This is sometimes called the ‘Footballer’ due to its black and yellow striped thorax. The abdomen is distinctively black and yellow patterned, and the yellow face has a dark central stripe. The hind tibia is black in the distal third only. Length 13mm. It maybe confused with other Helophilus species, but mainly Helophilus hybridus.
The larvae are commonly called ‘rat-tailed maggots, and are aquatic, living in rotting vegetation in muddy conditions at the sides of ditches and ponds, even in puddles. The adults feed on nectar.
It flies April to October. Found almost anywhere, including gardens. Common and widespread.
