	Johan Wilhelm Zetterstedt Johan Wilhelm Zetterstedt (20 May 1785 – 23 December 1874) was a Swedish naturalist who worked mainly on Diptera and Hymenoptera. Biography Zetterstedt studied at the University of Lund, where he was a pupil of Anders Jahan Retzius. He received the title of professor in 1822 and succeeded Carl Adolph Agardh as professor of botany and practical economy in 1836, retiring as emeritus in 1853. In 1831, he was elected a member of the Royal Swedish Academy of Sciences. He is best known as an entomologist. His collections of Scandinavian, Lapland and world Diptera and Orthoptera are in the Zoological Museum of the University of Lund. His students include Anders Gustaf Dahlbom.

	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 opini ...

	Muscidae Muscidae are a family of flies found in the superfamily Muscoidea. Muscidae, some of which are commonly known as house flies or stable flies due to their synanthropy, are worldwide in distribution and contain almost 4,000 described species in over 100 genera. Most species are not synanthropic. Adults can be predatory, hematophagous, saprophagous, or feed on a number of types of plant and animal exudates. They can be attracted to various substances including sugar, sweat, tearand blood. Larvae occur in various habitats including decaying vegetation, dry and wet soil, nests of insects and birds, fresh water, and carrion. The Housefly, housefly, ''Musca domestica'', is the best known and most important species. Some, from the genera ''Hydrotaea'' and ''Muscina'', are involved in forensic case studies.aces the linkCluichí Identifying characteristics The antennae are three-segmented and aristate; vein Rs is two-branched, a frontal suture is present, and the calypters are we ...

picture info	Palearctic The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

	Fauna Europaea Fauna Europaea is a database of the scientific names and distribution of all living multicellular European land and fresh-water animals. It serves as a standard taxonomic source for animal taxonomy within the Pan-European Species directories Infrastructure (PESI). , Fauna Europaea reported that their database contained 235,708 taxon names and 173,654 species names. Its construction was initially funded by the European Council (2000–2004). The project was co-ordinated by the University of Amsterdam The University of Amsterdam (abbreviated as UvA, nl, Universiteit van Amsterdam) is a public research university located in Amsterdam, Netherlands.

picture info	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]
picture info	Insects Described In 1845 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]
