    Margined Blister Beetle - (Epicauta funebris)

    The Margined Blister Beetle is as black as ebony, but for a thin white line that runs down the middle of the elytra.

    Picture of Margined Blister Beetle
    Staff Writer (8/4/2017): The Margined Blister Beetle can secrete a chemical called cantharidin when threatened. This secretion causes blisters to human skin and can injure an insect predator. This beetle feeds on plant tissue so contact with potential enemies is likely. It may be a garden pest in large numbers and handling individuals may best be avoided.

    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.
