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.
The bombardier beetle is unusual by using a violent exothermic chemical reaction to launch a boiling noxious chemical spray in a rapid burst of pulses from special glands in its abdomen, accompanied with a popping sound. The Anthia (oogpister beetle) will fire formic acid at
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.
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
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.
A photographer’s Covid-era hobby turned into a four-year project that produced around half a million photos. But one stood out from them all.
Investigators trying to determine what caused last week’s deadly midair collision between a US military Black Hawk helicopter and an American Airlines plane near Washington, DC, briefed ...
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 ...
