Over the bronze-colored mesonotum run two pale hair ties, which are interrupted halfway along. The scutellum (label) is yellow. The abdomen is mostly mostly black in color. The tergites 2 and 3 have yellow cross bands that can be centrally interrupted. Tergites 3–5 also have pale transverse bands. The seventh tergite of the female has two protuberances. The fourth sternite of the male has a rounded elevation. The legs are mostly light yellow in color.

distribution

The hoverfly species is common in the Palearctic and Oriental . Their occurrence ranges from North Africa and southern Europe through the Middle East , India and Central Asia to the Far East (China). In Germany, it occurs mainly in the warmer climatic regions in the southwest.

Way of life

The hoverflies can be seen from May to September. They prefer poor grassland biotopes as a habitat . The species trains 3–4 generations a year. It hibernates as a pupa in the ground. The first generation adults appear at the end of April / beginning of May . The larvae feed on various tubular aphids , including the soybean aphid ( Aphis glycines ), Melanaphis sacchari , Rhopalosiphum maidis , Rhopalosiphum padi and Lipaphis erysimi . The adult flies feed on nectar and honeydew.
