    Dentate Stink Beetle - (Eleodes dentipes)

    Stink Beetles are at home in the Sonoran desert of the American Southwest and northern Mexico.

    Staff Writer (6/25/2015): Most Darkling Beetles like this one are completely black. Their heads are round and wide and their antennae somewhat resemble a row of black pearls. There are a variety of species in the Eleodes genus, many of them found in Mexico. They are members of the Stink Beetle, or Pinacate Beetle Family, meaning they are capable of spraying pungent, malodorous chemicals from the tip of the abdomen in defense. To prepare for discharge, they lift the abdomen into the air, almost as if doing a headstand. Some predators have found ways to avoid getting sprayed. Mice pick up the Stink Beetle and force its 'tail' into the ground before eating it from the head down.

    Adults are wingless and cannot fly. The elytra (wing covering) is fused at the midline to prevent desiccation. This species is lives and thrives in a desert habitat, so water preservation is worth the sacrifice. This insect is a scavenger of plant debris and can be found walking the ground looking for bits of plant matter to eat. Its larvae are also called false wireworms and can be found just below the surface nibbling on decaying plant matter. Adults are active from spring through autumn. During the day, they can be found hiding under rocks, wood or in abandoned rodent holes. At dusk, they start scrounging the area for food.

    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.
