Platycleis Grisea
''Platycleis grisea''Fabricius JC (1781) ''Species Insectorum'' 1: 359. is a European species of Tettigoniinae, bush crickets described by Johan Christian Fabricius, Fabricius in 1781. It is the type species of the genus ''Platycleis'' and therefore the Tribe (biology), tribe Platycleidini. This species is recorded from mainland Europe (not the British Isles or Scandinavia) and northern Africa. Description and Biology ''P. grisea'' has body length of 15-24 mm and are usually quite uniformly coloured grey to light brown and marbled in a darker brown, with a lighter underside. The fore-wings are usually whitish and spotted. The side lobes of the pronotum are often patterned in a coarser brown and lined with a narrow, light colour and a central keel is apparent in the front half. The pronotum is rarely green or ivory-coloured on the upper side, but is often reddish. Like all representatives of the genus ''Platycleis'', the species is almost always long-winged, the wings clearly pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Tettigoniinae
The Tettigoniinae are a subfamily of bush crickets or katydids, which contains hundreds of species in about twelve tribes. Distribution The greatest diversity is in the Palaearctic region and many of the familiar European species of bush crickets (''e.g.'' in the genera ''Metrioptera, Pholidoptera, Platycleis'' and the type genus ''Tettigonia'') are in this subfamily. They are attributed to an ancient Gondwana fauna, which is reflected in the known distribution of the southern African genera, which are in turn related to Australian and North American genera in the tribe Nedubini (''e.g. Neduba'' and '' Aglaothorax''). Extant genera are native to: the Americas (where they may be called shield-backed katydids), Australia, southern Africa, Europe (especially Mediterranean), and the Near East. The faunas of the Neotropics and Australia are more closely related to one other than to those of southern Africa and Madagascar (in tribe Arytropteridini), although the three fauna ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Platycleis
''Platycleis'' is a genus of bush crickets described by Fieber in 1853, belonging to the subfamily Tettigoniinae. The species of this genus are present in Europe, North Africa and temperate Asia. Biology Studies conducted in 2010 at the University of Derby by Karim Vahed, Darren Parker and James Gilbert found that the tuberous bushcricket ('' Platycleis affinis'') has the largest testicle A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testoste ...s in proportion to body mass of any animal recorded. They account for 14% of the insect's body mass and are thought to enable a fast re-mating rate. '' Platycleis albopunctata'' is the grey bush cricket and occurs in the British Isles. Species The ''Orthoptera Species File'' lists the following accepted species: # '' Platycleis affinis'' Fieb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platycleidini
The Tettigoniinae are a subfamily of bush crickets or katydids, which contains hundreds of species in about twelve tribes. Distribution The greatest diversity is in the Palaearctic region and many of the familiar European species of bush crickets (''e.g.'' in the genera ''Metrioptera, Pholidoptera, Platycleis'' and the type genus ''Tettigonia'') are in this subfamily. They are attributed to an ancient Gondwana fauna, which is reflected in the known distribution of the southern African genera, which are in turn related to Australian and North American genera in the tribe Nedubini (''e.g. Neduba'' and '' Aglaothorax''). Extant genera are native to: the Americas (where they may be called shield-backed katydids), Australia, southern Africa, Europe (especially Mediterranean), and the Near East. The faunas of the Neotropics and Australia are more closely related to one other than to those of southern Africa and Madagascar (in tribe Arytropteridini), although the three faunas are rela ...

Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Platycleis Albopunctata
''Platycleis albopunctata'' is a species of European bush cricket in the tribe Platycleidini. This species occurs throughout Europe and in North Africa; several subspecies have been described (below). The nominate subspecies occurs in the British Isles The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, ... where it is often called the grey bush cricket. Description and Biology In mainland Europe, grey bush crickets can be confused with the very similar to '' P. grisea''. Their habitat includes areas with low and dry vegetation, such as sunny slopes and sandy open fields. The primary colour of the body is greyish to brownish, often with reddish brown elements on the upper side of the head and neck. The wings are long. ''P. albopunctata'' is omnivorous, eating both plants and smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genitalia
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs. Terminology The ''primary sex organs'' are the gonads, a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthoptera Of Europe
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).
