Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound.
Brachinus is a genus of ground beetle native to the Nearctic, Palearctic, the Near East and North Africa. Beetles in this genus are commonly referred to as bombardier beetles . The genus contains the following species: [ 1 ] [ 2 ]
To humans, getting "bombed" by a bombardier beetle is a decidedly unpleasant experience. [ citation needed ] This ability has evolved independently twice, as it seems, in the flanged bombardier beetles (Paussinae), which are among the most ancient ground beetles, and in the typical bombardier beetles ( Brachininae ), which are part of a more ...

The False Bombardier Beetle ranges from 14.9 to 20.0 mm long and is bodily and bilaterally symmetric. These beetles are mostly black, with a red/orange color displayed on their thorax and legs. They are known for having a unique defense mechanism, which consists of spraying out fluid from an abdominal gland when threatened. [6]
G. bicolor can be found under bark year-round. [2] The larvae resemble the larvae of actual bombardier beetles to an extent. Not much is known about them. Though they are not bombardier beetles themselves, they can still emit a foul odor (just not as bad as the beetles they mimic). [4]
Brachinus texanus is a species of ground beetle in the genus Brachinus ("bombardier beetles"), in the family Carabidae ("ground beetles"). [1] [2] [3] It is found in North America. Like other bombardier beetles, it can spray a boiling, corrosive liquid from its abdomen if provoked, and as such should not be handled. [2]
