Tridactyloidea
Tridactyloidea is a superfamily in the order Orthoptera. The insects are sometimes known as pygmy mole crickets but they are Caelifera and not members of the mole cricket suborder Ensifera, unlike the true mole crickets, the Gryllotalpidae. It is composed of three families that contain a total of about 50 species. Insects in this superfamily can be 4 to 9 millimeters in length and generally have short antennae and long wings. They live along the banks of bodies of water in tropical areas and are good swimmers and jumpers. Fossils of this subfamily have been found in Siberian deposits dating back to the Cretaceous. Families According to thOrthoptera Species Filethere are three families: * Cylindrachetidae Giglio-Tos, 1914: "sandgropers" of Australia, Papua New Guinea and South America * Ripipterygidae Ripipterygidae is a family of insects in the order Orthoptera. Members of the family are commonly known as mud crickets. Description Ripipterygids are small, often dark-col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ripipterygidae
Ripipterygidae is a family of insects in the order Orthoptera. Members of the family are commonly known as mud crickets. Description Ripipterygids are small, often dark-colored, cricket-like orthopterans, between 3 and 14 mm in length. They closely resemble the related tridactylids. Like tridactylids, they have greatly expanded hind femora, and have the ability to swim and jump from the surface of water. They can be distinguished from tridactylids by their uninflated tibiae on the middle pair of legs, unsegmented cerci, rows of comblike teeth on the epiproct, and setae at the tips of the cerciform lobes on the paraproct, as well as through characters of the genitalia. Species in the genus ''Ripipteryx'' are typically black or dark brown and often metallic; many are boldly colored or strikingly patterned, with sharply contrasting white, yellow, and/or red markings. Members of the genus ''Mirhipipteryx'' are typically smaller and more drably colored. Distribution and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caelifera
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers ( Tetrigoidea) and pygmy mole crickets ( Tridactyloidea). The latter should not be confused with the mole crickets ( Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera. The name of this suborder comes from Latin meaning ''chisel-bearing'' ("chisel" in Latin: ''caelum''), referring to the "stout" shape of its species' ovipositors. Subdivisions and their distribution The Caelifera include some 2,400 valid genera and about 12,000 known species. Many undescribed species probably exist, especially in tropical forests. The Caelifera have a predominantly tropical distribution (as with most Orthoptera) with fewer species known from temperate climate zones. Caelifera are divided into two infraorders: the more basal Tridactylidea and the Acrididea or grasshopper-like species. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tridactylidae
The Tridactylidae are a family in the insect order Orthoptera. They are small, mole-cricket-like insects, almost always less than long when mature. Generally they are shiny, dark or black, sometimes variegated or sandy-coloured. They commonly live in short tunnels and are commonly known as pygmy mole crickets, though they are not closely related to the true "mole crickets" (Ensifera), as they are included in the Caelifera suborder (related to grasshoppers). Description The Tridactylidae are small members of the Orthoptera, most species being less than 10 mm in length, though some approach 20 mm. They have a wide, but patchy, distribution on all continents but Antarctica. Being so small and inconspicuously coloured, while living in shallow burrows in moist sandy soil, they are not generally familiar to non-entomologists. They have several unusual features, for example, the posterior femora are greatly enlarged, being strongly adapted for leaping; in some species thos ...

Orthoptera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a " stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek � ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensifera
Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera (grasshoppers and their allies) make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants. ''Ensifer'' is Latin for "sword bearer", and refers to the typically elongated and blade-like ovipositor of the females. Characteristics Characteristics shared by the two orthopteran suborders, Caelifera and Ensifera, are the mouthparts adapted for biting and chewing, the modified prothorax, the hind legs modified for jumping, the wing shape and venation, and the sound-producing strid ...

Gryllotalpidae
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera (grasshoppers, locusts, and crickets). Mole crickets are cylindrical-bodied, fossorial insects about long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and where they have arrived in new regions, may become agricultural pests. Mole crickets have three life stages: eggs, nymphs, and adults. Most of their lives in these stages are spent underground, but adults have wings and disperse in the breeding season. They vary in their diet: some species are herbivores, mainly feeding on roots; others are omnivores, including worms and grubs in their diet; and a few are largely predatory. Male mole crickets have an exceptionally loud song; they sing from a burrow that opens out into the air in the shape of an exponential horn. The song is an almost pure tone, modulated into chirps. It is used to attract females, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaspard Auguste Brullé
Gaspard Auguste Brullé (7 April, 1809 – 21 January, 1873) was a French entomologist. Passionate about insects from a young age and through the intervention of Georges Cuvier, he participated in the Morea expedition organised by Jean Baptiste Bory de Saint-Vincent in 1829. In 1832, he participated in the foundation of the Société entomologique de France. The following year he became an aide-naturaliste (assistant naturalist) to Jean Victoire Audouin in charge of Crustacea, Arachnida and insects. Brullé studied for and obtained a baccalauréat in sciences then in "lettres", before qualifying in 1839 as a Doctor of Natural Science. His thesis, published in 1837, was ''Sur le gisement des insectes fossiles et sur les services que l'étude de ces animaux peut fournir à la géologie''. He became the Professor of Zoology and Comparative Anatomy at the University of Dijon. He proposed a new classification of Neuroptera which was completed by Wilhelm Ferdinand Erichson. He a ...

Cylindrachetidae
Sandgropers are wholly subterranean apterous insects of the family Cylindrachetidae that may grow up to 7 cm (3 in) long. Three genera are currently recognised: '' Cylindracheta'', '' Cylindraustralia'' and '' Cylindroryctes''. Like many subterranean animals, little is known about their habits and diet, but Western Australian farmers have blamed them for substantial crop losses. Sandgropers were once thought to be degenerate mole crickets, but they are now known to be more closely related to pygmy mole crickets, in the Caelifera, which includes grasshoppers. Although widely believed to be herbivorous, some have been found with animal remains in their gut. Range * Australia: **''Cylindracheta'' is found only in the Northern Territory **''Cylindraustralia'' widely except in the south-east and Tasmania ***six species have been recorded in Western Australia of which five are believed to be endemic to that state. ''C. kochii'' and ''C. tindalei'' are found in the Perth re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Superfamilies
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. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
