Coleoptera (Beetles)

There are more named species of beetles and beetles make up 25% of all described species. Beetles are fairly easy to recognize and are found in nearly every habitat around the world.

Beetle wings evolved to have the 2 forewings hardened (called the elytra). The elytra provide a protective coating for their soft bodies. Coleoptera is derived from Greek meaning “sheath wings.”

Beetle larvae do not have a single common name like other orders of insects might. Their larvae can be called grubs, rootworms, mealworms, wireworms, or borers. The larvae also have differing feeding strategies, depending on the species. They eat living to dead plant tissue, fungi, carrion, and dung; some may be predaceous and others may be parasitic.

The wood-boring beetles leave their signature with tracks grooved into trees. The shape and size of their burrows are distinctive and indicative of which species has invaded the tree.

It may be argued that to know one kind of beetle is to know them all. But a species is not like a molecule in a cloud of molecules-it is a unique population.
