Elytra

n. leathery fore wings of beetles and some other insects, meeting in a straight line and serving as protective covers for the hind wings when at rest (Biology)

An elytron (plural: elytra) is a modified, hardened forewing of certain insect orders, notably beetles (Coleoptera) and true bugs (Hemiptera). An elytron is sometimes also referred to as a shard.The elytra primarily serve as protection for the hindwings underneath, which are used for flying. In some groups, the elytra are fused together, rendering the insect flightless. Some of the ground beetles (family Carabidae) are a good example of this.
