ROBBER FLY


Meaning of ROBBER FLY in English

or assassin fly

Any of about 4,000 species of predatory dipterans in the family Asilidae, found worldwide.

Robber flies are the largest of all dipterans; some species are 3 in. (8 cm) long. Most have a dull-coloured, stout body resembling that of a bumblebee and a moustache of bristles between the large-faceted eyes. They use their long legs to capture insects in flight and hold them while eating; a fluid injected into the victim breaks down muscle tissue. A few species are serious pests of apiaries.
