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 Natural History Museum, London, 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 [Gray] that the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, ...

Tachinidae
The Tachinidae are a large and variable family of true fly, flies within the insect order Fly, Diptera, with more than 8,200 known species and many more to be discovered. Over 1,300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all Zoogeography, zoogeographical regions and is especially diverse in South America. Taxonomy Just like that of all Diptera, the taxonomy of Tachinidae is complex. The name Tachinidae was first validly proposed by Robineau-Desvoidy in 1830, but in the form "Tachinariae." Robineau-Desvoidy, 1830 thus has priority despite the name correction, and this applies to Tachinidae (for the family) and to Tachininae (for the subfamily), in accordance with the ICZN rules on the formation of group names (Article 36.1). ...

Diptera Of North America
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing more than 150,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and the larvae, which lack true limb ...

Taxa Named By Francis Walker (entomologist)
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
