Coleoptera – Beetles

There are more named species of beetles than any other group and beetles make up 25% of all the species that have been described. Beetles are some of the easier recognized, probably because of their hardened elytra.  Instead of having 4 wings, they have evolved to have the 2 forewings hardened (called the elytra), providing a protective coating for their soft bodies. Coleoptera is derived from Greek meaning “sheath wings.” Beetles are found just about everywhere in the world and in every habitat.

Beetle larvae do not have a single common name like other orders of insects might. Their larvae can be called grubs, rootworm, mealworm, wireworm, or borers. The larvae feeding habits range from living to dead plant tissue, fungi, carrion, and dung; some may be predaceous and other may be parasitic.

The wood-boring beetles leave their signature on trees by their tracks. The shape and size of their burrows as they drill to the center of the tree is distinctive and indicative of which species has invaded the tree.

I have done my best to ID these accurately and have lots of good help from the folks at BugGuide, which is an indispensable resource for all things insects! Here’s a list of references I used for the information provided and the IDs. Of course, if you find any errors, please let me know.

I’ve listed all the beetles alphabetically by family and alphabetically within the family – for ease of use. If you click on the family name, you’ll be taken to a page with info on that family and a gallery of photos of beetles within that family. Each photo is linked to an individual page if you want to look at other photos of the same insect and learn more about that particular genus. All photos are taken by me.
