Usually segments 7 to 9 and 13, each have a pair of fleshy pads, which are termed prolegs and are furnished on their edges with a row of minute hooklets (see Plate I.
These larvae often coil themselves up when at rest, clinging firmly with their large prolegs to their food-plant.
The larva is moderately stout, and the two prolegs are very close together.
Larva elongate, slender, with few hairs, without prolegs on segments 7 to 9; often imitating live or dead twigs and shoots.
There is a series of fleshy filaments of a pinkish-brown colour along each side of the insect, and an extra pair of prolegs on the ninth segment.
It is these hooklets which enable caterpillars to hold on by means of their prolegs with such great tenacity.
The legs are very minute, and the prolegs of moderate size.
Its head is small, and pale Indian yellow in colour; its anal and ventral prolegs are large; on being touched the caterpillar coils itself up very rapidly and closely.
Larva usually without prolegs on segments 7 and 8, segment 12 more or less prominent above.
Larva more or less elongate, usually with few hairs, prolegs on segments 7, 8, and sometimes 9 rudimentary or absent.
The anal prolegs are very strong, and are furnished with numerous sharp hooklets, which retain the larva very firmly in its case.
The remaining segments are considerably thickened near the middle of the insect, rudimentary prolegs being present on the seventh, eighth, ninth, and tenth segments of the larva.
With regard to their larvae, the resemblance between the case-worms and the pseudo-caterpillars of the saw-flies seems to me very distant, and the numerousprolegs of the latter have scarcely a legitimate representative in the former.
When stilt prolegs unite so as to form only one leg bifid at its apex.
The legs and prolegs are tinged with pink, and sometimes the body is marked with pink.
The head and a plate on the next ring, also the legs, are shining black; the prolegs are blackish, tipped with yellowish.
The Drepanulidae are an allied family, in which the frenulum is usually present, while the hindmost pair of larval prolegs are absent, their segment being prolonged into a pointed process which is raised up when the caterpillar is at rest.
The larva in this family also is an exposed feeder, but it is remarkable in form, being flattened and slug-like, without prolegs and adorned with curious spinous processes.
Much discussion has taken place as to whether the abdominal prolegs are or are not developed directly from the embryonic abdominal appendages.
Geometridae, but distinguished by the absence of a frenulum in the moth and the presence of the normal ten prolegs in the larva.
The egg is flat, and the larval prolegs have complete circles of hooklets.
In the larva the prolegs on the hindmost segment are sometimes modified into pointed outgrowths which are carried erect when the caterpillar moves about.
The pupa has four or five movable segments, and the larval prolegs have complete circles of hooklets.
The two hinder pairs of prolegs are therefore alone functional and the larva progresses by "looping," i.
The larva is remarkable on account of its long feelers, the presence of pairs of jointed prolegs on the first eight abdominal segments, an anal sucker beneath the last segment and bladder-like outgrowths on the cuticle.
The sole, or part of the prolegs within the claws, is capable of opening and shutting.
In addition, in most cases, we find four pairs ofprolegs on the under side of the segments from the sixth to the ninth, and another pair on the last segment, which latter pair are called the anal prolegs.
The anal prolegs are widely divergent and elongated, as in many genera of the Satyrinoe.
There are various modifications of this scheme of foot-like appendages, only the larger and more highly developed forms of lepidoptera having as many pairs of prolegs as have been enumerated.
The feet are black, and the prolegs greenish-yellow.
But the greatest number of prolegs is to be found in the Brazil subcortical larva lately mentioned.
Where ten prolegs are present, as is the case in by far the greatest proportion of Lepidopterous larvae, there is constantly an anal pair, and a pair on each of the four intermediate segments just mentioned.
Claws nearly similar are found on the prolegs of some Dipterous larvae[297], but not in any of those of the other orders.
Long moveable claws also distinguish the singular prolegs before described[305] of another gnat (Tanypus maculatus Meig.
Two of the prolegs are anal, and the rest intermediate, and none are furnished with claws.
Prolegs only (many Tipulidae, and some subcutaneous Lepidopterous larvae, &c.
The dorsal prolegs of a species of Cynips described by Reaumur have been before noticed.
The prolegs deprived of claws are found in the larva of the Hymenopterous tribe of saw-flies (Tenthredo L.
Hymenopterous insects in which prolegs are present, have a variable number of these organs; some sixteen, as the saw-fly of the willow (T.
Reaumur thought he had seen one with eighteenprolegs upon Erysimum alliaria (v.
The abdominal segments are considerably thickened near the middle of the insect, rudimentary prolegs being present on the third, fourth, fifth, and sixth segments of the abdomen.
The larvae always possess a distinct head and six thoracic legs, and in addition a variable number of prolegs are often present on the abdominal segments.
There are in addition numerous fine, wavy lines down the back and sides of the larva, and the dorsal surface of the thoracic segments and ventral prolegs are bright reddish brown (Fig.
The head, legs, andprolegs are reddish-yellow, and the whole insect is more or less spotted with black.
The legs and prolegs are very small, and the latter are bright red in colour; a fleshy process which projects from the last segment of the larva is similarly coloured.
After the first month it becomes of a yellowish green; head, pale brown; feet and prolegs of nearly the same color.
The head and legs are chocolate brown, the prolegs reddish, and the first segment edged with pinkish color.
The caterpillar is of a green colour with slender yellowish lines along the back and sides; between the rings the colour inclines to yellowish, and the head, legs, and prolegsare reddish brown.
The caterpillar has the first and second pairs of prolegs very short, and below the brown-ringed spiracles there is a projecting ridge, fringed with a row of fleshy greenish-white filaments, some of which are forked.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "prolegs" in a variety of sentences. We hope that you will now be able to make sentences using this word.
