Galerita bicolor
False bombardier beetle
Galerita bicolor, commonly known as the false bombardier beetle, is a ground beetle species occurring in the eastern United States. It exhibits Batesian mimicry of true bombardier beetles (Brachinini), sharing their characteristic red-and-black coloration without possessing the explosive defensive chemical spray. Adults are large, elongated beetles measuring 17.0–22.5 mm, found primarily in moist woodland and meadow habitats. The species is active year-round under bark and leaf litter, with peak activity from February through November.
