    Great Black Wasp - (Sphex pensylvanicus)

    The iridescent Great Black Wasp pollinates flowers while feeding itself, and removes plant pests while feeding its young making it a great friend to gardens and fields.


    Picture of Great Black Wasp
    Staff Writer (6/14/2017): Steely blue-black and large, the Great Black Wasp is a nectar and pollen eater. It can be seen visiting flowers in the hottest parts of the summer and early fall and help pollinate plants. Every adult, however, was raised on a diet of Katydids, Grasshoppers or Crickets. (Katydids are relatives of grasshoppers and crickets.)

    Great Black Wasps are part of the Digger Wasp family, creating burrows in the soil. Adult female wasps hunt for insects after laying fertilized eggs in this underground nest. Each egg laid in a tunnel and a Katydid or Cricket is placed next to it. Once the egg hatches, the emerging larva has an immediate food source and will devour the insect as it grows and develops. Their juvenile diet helps keep the katydid, cricket and grasshopper populations under control.

    Adult Great Black Wasps may look mean, but they are disinterested in humans and are not bothersome, though they can sting if mishandled or threatened.

    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.
