	Beetle - Wikipedia, the free encyclopedia
		Beetles are generally characterised by a particularly hard exoskeleton, and the hard wing-cases (elytra) which tend to cover the hind part of the body and protect the second wings, the alae.
		Predaceous diving beetles (family Dytiscidae) may be the most common example, they employ a technique of retaining air when diving between the abdomen and the elytra.
		In these beetles the testes are tubular and the first abdominal sternum (a plate of the exoskeleton) is divided by the hind coxae (the basal joints of the beetle's legs).
