Sciaroidea Genera
Sciaroidea is a superfamily in the infraorder Bibionomorpha. There are about 16 families and more than 15,000 described species in Sciaroidea. Most of its constituent families are various gnats. Description As nematoceran flies, sciaroid adults generally have long segmented antennae, while their larvae have a well-developed head and mouthparts. Aside from this, sciaroids vary in appearance. For example, Sciaridae adults have each eye extended dorsally to form an "eye bridge", a feature not found in related families. Cecidomyiidae adults have a distinctive reduced wing venation, while their larvae are atypical for nematoceran larvae in having a very small head capsule. Ecology Most fungus gnats (Sciaroidea excluding Cecidomyiidae) live in forests with their larvae occurring in fungi, dead wood and soil. There are some which live in wetlands such as fens. Several genera of Sciaridae and Mycetophilidae may reach high abundances in damp buildings with wet organic matter. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hessian Fly
The Hessian fly or barley midge, ''Mayetiola destructor'', is a species of fly that is a significant pest of cereal crops including wheat, barley and rye. Though a native of Asia, upon its discovery it was believed to have been transported into North America in the straw bedding of Hessian troops during the American Revolution (1775–1783), thus the origin of its common name. However, the report of an inquiry made in 1788 by Sir Joseph Banks states that "no such insect could be found to exist in Germany or any other part of Europe". Nonetheless, it appears that this species, or one exactly like it in habits, had been known for at least a century prior to the American revolution from a locality near Geneva, and also for a long time from some regions in France. There are usually two generations a year but may be up to five. In the spring the dark-coloured female lays about 250 to 300 reddish eggs on plants, usually where the stems are covered by leaves; the larvae feed on the sa ...

Boris Rohdendorf
Boris Borisovich Rohdendorf (russian: link=no, Борис Борисович Родендорф, 12 July 190421 November 1977) was a Soviet entomologist and curator at the Zoological Museum at the University of Moscow. He attained the position of head of the Laboratory of Arthropods, Paleontological Institute of Russian Academy of Sciences, Academy of Sciences of the USSR (now Russian Academy of Sciences) in Moscow. A student of Andrey Martynov, he was a prolific taxonomist who described numerous new taxa, including fossil Diptera Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing".

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gustaf Johan Billberg
Gustaf Johan Billberg (14 June 1772, Karlskrona – 26 November 1844, Stockholm) was a Swedish botanist, zoologist and anatomist, although professionally and by training he was a lawyer and used science and biology as an avocation. The plant genus ''Billbergia'' was named for him by Carl Peter Thunberg. Biography In 1790 he earned his legal degree at the University of Lund, later working as an auditor at the audit chamber in Stockholm from 1793. In 1798 he became a member of the county administrative board (''landskamrerare'') in Visby. In 1808 he returned to Stockholm, where from 1812 to 1837, he served as a member of the administrative court (''kammarrättsråd''). He was promoted in 1824 to head the ministry of the Board of Customs (''generaltullstyrelsen''). In 1812, he purchased the right of publishing to the precious work of ''Svensk Botanik'' from the estate of Johan Wilhelm Palmstruch. He subsequently prepared two parts for publication during 1812–1819. He was elected m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sciaridae
The Sciaridae are a family of flies, commonly known as dark-winged fungus gnats. Commonly found in moist environments, they are known to be a pest of mushroom farms and are commonly found in household plant pots. This is one of the least studied of the large Diptera families, probably due to the small size of these insects and the similarity among species. Currently, around 1700 species are described, but an estimated 20,000 species are awaiting discovery, mainly in the tropics. More than 600 species are known from Europe. Description Adult Sciaridae are small, dark flies 1-11 mm long and usually <5 mm long. They have a characteristic wing venation: there is no cross vein except for a short rs at the wing base, the anterior veins are a short R1 and a long R5, vein M has a simple fork with a long stem, and CuA1 has a fork with a short stem. Larval Sciaridae are slender and lack legs. They are white except for a black head, and their skin is slightly transpa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rangomaramidae is a family of flies in the infraorder Bibionomorpha. The family, members of which are known as long-winged fungus gnats, was erected in 2002 by Jaschhof and Didham to include five new species of flies in the genus ''Rangomarama ''Rangomarama'' is a genus of fungus gnats in the family Ditomyiidae The Ditomyiidae are a small (90 species) family of flies (Diptera).They are found worldwide (except in the Afrotropical Region), most species are found in the Australasian an ...'' from New Zealand.

Mycetophilidae
The Mycetophilidae are a family of small flies, forming the bulk of those species known as fungus gnats. About 3000 described species are placed in 150 genera, but the true number of species is undoubtedly much higher. They are generally found in the damp habitats favoured by their host fungi and sometimes form dense swarms. Adults of this family can usually be separated from other small flies by the strongly humped thorax, well-developed coxae, and often spinose legs, but identification within the family between genera and species generally requires close study of microscopic features such as subtle differences in wing venation and variation in chaetotaxy and 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, a ....

Frederick Wallace Edwards
Frederick Wallace Edwards FRS (28 November 1888 in Fletton, Peterborough – 15 November 1940 in London), was an English entomologist. Edwards was known in the field of entomology for his work on Diptera. Edwards worked in the British Museum (Natural History) which contains his collections made on his expeditions to Norway and Sweden (1923), Switzerland and Austria (1925), Argentina and Chile (1926/27), with Raymond Corbett Shannon, Corsica and USA (1928), the Baltic (1933), Kenya and Uganda (1934), with Ernest Gibbins, and the Pyrenees (1935). He was able to oversee publication of Alwyn M. Evan's monograph on ''The Mosquitoes of the Ethiopian Region'' after her death in 1937. Among the unusual insects that he described was the flightless marine midge ''Pontomyia''. The mosquito genus ''Fredwardsius'' is named to honor his work establishing the generic and subgeneric framework which forms the basis for modern day systematics of the Culicidae Mosquitoes (or mosquitos) ...
