Dioctria infuscata Meigen, 1820 Dioctria bicincta is a species of robber fly classified in the subfamily Dasypogoninae of the family Asilidae.

This species can be found in most of Europe (Austria, Belgium, Croatia, France, Germany, Greece, Italy, Poland, Spain, Switzerland, Netherlands and former Yugoslavia).

[3][4] Dioctria bicincta can reach a body length of about 7–9 mm (0.28–0.35 in).

Also the abdomen is usually black, sometimes with partly reddish marks on the middle tergites.

This species is rather similar to Dioctria linearis (drawing of the abdomen and color of the legs are almost identical)[5] and to Dioctria gracilis (females of these two species cannot be easily separated).
