Beetles are the sole member of the order Coleoptera which means sheath-wing. What distinguishes beetles from other orders of insects is that their front pair of wings are hardened into wing-cases (elytra). These wings act like armor to protect the beetle's rear wings and abdomen. The hardened elytra is very difficult for a predator to penetrate.
With approximately 370,000 species, beetles also comprise more species of insects than any other insect. In fact, there are more species of beetles identified than any other animal species!
