Robber Fly (dysmachus trigonus)
This little fellow, measuring about 15mm long, is just one of many robber flies, so called because they prey on other insects. It is seen between May and August and favour sandy habitats. Worldwide there is an estimated 7,000 of them.
Also called assassin flies, robber flies wait in ambush for other insects, which they usually take on the wing. Once caught they thrust their stout proboscis into them before sucking them dry. The dense moustache of stiff bristles over this one's face is thought to give protection when struggling with its victims.
