Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Hoverfly Genera
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mamma ...

Diptera Of Europe
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleksandr Stackelberg
Aleksandr Aleksandrovich Stackelberg (sometimes Shtakel'berg; russian: Александр Александрович Штакельберг; 1897–1975) was a Russian entomologist. Stackelberg was born in St. Petersburg and specialised on Diptera, notably Syrphidae. He joined the staff of the Zoological Museum of the Academy of Sciences in 1920, and in 1929 he was made the Director of the Diptera Division. From 1942 he was the Head of the Department of Entomology. He taught entomology to I. A. Rubtsov, B. B. Rohdendorf, Ye. N. Savchenko, and N. A. Violovitch. He wrote over 160 scientific papers.

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 ...

British Entomological And Natural History Society
The British Entomological and Natural History Society or BENHS is a British entomological society. It is based at Dinton Pastures Country Park in Reading. History BENHS was founded in 1872 as the South London Entomological and Natural History Society. Publications BENHS publishes a quarterly journal, the ''British Journal of Entomology and Natural History'' (), formally Proceedings and Transactions of the British Entomological and Natural History Society, and Proceedings and Transactions of the South London Entomological and Natural History Society. BENHS has published a number of books. Among the most well-known are two illustrated identification guides to British flies: * Stubbs, Alan E. and Steven J. Falk (1983) ''British Hoverflies, an illustrated identification guide'' * Stubbs, Alan E. and Martin Drake (2001) '' British Soldierflies and their allies'' Another title published by BENHS was ''New British Beetles - species not in Joy's practical handbook'' by Peter J.

George Henry Verrall
George Henry Verrall (7 February 1848 – 16 September 1911) was a British horse racing official, entomologist, botanist and Conservative Party (UK), Conservative politician. Horse racing Verrall was born in Lewes, Sussex. Following education at Lewes Grammar School he became secretary to his elder brother, John Frederick Verrall. John Verrall was a horse-racing official, being clerk of the course at many of the country's biggest meetings. When John died in 1877, George succeeded him.

Johann Wilhelm Meigen
Johann Wilhelm Meigen (3 May 1764 – 11 July 1845) was a German entomologist famous for his pioneering work on Diptera. Life Early years Meigen was born in Solingen, the fifth of eight children of Johann Clemens Meigen and Sibylla Margaretha Bick. His parents, though not poor, were not wealthy either. They ran a small shop in Solingen. His paternal grandparents, however, owned an estate and hamlet with twenty houses. Adding to the rental income, Meigen's grandfather was a farmer and a guild mastercutler in Solingen. Two years after Meigen was born, his grandparents died and his parents moved to the family estate. This was already heavily indebted by the Seven Years' War, then bad crops and rash speculations forced the sale of the farm and the family moved back to Solingen. Meigen attended the town school but only for a short time. He had learned to read and write on his grandfather's estate and he read widely at home as well as taking an interest in natural history.
