Robber Fly

Robber Fly (Triorla interrupta)

Triorla interrupta is one of the more common species of robber flies around here. This female has taken down a grasshopper that's too large for her to fly with, but she isn't about to abandon a juicy meal just because some fool with a camera is taking her picture. Grasshoppers seem to be T. interrupta's preferred food when its in open, grassy areas where hoppers abound, but this species is aggressive and will take on just about anything smaller than a bird. Herschel Raney has some shots of T. interrupta feasting on everything from dragonflies to a large horsefly. That's not too shabby for a robber fly that's slightly built and only about 7/8" long.
