The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
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 ]
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]
The following is a list of beetles of subfamily Paussinae of the family Carabidae of Nepal. Sixteen different species are listed. Sixteen different species are listed. This list is primarily based on Peter Nagel's 2018 "Flanged Bombardier Beetles of Nepal (Insecta: Coleoptera: Carabidae: Paussinae), with nomenclatural and taxonomic notes and ...
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 species fly from May to June. The lifecycle is not known but the larvae are thought to be external parasites that feed on the pupae of other beetle species including Amara convexiuscula and a staphylinid beetle, Tasgius ater (Gravenhorst, 1802). [3] When disturbed, the species shoot liquid from two glands through their anus.
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]
