Brachinus hirsutus is a of bombardier beetle in the Carabidae, characterized by its ability to produce defensive chemical sprays. It is found in Central America and North America, with records from Mexico and the United States. Like other members of the Brachinus, it possesses specialized defensive glands that can discharge hot, noxious chemicals when threatened.
