Appearance
This species has a black mystax with some scattered yellow hairs, and mostly black hairs surrounding the eyes. The thorax is yellow, and the abdomen has black and yellow stripes. The yellow arc of hairs that extend from the anterior of the thorax to below the wing insert are a useful field mark for identification. The adults are 15–25 mm long.Habitat
Especially spotted along woodland edges.Food
They prey on insects of various species, including other robber flies, bees, wasps and beetles. Their mouthparts are designed to allow them to penetrate the exoskeletons of other insects, after which they inject enzymes into their prey, which liquefy their insides. The robber fly can then suck out the contents of the liquefied insect.References:
