This document summarizes key characteristics of the order Coleoptera (beetles). It describes their defining physical traits of having wing covers called elytra. It outlines the three main suborders - Adephaga, Archostemata, and Polyphaga - and differences in their hind coxa attachment and wing vein presence. Finally, it briefly profiles several common beetle families, noting defining features like bioluminescence in fireflies or furry bodies in khapra beetles.
