The elytra of this
cockchafer are readily distinguished from the transparent hindwings.
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.
