    Giant Water Bug - (Lethocerus americanus)

    The mammoth Giant Water Bug looks fierce for good reason. The amphibious insect can bite and pinch prey and anything that threatens it.

    Staff Writer (8/29/2017): This is a large insect species with equally large and very noticeable foreleg pincers. They are used to catch underwater prey like small fish, frogs and sometimes snakes. Its body is mostly flat and oval shaped with dark brown, "dead leaf" coloring. The Giant Water Bug is known to play dead in order to escape predators. It is also able to deliver a painful bite when disturbed or threatened by people (it carries the the nickname of "Toe-biter"). Unsuspecting swimmers may get a toe pinched by one if they step too closely.

    They make their homes at the bottom of muddy waters or surrounding vegetation. They are drawn to light sources at night and, therefore, often find themselves in or around backyard pools. Females may aggressively defend their eggs, which they lay at the edge of waterlines. Their hairy legs help them swim though they can often be found in mud, or hiding at the bottom of ponds.

    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.
