    Stag Beetle - (Lucanus capreolus)

    Looks can be deceiving. The Stag Beetle drinks sap and uses those intimidating mandibles for courting.


    Picture of Stag Beetle
    Staff Writer (2/6/2014): Common east of the Mississippi, Stag Beetles are noted for their large size and ferocious appearance, complete with a durable exoskeleton and imposing, pincer-like mandibles. The mandibles on the female are much shorter than that of the male, whose mandibles can be about the size of their heads. Among males, younger males have shorter mandibles than older ones. This species is different from other Stag Beetles thanks in part to the orange or yellow coloring at the base of each leg. Its exoskeleton appears very smooth and glossy with a rich dark red or brown hue to it.

    They are primarily night dwellers and - like most nocturnal insects - are generally attracted to light sources at night. Despite having large, "menacing" mandibles, the Stag Beetle serves itself a steady diet of sap. The mandibles on the male are generally reserved for male-to-male combat when it comes time to woo a female Stag Beetle. The winning male gets the opportunity to mate.

    Females lay fertilized eggs on dead trees or stumps. The grubs hatch and mature in the rotting wood.

    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.
