Common Red-legged Robberfly - Dioctria rufipes

Alternative names
Common Red-legged Robberfly
Description

Size approx 15 mm. The front 2 pairs of legs are usually completely orange-red and the hind legs almost wholly black, though variants do occur (see image below). All Dioctria species have shiny patches on the side of thorax which in good light show as silvery patches or 'shimmer stripes'.

D. rufipes has a particularly well-developed tubercle at the base of the antennae which helps to distinguish it from other Dioctria species.
