Helophilus Pendulus
''Helophilus pendulus'' is a European hoverfly. Its scientific name In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... means "dangling marsh-lover" (from Greek ''helo-'', "marsh", ''-phil'', "love", Latin ''pend-'', "hang"). It is a very common species in Britain, where it is the commonest ''Helophilus'' species. It is found throughout Europe from the Mediterranean to Scandinavia, westward to the Faroe Islands and Iceland, and through eastward through Russia from the Kola Peninsula south to Crimea and across Siberia to the Pacific Ocean. It also has the common name sun fly, although this is probably based on a mis-reading of ''helo-'' as ''helio-''.

Charles Howard Curran
Charles Howard Curran (20 March 1894 – 23 January 1972) was a Canadian entomologist who specialised in Diptera. Curran's main taxonomic interests were in brachyceran flies, particularly the flower flies Syrphidae, in which he described 723 species. From 1922 to 1928 he worked as a specialist service in Diptera Entomology of Canada. In 1928, he was hired by the American Museum of Natural History as Assistant Curator and, from 1947 until his retirement in 1960, as Curator of Insects and Spiders. In 1931, he donated his collection to that institution: it has 10,000 specimens representing about 1,700 species including 400 types. He received in 1933 a Doctorate of Science at the University of Montreal with a thesis entitled The Families and Genera of North American Diptera. He was vice-president of the New York Entomological Society The New York Entomological Society was founded in 1892. The Brooklyn Entomological Society merged with the Society in 1968.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoology, 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 Biological classification, 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 (school), gymnasium at Altona, Hamburg, Altona and entered the University of Copenhagen in 1762.

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 ...

Helophilus Fasciatus
''Helophilus fasciatus'' (Walker, 1849), the narrow-headed marsh fly, is an abundant species of syrphid fly observed throughout the United States and Canada. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametop .... The larvae of this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and farmyard manure or silage. The adults of this species lays eggs on vegetation overhanging water. The larvae hatch and drop into the water. References External links * Eristalinae Articles created by Qbugbot Insects descr ...
