Elytron - Wikipedia
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 bugs, the forewings are called hemelytra ...
Elytra | insect anatomy | Britannica
The short, thick elytra protect the second, fully developed pair of flying wings. These functional wings can be unfolded rapidly from under the elytra when the beetle is ready for flight. They must be refolded carefully after use, however, often with the aid of both the abdomen and…
Elytra - Amateur Entomologists' Society (AES)
Elytra (singular elytron) are the tough fore wings of beetles and earwigs. The elytra are not used in flight but are used to protect the more delicate hind wings. The elytra are often coloured or decorated with pits and grooves.
Elytron - an overview | ScienceDirect Topics
Adult beetles are distinguished from all other insects by the presence of hardened fore wings called elytra (singular elytron) that cover and protect the membranous hind wings (Fig. 6.1). Coleoptera means “sheath-winged” in Greek. The size range of beetles is impressive, varying from 0.25 to 150 mm; however, most species are 2–20 mm long.

Formation of Rigid, Non-Flight Forewings (Elytra) of a Beetle
2012年4月26日 · Primitive insects have two pairs of membranous flight wings, but during the evolution of the beetle lineage the forewings lost their flight function and became modified as hard, rigid covers called elytra for protection of soft body parts of the abdomen and also the delicate flexible hindwings, which retained their flight function.
elytron, elytra, elytral, elytrum - BugGuide.Net
2011年5月12日 · elytron noun, plural elytra, adjective elytral - the wing cases; especially the hardened sheath-like fore-wings of Coleoptera (Beetles). Another singular form, less frequently used, is elytrum. In groups such as true bugs, where it is incomplete, it is called a hemelytron (plural hemelytra).
ture from those of any other order of insects, but the two pairs of wings are modified in different ways. The fore wings, or elytra, have lost their flight-function, and have become thick- ened protective organs; while the hind wings are, in most cases, transversely folded, which has resulted in a great modification
Elytra reduction may affect the evolution of beetle hind wings
In this paper, we focused on rare group of brachelytrous beetles with exposed hind wings. We have investigated whether the elytra loss in different beetle taxa is accompanied with the hind wing shape modification, and whether these changes are similar among unrelated beetle taxa.
hind wings are reduced to mere nubs used for balance and direction during flight. HALTERE Elytra (sing. elytron) are the hardened, heavily sclerotized forewings of beetles (Order Coleoptera) and are modified to protect the hind wings when at rest. A variation of the elytra is the hemelytra. The forewings of Hemipterans are said to be
