The principal nervure nearest the interior or posterior margin, with which it includes a space often subtriangular, traversed in most Diptera and many Hymenoptera by another nervure; and in many Tegmina and Hemelytra by several[1046].
The second principal, and often strongest, nervure of the wing[1039].
I counted eleven of these little joints in the upper wing of Andrena cineraria; sometimes, however, instead of a bulla, a nervurestops short to admit the fold.
The other wing consists of a rigid nervure in front and behind of thin parchment which supports fine rods of steel.
At this fold the median nervure stops and is joined by a cross nervure to the radial, which can be distinguished throughout its length from the subcostal.
The hind-wings, when developed, are characteristic in form, possessing a sub-costal nervure with which the reduced radial nervure usually becomes associated.
Close to a transverse fold near the base of the wing, the median nervure divides into branches which extend to the wing-margin; there is a second transverse fold near the tip of the wing, and cross nervures are altogether wanting.
The Gelechiidae are a large family with similar larval habits; the moths are distinguished by the sinuate termen of the hindwing and the connexion of its sub-costal nervure with the discoidal areolet.
The Sesiidae are a large family of small, narrow-winged moths, the sub-costal nervure of the hindwing being absent and the wings being for the most part destitute of scales (fig.
The hindwing carries a frenulum and has its sub-costal nervure connected with the radial by a short bar.
The sub-costal nervure of the hindwing is usually present and distinct from the radial nervure.
The Libytheidae may be recognized by the elongate snout-like palps, the five-branched radial nervure of the forewing, the cylindrical hairy larva, and the pupa attached only by the cremaster.
The maxillae are well developed, the hindwing has a frenulum, and its sub-costal nervure touches the radial near the base.
Noctuidae, but their wing-neuration is more specialized, the sub-costal nervure of the hindwing being confluent with the radial for the basal part of its course.
Note that there are five branches to the radial nervure (No.
The Satyrinae, including our native browns and the Alpine Erebiae, resemble the foregoing group in many respects of structure, but the sub-costal nervure is greatly thickened at the base (fig.
The fifth radial nervure does not arise from the third, the maxillae are well developed, but their palps are obsolete; the head is densely clothed with erect scales; the terminal segment of the labial palp is short and obtuse.
There is a membranous lobe or jugum near the base of the wing, and the neuration of the hindwing is closely like that of the forewing, the radial nervure being five-branched in both.
In this group may be included a number of families of moths with the second median nervure of the forewing arising close to the third.
Teeth of Nervure of Gryllus domesticus (from Landois).
This toothed nervure is rapidly scraped across a projecting, smooth, hard nervure (r) on the upper surface of the opposite wing.
In our British Phasgonura viridissima it appeared to me that the serrated nervure is rubbed against the rounded hind-corner of the opposite wing, the edge of which is thickened, coloured brown, and very sharp.
The bristle (frenulum) arising from the base of the hind wing is held in place by the catch (retinaculum) on the costalnervure of the fore wing.
Tutt, has the fore wings reddish ochreous, the rays whitish, and the shade under the median nervure reddish.
The black shading along the median nervure is sometimes very conspicuous.
In our British Phasgonura viridissima it appeared to me that the serrated nervure is rubbed against the rounded hind corner of the opposite wing, the edge of which is thickened, coloured brown, and very sharp.
This toothednervure is rapidly scraped across a projecting, smooth, hard nervure (r) on the upper surface of the opposite wing.
From another hinder trunk arise the two-branched cubital nervure and three separate anal nervures.
Then comes the radial--usually the most important nervureof the wing--typically with five branches, and the median with four.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nervure" in a variety of sentences. We hope that you will now be able to make sentences using this word.
