Insect Order (Coleoptera)
COLEOPTERA
Beetles is the largest order of the animal kingdom and a common site throughout the state of Tennessee, particularly in the summer months. Around 25,000 species are recognized in North America alone. They are resilient creatures, able to make a home in most any environment, from deserts to forests. They are identified by their hardened bodies either with a dull or shiny finish. They are an essential part of the natural ecosystem in that species feed on other insects, animal remains, and plants. Bodies of beetles typically showcase three separate sections - the head, pronotum, and abdomen. Over the abdomen rests wings which are covered over by the elytron, a hardened shroud. Notable beetle types include Lady Beetles (Lady Bugs), the imposing Stag Beetles, and the common black Ground Beetle.
