Arthropod Structure and Development, 2015
This paper provides the first comparative anatomical study of the explosive pygidial defensive system of bombardier beetles in species classified in three brachinine subtribes: Brachinus (Brachinina), Pheropsophus (Pheropsophina) and Aptinus (Aptinina).

Defense of bombardier beetles against avian predators
The Science of Nature, 2020Bombardier beetles (Coleoptera, Carabidae, Brachininae) possess a remarkable defense mechanism where a hot chemical spray is released from the tip of their abdomen, with an audible explosive sound. To date, the repellent properties of these chemicals have been tested against a limited number of taxa, such as amphibians and insects.

Morpho-functional and behavioral studies on the flanged bombardier beetles (Carabidae: Paussinae)
, 2013 Paussinae, known as flanged bombardier beetles, are a monophyletic subfamily that includes about 750 described species mainly distributed in tropical regions. They share a unique type of larva with a peculiar terminal disk at the end of an up-curved abdomen, and an explosive defensive strategy that parallels that of brachinines.

Nonlinear Dynamics of the Bombardier Beetle
Volume 7B: 17th Biennial Conference on Mechanical Vibration and Noise, 1999Abstract This work investigates the dynamics by which the bombardier beetle releases a pulsed jet of fluid as a defense mechanism. A mathematical model is proposed which takes the form of a pair of piece wise continuous differential equations with dependent variables as fluid pressure and quantity of reactant.

Spray Mechanism of the Most Primitive Bombardier Beetle (Metrius Contractus)
Journal of Experimental Biology, 2000ABSTRACT The bombardier beetle Metrius contractus discharges its defensive secretion as a froth that clings to its body. When attacked from the rear, it allows the froth to build up over the gland openings near the abdominal tip; when attacked from the front, it conveys the secretion forwards along special elytral tracks.

Chemoecology, 2001
Metrius contractus, a primitive paussoid bombardier beetle, emits its defensive quinonoid froth with accompanying sound (a faint “hiss”), but the sound is not pulsed, indicating that the secretory emission itself is not pulsed. Pulsed secretory delivery in bombardier beetles appears to occur in Brachinini only.
