beetle,

Beetles have chewing mouthparts and well-developed antennae. They are characterized by a front pair of hard, opaque, waterproof wings called elytra, which usually meet in a straight line down the middle of the back. The elytra cover the rear pair of membranous flight wings, protecting them and the body from mechanical damage and desiccation. Beetles are poor flyers compared with many other insects, but they are well adapted for surviving rigorous conditions. They are found everywhere except in oceans and near the poles, and they occupy nearly every kind of habitat. Most are terrestrial, but some are underground tunnelers and some live in water.

(15 cm) long; tropical species are the largest. Most are dull, but members of several beetle families are brilliantly colored, some with a metallic or iridescent sheen. The majority of beetles are plant eaters, but there are also many predators and scavengers and a few parasites.
