Beetles might be the most successful creatures on earth! Their incredible ability to adapt to any environment makes sure that they will exist, probably long after humans have disappeared from earth. One of the most important features of the beetles that makes them distinctly beetles is their elytra, the hard exoskeletal covering over their wings. Elytra have many functions, but the most important is protection for the beetle.
Some species are able to trap moisture on their wings and keep it because the elytra protects it from the heat and wind.
Insects in the order Coleoptera are commonly called beetles. Coleoptera is the largest order in the entire animal kingdom. There are more species of beetles than species of plants!
