Daniel William Coquillett
Daniel William Coquillett (23 January 1856, Pleasant Valley, Ill. – 7 July 1911 Atlantic City, New Jersey) was an American entomologist who specialised in Diptera. He wrote a revision of the dipterous family Therevidae and many other scientific papers in which he described many new species and genera of Diptera. Coquillett was also the first to attempt fumigation with hydrocyanic acid as a means for controlling citrus scale insects. He experimented in the Wolfskill orange groves where he was supported by the foreman and later quarantine entomologist Alexander Craw Alexander Craw (3 August 1850 – 28 June 1908) was a pioneer American economic entomologist. He was the first American entomologist to work in quarantine protection against foreign pests arriving by ship to San Francisco, California. Along with ... in 1888–89.

Axel Leonard Melander
Axel Leonard Melander () was an American entomologist specialising in Diptera and Hymenoptera. His collection is shared between the German Entomological Institute and the National Museum of Natural History. Educational career He received his BS degree in 1901 and his MS degree on from the University of Texas at Austin and his ScD degree from Harvard University in 1914. His master's thesis was titled, "A monograph of the Empididæ of North America." He was a professor at Washington State University and retired as the chairman of the biology department of the City College of New York The City College of the City University of New York (also known as the City College of New York, or simply City College or CCNY) is a public university within the City University of New York (CUNY) system in New York City.

Empididae
__NOTOC__ Empididae is a family of flies with over 3,000 described species occurring worldwide in all the biogeographic realms but the majority are found in the Holarctic. They are mainly predatory flies like most of their relatives in the Empidoidea, and exhibit a wide range of forms but are generally small to medium-sized, non-metallic and rather bristly. Common names for members of this family are dagger flies (referring to the sharp piercing mouthparts of some species) and balloon flies. The term "dance flies" is sometimes used for this family too, but the dance flies proper, formerly included herein, are now considered a separate family Hybotidae. Description For terms see Morphology of Diptera. Empididae are small to medium-sized flies, rarely large (1.0 to 15.0mm.). The body is slender, or elongated and rarely thickset. The colour ranges from yellow to black, and they may be pollinose or lustrous, but never have a metallic gloss. The head is often small and rounded with ...

Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it “It is to him raythat the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, the publication of which beg ...

Hermann Loew
Friedrich Hermann Loew (19 July 1807 – 21 April 1879) was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States. Biography Early years Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a ''Geheimer Regierungsrath'' of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history. Teacher, tutor and husband Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empidoidea Genera
The Empidoidea are a large monophyletic superfamily of true flies, the sister taxon to the Muscomorpha (Cyclorrhapha). These two groups are sometimes united in the unranked taxon Eremoneura. There are some 10,000 known species within Empidoidea,Moulton & Wiegmann (2007) which are represented on all continents except Antarctica. They are known to have existed since the Jurassic period.Grimaldi & Engel (2005) Empidoidea has been subject to much debate regarding its phylogeny. Based on morphology alone, three major hypotheses had been proposed until 2007 and seemed to be consensus for some time—however, in 2018, Wahlberg & Johanson published the most current phylogeny supported by extensive genetic data, changing the relationship between quite a few families and tribes.Wahlberg & Johanson (2018) Description The majority of these insects are predatory, often with large compound eyes (sometimes covering almost the entire surface of the head), and tend to be associated with moist, t ...
