Eduard Becher
Eduard Becher (30 September 1856, Vienna - 11 November 1886, Vienna) was an Austrian entomologist who worked on Diptera. He was the author of an article entitled 'Zur Kenntnis der Kopfbildung der Dipteren' ("Contribution to the knowledge of the head formation of the Diptera") ''Wiener Entomologische Zeitung'', 1: 49-54 (1882). In this he identified the divisions of the ''Cyclorrhapha'', '' Aschiza'' and ''Schizophora'', a division he based on differences in the frontal region of the head. ''Aschiza'' have no ptilinum or associated suture, ''Schizophora'' have both ptilinum and its suture. Becher's collection of Austrian Diptera is in the Naturhistorisches Museum The Natural History Museum Vienna (german: Naturhistorisches Museum Wien) is a large natural history museum located in Vienna, Austria.

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of th ...

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of int ...

Diptera
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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclorrhapha
Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called "Cyclorrhapha" ('circular-seamed flies') with reference to the circular aperture through which the adult escapes the puparium. This is a circumscriptional name that has significant historical familiarity, but in the present classification, this name is synonymous with the more recent "Muscomorpha The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera, and, most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blo ...". Cyclorrhapha underwent major adaptive radiation that led to the creation of over 72 000 species. These species share multiple attributes such as the 360-degree rotation of the male terminalia.

Aschiza
The Aschiza are a section of the Brachycera. Two large families, the Syrphidae and the Phoridae, and a number of smaller taxa are in this group. They are similar to most of the familiar Muscomorpha with one notable exception; they do not possess a ptilinum, so lack the prominent ptilinal suture on the face as in other muscoid flies. They do still have a puparium with a circular emergence opening, but it is not as precisely ellipsoid in shape as is typical for other muscoids. The term was first used by Eduard Becher Eduard Becher (30 September 1856, Vienna - 11 November 1886, Vienna) was an Austrian entomologist who worked on Diptera. He was the author of an article entitled 'Zur Kenntnis der Kopfbildung der Dipteren' ("Contribution to the knowledge of th ... . References External links Tree of Life.

Schizophora
The Schizophora are a section of true flies containing 78 families, which are collectively referred to as muscoids, although technically the term "muscoid" should be limited to flies in the superfamily Muscoidea; this is an example of informal, historical usage persisting in the vernacular. The section is divided into two subsections, the Acalyptratae and Calyptratae, which are commonly referred to as acalyptrate muscoids and calyptrate muscoids, respectively. The defining feature of the Schizophora is the presence of a special structure used to help the emerging adult fly break free of the puparium; this structure is an inflatable membranous sac called the ptilinum that protrudes from the face, above the antennae. The inflation of the ptilinum (using fluid hemolymph rather than air) creates pressure along the line of weakness in the puparium, which then bursts open along the seam to allow the adult to escape. When the adult emerges, the fluid is withdrawn, the ptilinum collap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptilinum
The ptilinum is an eversible pouch on the head, above the base of the antenna in schizophoran flies (a section of muscomorphan and cyclorrhaphan flies). It is used to force off the end of the puparium A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their ... in order for the fly to emerge, and after this inflation at emergence, the ptilinum collapses back inside the head, marked thereafter only by the ptilinal suture or frontal suture (which defines the aperture through which it everts).

Josef Mik
Josef Mik, also Joseph Mik (23 March 1839 in Zábřeh – 13 October 1900 in Vienna) was a Bohemian entomologist mainly interested in Diptera. He described many new species and made contributions to knowledge of the Diptera of Central Europe. Mik was the first dipterist to clarify the chaetotaxy of the legs. " On the legs I distinguish a front haeta and a hind-side ; an upper- and an under-side. When we imagine the leg stretched out horizontally and perpendicularly to the longitudinal axis of the body, the front-side is that which is turned towards the head, and the hind-sidethat turned towards the end of the body ; the upper- and under-side, in such a case, are self-understood."Mik, J. 1878 Dipterologische Untersuchungen Jahresber K.K. Akad. Gymnasium Vienna Mik was born in Zábřeh, Moravia. From 1871 to 1889 he was teacher at the Academic Gymnasium in Vienna. In 1889 he was given the Knight's Cross of the Order of Franz Joseph; he died in Vienna. Works * 1866 Beitrag zur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
