    American Oil Beetle - (Meloe americanus)

    With a slick black body and smooth shape, the seemingly simple and ordinary American Oil Beetle looks deceptively harmless.

    Staff Writer (8/11/2017): American Oil Beetles are a type of Blister beetle. When threatened or put under pressure, they emit a chemical called cantharidin that creates blisters and irritates human skin.

    American Oil Beetles have a soft, yet stout abdomen with a shell covering that looks like a series of overlapping plates. The surface is slightly bumpy, not slick and smooth. Antennae are visible on the head. The insect can appear as a dull black or in some cases a shiny black or dark blue.

    These particular beetles do not fly and are slow movers. The larvae are devious. They sit on flowers, waiting for a bee to land. They latch onto the bee for a free ride back to the hive. Once there, the beetle larvae then feed on the bee larvae. Adults can be found walking around plants they eat, such as buttercups. They are active all year, but more so in the spring, when they are more likely to be seen.
