Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Toxomerus Calceolatus
''Toxomerus'' is a very large genus of hoverflies. They are found in many parts of North and South America. Most larvae are predators on soft bodied insects, though a few species have been shown to feed on pollen. Adults feed on the pollen of a wide range of flowers. Morphology The majority of species are 6–9 mm in length. However, the largest, ''Toxomerus insignis'', found throughout the Northeastern part of North America, is 13 mm long. A common trait of species within the genus is their mimicry of stinging Hymenoptera to avoid predators.Penney, Heather D., et al. "The relationship between morphological and behavioral mimicry in hover flies (Diptera: Syrphidae)." ''The American Naturalist'' 183.2 (2013): 281-289. What distinguishes ''Toxomerus'' from other hoverflies is the posterior indentation of their eyes and unique abdominal patterns; the abdominal patterns are diagnostic at the species level within the genus. Eyes are large (taking up approximately 2/3 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Howard Curran
Charles Howard Curran (20 March 1894 – 23 January 1972) was a Canadians, Canadian entomologist who specialised in Diptera. Curran's main taxonomic interests were in Brachycera, 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 in 1936, president the following year. References Paul H. Arnaud Jr. et Thelma C. Owen (1981). Charles Howard Curran (1894-197 ...

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 ...
