    Rhinoceros Beetle - (Xyloryctes jamaicensis)

    The conspicuous and harmless Rhinoceros Beetle male is a large and easily recognizable beetle that doesn't let its fame go to its head.

    Picture of Rhinoceros Beetle
    Staff Writer (1/26/2017): The Rhinoceros beetle is best identified by the presence of a horn protruding form its head. This horn is used to keep other males away from a female. Rhinoceros Beetles are not known to bite and are considered somewhat friendly. Adults may eat dead roots and larvae are believed to feed on dead and decaying plant matter on the forest floor.

    Rhinoceros Beetles are found in woodlands west of the Rocky Mountains. Ash tree roots are a noted food source for larvae. Adults are mostly active at night and may be attracted to lights.

    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.
