The name of the taxonomic order, Coleoptera, comes from the Greek koleopteros (κολεόπτερος), given to the group by Aristotle for their elytra, hardened shield-like forewings, from koleos, sheath, and pteron, wing. The English name beetle comes from the Old English word bitela, little biter, related to bītan (to bite),[2][3] leading to Middle English betylle.[4] Another Old English name for beetle is ceafor, chafer, used in names such as cockchafer, from the Proto-Germanic *kabraz- (compare German Käfer).[5]
