The Bombardier Beetle is found in :
Asia 2 cms
North America approx 1-2 cms long
South America approx 1-2 cms long
Africa – approx 2-3 cms long
even in Europe, but usually small – approx 1 cm long
They tend to reside in the South of England….
…. and they are found usually under rocks, and close to water
The Bombardier beetle is able to defend itself against a predator, such as an ant or a spider, a bird or a frog which want to eat it for breakfast…. Usually the bombardier beetle wins! It does not kill its attacker but shocks it with a mixture of hot quinone and steam which is enough usually to ward off the spider or ant – no insects or arachnids like quinones and particularly hot chemicals in their face. Birds will not try to take the spitting beetle, and it has been known for bombardier beetles to continue to squirt inside the mouth of a frog, such that the frog then spits it out again.
Much of the initial work experimentally has been done at Cornell University under the leadership of Professor Tom Eisner.
Click on the video to see and hear the typical sound that a bombardier beetle makes when it squirts the blast out of its rear facing tube – though it can bring this to blast in any direction it wishes, even over its head….!
Below is another Bombardier Beetle clip from the film “Alien Empire” which demonstrates the power of the explosive force coming from the beetle…
