What is the term for the hardened forewings of beetles?

Explanation:
Beetles protect their wings with a specialized pair of forewings that are hardened into a rigid covering. These are elytra, typically tough and meeting along the midline to shield the hind wings and abdominal segments when not in use. When the insect is ready to fly, the elytra are raised and the hind wings unfold for flight. This feature is a defining characteristic of beetles, setting their wing structure apart from other insects. For comparison, halteres are the small balancing organs found in flies; tegmina are leathery front wings seen in some other insects like cockroaches and grasshoppers; and scales are the colored coverings on the wings of butterflies and moths.
