The feelers are inserted g' Its pale.
The feelers are very small and are often hidden in cavities beneath the head.
I got some ideas and I have a few feelers out, Fred answered, a defensive tone in his voice.
The head - carrying feelers, mandibles and two pairs of maxillae - is succeeded by the three thoracic segments, each bearing a pair of strong five-segmented legs, whose feet, like those of the adult, carry two claws.
Ten segments can be distinguished in the tapering abdomen, the ninth frequently bearing a pair of tail-feelers (cerci), and the tenth, attached ventrally to the ninth, having the anal opening at its extremity and performing the function of a posterior limb, supporting and temporarily fixing the tail end of the insect on the surface over which it crawls.
The beetles have feelers with eleven segments, whereof the terminal few are thickened so as to form a club.
The Rhipidophoridae are beetles with short elytra, the feelers pectinate in the malesandserrate in the females.
The feelers are branched and the jaws vestigial.
B and d, Head and feelers of male and female, more highly magnified.
The tenth abdominal segment carries a pair of jointed cerci which are often elongate, and the feelers are always long, while the jaws are usually feeble and membranous, though the typical parts of a mandibulate mouth are present - mandibles, maxillae with inner and outer lobes and palps, and second maxillae (labium) whose lacinae are not fused to form a ligula.
The feelers are long and simple, and the wings are very narrow, each with a sub-costal, a radial, a median and a cubital nervure; the branches of the median and the cubital, however, as well as the anal nervures, are vestigial, and there are a few short cross-bars between After Marlatt, Ent.
The feelers of these insects are elongate and thread-like, consisting of from a dozen to nearly thirty segments.
- Head of Aeolothrips fasciata, face view, showing eyes, bases of feelers and jaws.
Side, being scooped in bubbles by the terminal segments of the feelers when the insect rises to the surface.
39) have jointed, flexible palps, feelers - often of excessive length - with a short basal segment, and the three terminal segments forming a club, and, in some genera, larvae with legs.
The head of an ant carries a pair of elbowed feelers, each consisting of a minute basal and an elongate second segment, forming the stalk or "scape," while from eight to eleven short segments make up the terminal "flagellum."
Ants invite one another to work, or ask for food from one another, by means of pats with the feelers; and they respond to the solicitations of their guest-beetles or mites, who ask for food by patting the ants with their feet.
Elaboration in the form of the feelers, often a secondary sexual character in male insects, may result from a distal broadening of the segments, so that the appendage becomes serrate, or from the development of processes bearing sensory organs, so that the structure is pinnate or feather-like.
The brain innervates the eyes and feelers, and must be regarded as a " syncerebrum " representing the ganglia of the three foremost limb-bearing somites united with the primitive cephalic lobes.
This type of active, armoured larva - of ten bearing conspicuous feelers on the head and long jointed cercopods on the tenth abdominal segment - was styled campodeiform by F.
(The feelers and legs are cut short.) years; (2) certain stages of the life that are naturally " resting stages " may be in exceptional cases prolonged, and that to a very great extent; in this case no food is taken, and the activity of the individual is almost nil; (3) the life of certain insects in the adult state may be much prolonged if celibacy be maintained; a female of Cybister roeselii (a large water-beetle) has lived five and a half years in the adult state in captivity.
The Natal invaders fell back to the mountains which enclose the north of the colony; Oliver and Schoeman retired from Cape Colony before the small forces of Gatacre and Clements; and the presidents of the republics, realizing that the British Empire was capable of more resistance than they had calculated upon, put forward feelers aiming at the restoration of the status quo before the war.
Apart from these characteristics, the most distinctive feature of earwigs is the presence at the end of the abdomen of a pair of pincers which are in reality modified appendages, known as cercopods, and represent the similar limbs of Japyx and the caudal feelers of Campodea and some other insects.
In the form of the feelers, the wing-neuration and minor structural details there is much diversity among the saw-flies.
The feelers with twelve to fifteen segments are thread-like and straight.
The head varies greatly in shape, and the feelers have usually but few segments - often only four or five.
The feelers are elongate and conspicuous.
The Coreidae have a smaller scutellum, and the feelers are inserted high on the head, while in the Lygaeidae they are inserted lower down.
The Capsidae are a large family of rather soft-skinned bugs mostly elongate in form with the two basal segments of the feelers stouter than the two terminal.
The Naucoridae and Belostomatidae are flattened insects, with four-segmented feelers and fore-legs inserted at the front of the prosternum.
The feelers have one or more thickened basal segments, while the remaining segments are slender and threadlike.
Have the head with two ocelli and three-segmented feelers; frequently as in the tropical " lantern-flies " (q.v.) the head is prolonged into a conspicuous bladder, or trunk-like process.
On the other hand, the reduced feelers, the numerous Malpighian tubes (40), the large complex eyes, the vestigial condition of the jaws, the excessive size of the fore-wings as compared with the hind-wings and their complex neuration with an enormous number of crossnervules are all specializations.
A, Beetle; b, head of beetle with feelers and palps; c, larva; d, pupa.
The Lymexylonidae, a small family of this group, characterized by its slender, undifferentiated feelers and feet, is believed by Lameere to comprise the most primitive of all living beetles, and Sharp lays stress on the undeveloped structure of the tribe generally.
This is a somewhat heterogeneous group, most of whose members are characterized by clubbed feelers and simple, unbroadened tarsal segments - usually five on each foot - but in some familie andenera the males have less than the normal number on the feet of one pair.
The bestknown family is the Hydrophilidae, in which the feelers are short with less than eleven segments and the maxillary palpi very long.
The Cerambycidae, or longhorn beetles, are recognizable by their slender, elongate feelers, which are never clubbed and rarely serrate.
The feelers are usually longer in the male than in the female, exceeding in some cases by many times the length of the body.
- The Rhynchophora are a group of beetles easily recognized by the elongation of the head into a beak or snout, which carries the feelers at its sides and the jaws at its tip. The third tarsal segment is broad and bi-lobed, and the fourth is so small that the feet seem to be only four-segmented.
Their recollection of his conduct during the congress of Chatillon was the determining fact at this crisis; his professions at Lyons or Paris had not the slightest effect; his efforts to detach Austria from the coalition, as also the feelers put forth tentatively by Fouche at Vienna, were fruitless.
The head of an insect carries usually four pairs of conspicuous appendages - feelers, mandibles and two pairs of maxillae, so that the presence of four primitive somites is immediately evident.
In the more generalized insects the abdomen evidently consists of ten segments, the hindmost of which often carries a pair of tail-feelers, (cerci or cercopods) and a terminal anal segment.
They are abundantly distinct, however, through the short feelers with only three to five segments and the conspicuous prothorax.
The winged insects resemble the May-flies in their short feelers and in the large number (50 to 60) of their Malpighian tubes, but differ most strikingly from those insects in their strong wellarmoured bodies, their powerful jaws adapted for a predaceous manner of life, and the close similarity of the hind-wings to the forewings.
Structurally the Neuroptera are distinguished by elongate feelers, a large, free prothorax, a labium with the inner lobes of the second maxillae fused together to form a median ligula, membranous, net-veined wings without hairy covering, those of the two pairs being usually alike, the absence of abdominal cerci, and the presence of six or eight Malpighian tubes.
The Myrmeleonidae are large insects with short clubbed feelers on their prominent heads, and two pairs of closely similar net-veined wings, with regular oblong areolets at the tips.
The same is the case with the allied Ascalaphidae, which are distinguished from the Myrmeleonidae by their elongate feelers - as long as the body - and by the irregular apical areolets of the wings.
