So complex and exact is the defence mechanism of the bombardier, involving secretion of hydroquinones and hydrogen peroxide in a 'reaction chamber' inside the very bowels of the beetle, that many creationists have championed the bug as evidence that [[Theory of evolution|evolutionary theory]] is a fallacy.<ref>Bomby the Bombardier Beetle, by Hazel Rue, ISBN 0-932766-13-7</ref><ref>Armitage, Mark H. and Mullisen, Luke, [http://www.creationontheweb.com/content/view/1591/ Preliminary observations of the pygidial gland of the Bombardier Beetle, Brachinus sp.] Journal of Creation 17(1):95–102, April 2003</ref>

Experimental evidence shows that hydrogen peroxide and hydroquinone do not explode spontaneously, as creationist writers have sometimes claimed, if mixed without a chemical inhibitor.<ref>Dawkins, Richard, 1987.

If the liquid exploded outside the beetle, it would be a less effective defence because the beetle would not be able to direct its force against its attacker.<ref>Aneshansley, Daniel J. & T.
