    Robberfly - (Promachus hinei)

    The Robberflies from the genus Promachus are quite loud, but they are very effective hunters.


    Staff Writer (8/24/2017): Robberflies eat all sorts of other flies as well as bees, wasps, beetles and butterflies. If it flies and they can catch it, it becomes dinner. If the Robberfly spies a resting insect and can catch it, it becomes dinner. Robberflies are efficient predators with a big appetite for bugs.

    During the day, they hang from branches or objects near the ground, waiting to ambush passing prey. They chase them in flight, overtake them, and grab them with their legs. Once captured, the robber fly will stop at a branch or leaf and use its stiff mouth to pierce the body of its victim and then suck out the victim's insides.

    Robberflies are fast and loud. It is typical to hear one before actually seeing it. This particular species likes to perch on vertical twigs and branches. Their larvae also eat insects on the ground.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
