Volucella Pellucens - 2012-07-24
''Volucella'' is a genus of large, broad-bodied, dramatic hover-flies. They have distinctive plumose aristae and the face is extended downward. They are strongly migratory and males are often territorial. Adults feed on nectar of flowers and are often seen sunning on leaves. The larvae of most species live in nests of bumblebees and social wasps, where they are detritivores and larval predators.

Volucella Pellucens
''Volucella pellucens'', the pellucid fly, is a hoverfly. Distribution and habitat This species occurs in much of Europe, and across the Palearctic to Japan. The adult ''V. pellucens'' is usually found in woodlands and wooded hedgerows, but will enter gardens. Description ''Volucella pellucens'' is about 13–17 mm in length, with a wing length about 10–15.5 mm.Stuart Ball, S. G. Ball, Roger MorriBritain's Hoverflies: An Introduction to the Hoverflies of Britain/ref> These hoverflies have a broad, mainly black body, but the front part of their abdomens have a broad, yellow band, giving them the appearance of a bee or wasp. Their two wings are transparent, as with most flies, but the leading edge is amber, with a brown patch on each wing. The mimicry of bees or wasps in shape and colouration is shown by other hoverflies, which is thought to protect against falling prey to birds and other insectivores that avoid eating true wasps because of their stings.

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish 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 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 at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Volucella Inflata
''Volucella inflata'' is a large species of European hoverfly. Description ''V. inflata'' is a large, short-haired fly. Though a little smaller than most European species of ''Volucella'', typical body length is 12–15 mm and wing length is 11–13 mm. The thorax is black with orange margins, and the scutellum is orange with light-coloured hairs at the apex. The abdomen is largely black, with the exception of dark orange brown patches on the second tergite. Biology It is found mostly in deciduous forests with mature trees, though has been known to venture into domestic gardens. Adults fly from May to July and feed on nectar from flowers, mostly from umbellifers. Larvae inhabit social insect nests. Distribution This fly is very local over much of Europe, being found from Sweden and northern Germany, the Pyrenees and northern Spain, Britain, eastwards through Central Europe into European Russia and the Caucasus, and the former Yugoslavia and Bulgaria Bulgaria ...

Volucella Inanis
''Volucella inanis'' is a species of hoverfly belonging to the family Syrphidae. Distribution This species is present in most of Europe, in eastern Palearctic realm, in the Near East and in North Africa. Description The adults reach long. They have three yellow bands on an otherwise black abdomen and thus closely resemble wasps in a form of mimicry. The first two bands are completely or partially interrupted by a black wedge. The head has feather-like antennae and the wings have darkened patches in the middle and on the tip. Biology ''Volucella inanis'' can be encountered from early July to early September, feeding on flowers of species such as yarrow (''Achillea millefolium''), dill (''Anethum graveolens''), heather (''Erica'' species), thistles (genera '' Carduus'', ''Cirsium'', and ''Onopordum'') and ''Buddleja davidii''. The female lays eggs in the nests of social wasps and hornets (''Vespa crabro'', ''Vespula germanica ''Vespula germanica'', the European wasp, G ...

Volucella Facialis
''Volucella bombylans'' is a large species of hoverfly belonging to the family Syrphidae. Distribution This species is present in most of Europe, in the East Palearctic realm, in the Near East and in the Nearctic realm. Habitat These hoverflies can be found in forest edges and clearings, woodland margins, hedgerows, wet meadows, spruce forest edge and urban wasteland or gardens, usually sunning on leaves. Description ''Volucella bombylans'' is larger than most hoverflies, reaching a body length of 11 to 17 mm. and a wingspan length of 8–14 mm. They look something like a bumblebee with a furry black, yellow and/or white body, but they are given away by their heads, plumed antennae, large eyes and the particular wing venation, which make them quite easy to identify as a true fly, like a blowfly. The mesonotum bears black or yellow hairs on the sides, while the scutellum is brownish or yellowish. The wings are milky white with a dark cross-bands in the anterior hal ...

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 ...

Volucella Evecta
''Volucella evecta'', the eastern swiftwing, is an uncommon species of hoverfly that has been considered a subspecies of ''Volucella bombylans'', but has been shown to be a distinct species. This species is a bumblebee mimic. It resembles a number of species, including ''Bombus pensylvanicus'', '' Bombus affinis'', '' Bombus bimaculatus'', and '' Habropoda laboriosa''. The range of this species is from Eastern North America and Canada from Georgia to New Brunswick. The adults have been observed feeding on ''Geum'', ''Viburnum'', ''Rubus,'' and other flowering plants. Larvae of this species are not known, but larvae in this genus feed on the debris and larvae in bee and wasp nests. Description For terms see Morphology of Diptera. Size : Head :The frons is black with yellow pile The face is black to chestnut with yellow pile. In profile, the face is excavated below the antennae. The antennae has an elongate dark red flagellum with long densly plumose arista. The eyes are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Wendell Williston
Samuel Wendell Williston (July 10, 1852 – August 30, 1918) was an American educator, entomologist, and paleontologist who was the first to propose that birds developed flight cursorially (by running), rather than arboreally (by leaping from tree to tree). He was a specialist on the flies, Diptera. He is remembered for Williston's law, which states that parts in an organism, such as arthropod limbs, become reduced in number and specialized in function through evolutionary history. Early life Williston was born in Boston, Massachusetts to Samuel Williston and Jane A. Williston née Turner. As a young child, Williston's family travelled to Kansas Territory in 1857 under the auspices of the New England Emigrant Aid Company to help fight the extension of slavery. He was raised in Manhattan, Kansas, attended public high school there, and graduated from Kansas State Agricultural College (now Kansas State University) in 1872, afterwards receiving a Master of Arts from that instituti ...

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] |
