Notoptera
The wingless insect order Notoptera, a group first proposed in 1915, had been largely unrecognized since its original conception, until resurrected in 2004. As now defined, the order comprises five families, three of them known only from fossils, two known from both fossil and living representatives, and fewer than 60 known species in total. History of research The name was originally coined in 1915 for a group of fossil orthopteroids, and largely forgotten until it was resurrected and redefined ("Notoptera Crampton ''sensu novum''") by Engel and Grimaldi in 2004 (after the discovery of living Mantophasmatidae), who recommended to give a single order that includes both the living and fossil representatives of the lineage. Terry and Whiting in 2005 independently proposed a new name, "Xenonomia", for the same lineage of insects (including the Grylloblattodea and Mantophasmatodea). In 2006, Cameron, Barker, and Whiting studied the mitochondrial genomics of the Mantophasmatodea, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mantophasmatidae
Mantophasmatidae is a family (biology), family of carnivorous wingless insects within the order Notoptera, which was discovered in Africa in 2001.K.-D. Klass, O. Zompro, N.P. Kristensen, J. Adis. Mantophasmatodea: a new insect order with extant members in the afrotropics Science, 296 (2002), pp. 1456–1459Adis, J., O. Zompro, E. Moombolah-Goagoses, and E. Marais. 2002.

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. They belong, along with Mantophasmatidae (rock crawlers), to 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 10 °C) 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 bristletail). Most are nocturnal and appear to feed on detritus. They have long antennae (23–45 segments) and long cerci (5†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insect Orders
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grylloblatta Campodeiformis
''Grylloblatta campodeiformis'', also known as the northern rock crawler, is an omnivorous species of insect in family Grylloblattidae. Like other species in the genus '' Grylloblatta'', it is endemic to North America. Taxonomy This species was the first grylloblatid discovered and formally described in the scientific literature by Edmund Walker in 1914. It was originally placed in the order Orthoptera but has since been placed in the order Notoptera. There are currently four subspecies: * ''Grylloblatta campodeiformis athapaska'' Kamp, 1979, recorded in British Columbia, Alberta, and Montana * ''Grylloblatta campodeiformis campodeiformis'' Walker, 1914, recorded in British Columbia * ''Grylloblatta campodeiformis nahanni'' Kamp, 1979, recorded in British Columbia * ''Grylloblatta campodeiformis occidentalis'' Silvestri, 1931, recorded in Washington state, US Description Adults are typically long, excluding ovipositors and cerci, and are fairly elongate, wingless insects. ...

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial Genome
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Orthopteroid
Orthopteroids are insects which historically would have been included in the order Orthoptera and now may be placed in the Polyneoptera. 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 orthopteroid insects were in the genus ''Gryllus'', this genus now contains a group of closely related crickets. In the scheme used by Linnaeus the genus contained crickets, grasshoppers, locusts, katydids / bush crickets (Tettigoniidae), stick insects, and praying mantises. These groups, along with the cockroaches, which Linnaeus did treat differently, are all orthopteroid insects.Nichols, S.W. (1989)''The Torre-Bueno Glossary of Entomology''.
