A single beetle or any member of the insect order Coleoptera.
From Greek 'koleos' (sheath) + 'pteron' (wing), literally meaning 'sheath-winged.' The term describes the beetle's characteristic feature of hardened front wings (elytra) that cover and protect the membranous rear wings used for flying.
The word 'coleopteron' appears in scientific naming but is rarely used in everyday speech—scientists just say 'beetle.' However, the Latin plural 'coleoptera' (the order name) is used constantly in scientific literature.
