Platycheirus (subgenus)
''Platycheirus '' is a large genus of hoverfly, hoverflies. They are also called sedgesitters. The genus ''Platycheirus'' was established in 1828 by Lepeletier and Serville, with the type specimen of ''Syrphus scutatus'' Meigen. This genus is primarily Holarctic in distribution, encompassing 70 species within the Nearctic region. Notably, at least 23 of these Nearctic species are also found in the Palearctic realm, with their approximately 110 species.The distribution of ''Platycheirus'' is markedly Subarctic climate, boreal, with half of the 70 Nearctic species in the Yukon, Northwest Territories, or Alaska. The genus is widespread from Mexico, Central and South America, Europe, Asia, Southeast Asia, ''Platycheirus'' are not found in Australia, Indonesia and New Guinea. The genus has a variety of food choices for larvae, ranging from generalized aphid predators to species that specialize in feeding on one or two specific aphid species. Most are feeding within the ground layer of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Platycheirus confusus'', the Confusing Sedgesitter, is a common species of syrphid fly in the family Syrphidae. It has been found to have and eastern and western North American population. Larvae have been successfully reared on a diet of ''Adelges piceae''.

The legs are mostly dark, with only the tips of the femora and the basal three-quarters of the fore and mid tibiae being orange. On the upper two-thirds of the fore tibia, there is a row of weak, posterior setae, with the longest setae being approximately three times the diameter of the tibia. The mid tibia a ...

Juan Fernández Islands
The Juan Fernández Islands () are a sparsely inhabited series of islands in the South Pacific Ocean, reliant on tourism and fishing. Situated off the coast of Chile, they are composed of three main volcanic islands: Robinson Crusoe Island, Robinson Crusoe, Alejandro Selkirk Island, Alejandro Selkirk, and Santa Clara Island, Santa Clara. The group is part of Insular Chile. The islands are primarily known for having been the home to the marooning, marooned sailor Alexander Selkirk for more than four years from 1704, which may have inspired English writer Daniel Defoe's ''Robinson Crusoe''. Most of the archipelago's present-day inhabitants reside on Robinson Crusoe Island, and mainly in the capital, San Juan Bautista, Chile, San Juan Bautista, located at Cumberland Bay on the island's north coast.The islands' area and population data retrieved from the 2012 census. The group of islands is part of Chile's Valparaíso Region (which also includes Easter Island) and, along with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Edward Collin
James Edward Collin (16 March 1876, Kirtling – 16 September 1968) was an English entomologist who specialised in Diptera. He was the author of ''Empididae''. ''British Flies'', Volume 6. University Press, Cambridge (1961). This was the third volume in an uncompleted series begun by his uncle George Henry Verrall. Collin wrote extensively on Diptera of most families of Diptera (excepting those in Nematocera). The specimens collected by Collin and his uncle Verrall are in the Hope Entomological Collections at the University of Oxford. The Oxford University Museum of Natural History's website provides a searchable database of the new species they described. He was a Fellow of the Royal Entomological Society The Royal Entomological Society is a learned society devoted to the study of insects. It aims to disseminate information about insects and to improve communication between entomologists. The society was founded in 1833 as the Entomological S ... and its preside ...

He worked on world species as well as European and described many new species. Biography Early life Macquart was born in Hazebrouck, on 8 April 1778. He was interested in natural history from an early age due to his older brother who was an ornithologist and a Fellow of the Société de Sciences de l’Agriculture et des Arts de la Ville de Lille and whose bird collection became the foundation of the societies museum, the Musée d'Histoire Naturelle de Lille.
