Acrocerinae
Acrocerinae is a subfamily of Acroceridae. They are small distinctive flies whose larvae are endoparasites of spiders. Adult hunchback-flies visit flowers to feed on nectar. Traditionally the subfamily included the genera now placed in Cyrtinae and Ogcodinae Ogcodinae is a subfamily of the Acroceridae (small-headed flies). Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae The Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two mai ..., but the subfamily in this sense was found to be polyphyletic and was split up in 2019.

Acroceridae
The Acroceridae are a small family (biology), family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common names are small-headed flies or hunch-back flies. Many are bee or wasp mimicry, mimics. Because they are parasitoids of spiders, they also are sometimes known as spider flies. Description The Acroceridae vary in size from small to fairly large, about the size of large bees, with a wingspan over 25 mm in some species. As a rule, both sexes have tiny heads and a characteristic hump-backed appearance because of the large, rounded thorax. In appearance, they are compact flies without major bristles, but many species have a bee-like hairiness on their bodies, and some are bee or wasp mimicry, mimics. In most species, the eyes are holoptic in both sexes, the heads seemingly composed mainly of the large ommatidia, facete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmacyrtus
''Burmacyrtus'' is an extinct genus of small-headed flies of uncertain placement. The genus is known from Upper Cretaceous fossils in amber from Myanmar Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, Joh .... It contains only one species, ''Burmacyrtus rusmithi''. The genus was originally placed in the family Acroceridae, though was later reassessed and considered not to be an acrocerid. Instead, it could possibly be a stem group acrocerid or placed in Heterodactyla. The generic name is a combination of "Burma" (another name for Myanmar) and '' Cyrtus'', an extant genus. The species is named in honor of R.D.A. Ru Smith, who donated the holotype to the AMNH from his personal collection.

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.

Brachycera Subfamilies
The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. Description A summary of the main physical characteristics is: * Antenna size (with eight or fewer flagellomeres) is reduced. * The maxillary palp (an elongated appendage near the mouth) has two segments or fewer. * The back portions of the larval head capsule extend into the prothorax (the anterior part of the thorax, which bears the first pair of legs). * Two distinct parts make up of the larval mandible (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the labrum (the roof of the mouth). * The configuration of the CuA2 and A1 wing veins is distinct. Brachyceran flies can also be distinguished through behavior. Many of the species are predators or scavengers. Classification The structure of subgroups with ...

Carvalhoa (fly)
''Carvalhoa'' is a genus of small-headed flies in the family Acroceridae. The genus is endemic to Chile. It was originally known as ''Sphaerops'', named by Rodolfo Amando Philippi in 1865. This name was found to be preoccupied by the reptile genus ''Sphaerops'' Gray, 1845, so it was renamed to ''Carvalhoa'' by Ahmet Ömer Koçak and Muhabbet Kemal in 2013. The genus is named after the Brazilian dipterist Claudio José Barros de Carvalho. Unlike the larvae of other acrocerids, which are endoparasitoids (internal parasitoids) of spiders, the larvae of ''Carvalhoa appendiculata'' can develop as ectoparasitoids (external parasitoids) on their host spiders. Species *'' Carvalhoa appendiculata'' (Philippi Philippi (; grc-gre, Φίλιπποι, ''Philippoi'') was a major Greek city northwest of the nearby island, Thasos.

William Elford Leach
William Elford Leach Royal Society, FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Royal Devon and Exeter Hospital, Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating Doctor of Medicine, MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Museum, London, Natural History Department of the British Museum, where he had responsibility for the zoological ...
