The elytra of this cockchafer beetle are readily distinguished from the transparent hindwings.. An elytron (/ ˈ ɛ l ɪ t r ɒ n /; from Ancient Greek ἔλυτρον (élutron) 'sheath, cover'; pl.: elytra, / ˈ ɛ l ɪ t r ə /) [1] [2] is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs such as the family Schizopteridae are extremely similar; in true ...
The elytra are connected to the pterathorax; being called as such because it is where the wings are connected (pteron meaning "wing" in Greek). The elytra are not used for flight, but tend to cover the hind part of the body and protect the second pair of wings (alae). The elytra must be raised in order to move the hind flight wings.

In annelids, elytra (/-t r ə /; from Greek ἔλυτρον "sheath, cover"; sg.: elytron / ˈ ɛ l ə t r ɒ n /) [1] are shield-like scales that are attached dorsally, one pair on each of a number of alternating segments and entirely or partly cover the dorsum.

The rove beetles are a family (Staphylinidae) of beetles, [2] primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of ...
Many have the two elytra fused together, forming a solid shield over the abdomen. In a few families, both the ability to fly and the elytra have been lost, as in the glow-worms (Phengodidae), where the females resemble larvae throughout their lives. [76] The presence of elytra and wings does not always indicate that the beetle will fly.
The thistle tortoise beetle can be recognized by its green, rounded back and it can be found on thistle plants in many regions of North America and Europe. The thistle tortioise beetle was first discovered in 1902 in Lévis, Quebec. In 1931, Nellie F. Paterson was the first to document the mature larva.
Earwigs make up the insect order Dermaptera.With about 2,000 species [1] in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings".
The species Mormolyce phyllodes is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their fore leg tibiae bearing a comb of hairs used for cleaning their antennae .
