    Black Blister Beetle - (Epicauta pennsylvanica)

    Blister Beetles can look ordinary and unassuming, but under duress, they can leave quite a mark on insects and humans alike.

    Picture of Black Blister Beetle
    Staff Writer (1/25/2017): Black Blister Beetles can secrete a chemical that causes irritation, redness and, over time, blister formation on human skin. It is a defense mechanism intended to protect them predators and other threats. This chemical also renders them somewhat distasteful, further aiding in their survival. The Black Blister Beetle is widespread across the continent and can be found on flowering plants, especially goldenrods and asters.
