- Because beetle elytra may be common fossils in Pleistocene deposits, they are often important sources of data on Pleistocene environments.
- However, familiarity with potential prey items greatly enhances recognition of even soft-bodied prey from diagnostic indigestible body parts such as wings, elytra, mandibles, or chelicerae.
Origin
Mid 18th century (denoting a sheath or covering, specifically that of the spinal cord): from Greek elutron 'sheath'.
