Polyneoptera
The cohort Polyneoptera is one of the major groups of winged insects, comprising the Orthoptera (grasshoppers, crickets, etc.) and all other neopteran insects believed to be more closely related to Orthoptera than to any other insect orders. They were formerly grouped together with the Palaeoptera and Paraneoptera as the Hemimetabola or Exopterygota on the grounds that they have no pupa, the wings gradually developing externally throughout the nymphal stages. Many members of the group have leathery forewings ( tegmina) and hindwings with an enlarged anal field (vannus). When Carl Linnaeus started applying binomial names to animals in the 10th edition of his ''Systema Naturae'' in 1758, there were few animals included in the scheme, and consequently few groups. As more and more new species were discovered and differences recognised, the original groups proposed by Linnaeus were split up. Originally all polyneopteran insects were in the genus ''Gryllus'', this genus now con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neoptera
Neoptera (Ancient Greek ''néos'' ("new") + ''pterón'' ("wing")) is a classification group that includes most orders of the winged insects, specifically those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects (the " Palaeoptera" assemblage), which are unable to flex their wings in this way. Classification The taxon Neoptera was proposed by А.М. Martynov in 1923 and 1924, in the following classification: Pterygota *division Palaeoptera **order Odonata **order Agnatha (correct name: Ephemeroptera) **†order Dictyoneuridea **†order Megasecoptera **†order Meganisoptera **†order Protephemeroidea *division Neoptera **superorder Endopterygota ***order Coleoptera ***order Strepsiptera ***order Neuroptera ***order Raphidioptera ***order Megaloptera ***order Diptera ***order Mecoptera ***order Trichoptera ***order Lepidoptera ***order Hymenoptera **subdivision Polyneoptera ***superorder Orthopteroid ...

Zoraptera
The insect order (biology), order Zoraptera, commonly known as angel insects, contains small and soft bodied insects with two forms: winged with wings sheddable as in termites, dark and with eyes (compound) and ocelli (simple); or wingless, pale and without eyes or ocelli. They have a characteristic nine-segmented beaded (moniliform) antenna. They have mouthparts adapted for chewing and are mostly found under bark, in dry wood or in leaf litter. Description The name Zoraptera, given by Filippo Silvestri in 1913, is misnamed and potentially misleading: "zor" is Greek for pure and "aptera" means wingless. "Pure wingless" clearly does not fit the winged alate forms, which were discovered several years after the wingless forms had been described. The members of this order are small insects, or less in length, that resemble termites in appearance and in their gregarious behavior. They are short and swollen in appearance. They belong to the hemimetabolous insects. They possess man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermaptera
Earwigs make up the insect order Dermaptera. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings". Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs are found on all continents except Antarctica. Earwigs are mostly nocturnal and often hide in small, moist crevices during the day, and are active at night, feeding on a wide variety of insects and plants. Damage to foliage, flowers, and various crops is commonly blamed on earwigs, especially the common earwig '' Forficula auricularia.'' Earwigs have five molts in the year before they become adults. Many earwig species display maternal care, which is uncommon among insects. Female earwigs may care for their eggs; the ones that do will continue to watch over nymphs until ...

Embioptera
The order Embioptera, commonly known as webspinners or footspinners, are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. More than 400 species in 11 families have been described, the oldest known fossils of the group being from the mid-Jurassic. Species are very similar in appearance, having long, flexible bodies, short legs, and only males having wings. Webspinners are gregarious, living subsocially in galleries of fine silk which they spin from glands on their forelegs. Members of these colonies are often related females and their offspring; adult males do not feed and die soon after mating. Males of some species have wings and are able to disperse, whereas the females remain near where they were hatched. Newly mated females may vacate the colony and find a new one nearby. Others may emerge to search for a new food source to which the galleries can be extended, but in gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Wing
Insect wings are adult outgrowths of the insect exoskeleton that enable insect flight, insects to fly. They are found on the second and third Thorax (insect anatomy), thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the Odonata, dragonflies and Neuroptera, lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family (biology), family or even genus level in many order (biology), orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the win ...

Grylloblattodea
Grylloblattidae, commonly known as the icebugs or ice crawlers, is a family of extremophile (psychrophile) and wingless insects that live in the cold on top of mountains and the edges of glaciers. It is the only member of Grylloblattodea, which is generally considered an order. Alternatively, Grylloblattodea, along with Mantophasmatodea (rock crawlers), have been ranked as suborders of the order Notoptera. Grylloblattids are wingless insects mostly less than 3 cm long, with a head resembling that of a cockroach, with long antennae and having elongated cerci arising from the tip of their abdomen. They cannot tolerate warmth—most species will die at —and many species have small distribution ranges. Overview Grylloblattids, ice crawlers or icebugs puzzled the scientists who discovered them in 1914, E.M. Walker and T.B. Kurata; the first species named was '' Grylloblatta campodeiformis'', which means "cricket-cockroach shaped like a '' Campodea''" (a kind of two-pronged b ...

Paraneoptera
Paraneoptera or Acercaria is a Order (biology), superorder of insects which includes Psocodea, lice (Psocoptera, bark lice and Louse, true lice), thrips, and hemipterans, the true bugs. It also includes the extinct order Permopsocida, known from fossils dating from the Cisuralian, Early Permian to the mid-Cretaceous. All of the insects classified here exhibit various “reductions” or “simplifications” from the primitive body-plan found in typical polyneopterans. Cercus, Cerci, for example, are entirely absent in all living paraneopterans (Acercaria meaning without cerci). Other “reductions” occur in wing venation, in the number of tarsal segments (no more than three), only four Malpighian tubules, and only one complex of abdominal ganglia. The mouthparts of the Paraneoptera reflect diverse feeding habits. Basal groups are microbial surface feeders, whereas more advanced groups feed on plant or animal fluids. Phylogeny Paraneoptera consists of Psocodea (lice), along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exopterygota
The Exopterygota (Ancient Greek ''ἔξω'' (éxō, "outside") + ''πτερόν'' (pterón, "wing") + Neo-Latin ''-ota'' ("having")), also known as Hemimetabola, are a superorder of insects of the subclass Pterygota in the infraclass Neoptera, in which the young resemble adults but have externally developing wings. They undergo a modest change between immature and adult, without going through a pupal stage. The nymphs develop gradually into adults through a process of moulting. The Exopterygota are a highly diverse insect superorder, with at least 130,000 living species divided between 15 orders. They include cockroaches, termites, grasshoppers, thrips, lice and stick insects, among many other types of insects. Exopterygota are distinguished from the Endopterygota (or Holometabola) by the way their wings develop. Endopterygota (meaning literally "internal winged forms") develop wings inside the body and undergo an elaborate metamorphosis involving a pupal stage. Exopterygota ...

Dictyoptera
Dictyoptera (from Greek δίκτυον ''diktyon'' "net" and πτερόν ''pteron'' "wing") is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea (termites and cockroaches together) and the order Mantodea (mantises). All modern Dictyoptera have short ovipositors and typically lay oothecae. The oldest fossils of Dictyoptera from the Late Carboniferous, referred to as " roachoids" have long ovipositors and did not lay oothecae. The oldest modern oothecae-laying dictyopterans date to the Late Triassic. __TOC__ Classification and phylogeny The use of the term Dictyoptera has changed over the years, and while largely out of use for much of the last century, it is becoming more widely used. It has usually been considered a superorder, with Isoptera, Blattodea and Mantodea being its three orders. In some classifications, however, Dictyoptera is shifted to order status and in others the order Isoptera has been subsumed under Blattodea ...

Plecoptera
Plecoptera is an order (biology), order of insects commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. Their modern diversity, however, apparently is of Mesozoic origin. Plecoptera are found in both the Southern hemisphere, Southern and Northern Hemispheres, and the populations are quite distinct, although the evolutionary evidence suggests species may have crossed the equator on a number of occasions before once again becoming geographically isolated. All species of Plecoptera are intolerant of water pollution, and the presence of their nymph (biology), nymphs in a stream or still water is usually an indicator of good or excellent water ...

Mantophasmatodea
Mantophasmatidae is a family of carnivorous wingless insects within the monotypic order Mantophasmatodea, which was discovered in Africa in 2001. Recent evidence indicates a sister group relationship with Grylloblattidae (classified in the order Grylloblattodea), and Arillo and Engel have combined the two groups into a single order, Notoptera, with Grylloblattodea and Mantophasmatodea ranked as suborders. Overview The most common vernacular name for this order is gladiators, although they also are called rock crawlers, heelwalkers, mantophasmids, and colloquially, mantos. Their modern centre of endemism is western South Africa and Namibia ( Brandberg Massif), although the modern relict population of '' Tanzaniophasma subsolana'' in Tanzania and Eocene fossils suggest a wider ancient distribution. Mantophasmatodea are wingless even as adults, making them relatively difficult to identify. They resemble a cross between praying mantises and phasmids, and molecular evidence indi ...
