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 ...
Microscope image of an individual elytron from Augenerilepidonotus dictyolepis.Note the fringing papillae on the border. 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.

Elytra are a synapomorphy for placing any living species into the beetle clade, Elytra are plesiomorphic between clades of beetles, e.g. they do not distinguish the dung beetles from the horned beetles. The metapleural gland is a synapomorphy for placing any living species into the ant clade.
There are no ridges on the top of the head, and the beetles do not have a stridulatory file, a part used to make sound. The eyes are large and protuberant, with finely facetted ommatidia, and the antennae are 11-segmented and reach past the middle of the prothorax but not the middle of the elytra. They are shaped like thread and may have single ...
Water loss is also the reason that the elytra are fused in Eleodes. [9] As expected, species found in forests, such as members of the subgenus Blapylis are smaller, closer to the size of most other insects. Eleodes are generally more active at night, some species are strictly nocturnal while others can and will be active during the day. As ...
This species possess a large and membranous secondary pair of wings actually used for flying. When not in use, they are kept completely folded beneath the elytra. The head is whitish, with a black Y-shaped horn in males, used as a pry bar in battles with other males over feeding sites or mates. These beetles feed primarily on tree sap and fruits.
The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...
Firefly is developing Elytra, a lineup of orbital transfer vehicles designed to move payloads and satellites from one orbit to another within LEO, GEO, and cislunar space. Elytra would allow smaller rockets (such as Firefly's own Alpha) to deliver larger payloads to more difficult orbits, and enable satellite relocation, servicing, mission ...
