Having, characterized by, or relating to elytra; specifically, belonging to or describing insects that possess hardened front wings.
From Greek 'elytron' (sheath, cover) + '-ous' (having the quality of), used to describe insects with the distinctive hardened wings called elytra.
This is the everyday adjective form scientists use—instead of saying 'has elytra,' entomologists just say 'elytrous insects,' making Coleoptera (beetles) the biggest group of elytrous creatures on Earth!
