorsal surface of the thorax is covered with short buff-colored hairs (pile).
Found on flowers from late May to mid-September.
