Robber flies have voracious appetites and feed on a vast array of other arthropods, catch their prey in mid air.

Robber flies exhibit minimal courtship behavior. The male pounces on the female much like an act of prey acquisition. Copulation is accomplished in a tail-to-tail fashion with the male and female genetalia interlocked. Flight is not completely inhibited during mating.

It always keep its territory and watch the area from a point.
