Dimorphoxylota
''Xylota'' is a Holarctic genus of hoverflies similar in structure to the related genera '' Chalcosyrphus'' and ''Brachypalpoides''. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.

Chalcosyrphus
''Chalcosyrphus'' is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus ''Xylota'' but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic Xylophagy is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily (often solely) of wood. The word derives from Greek ''ξυλοφάγος'' (''xulophagos'') "eating wood", from ''ξύλον'' (') ... feeders in rotten wood in these habitats.

Xylota Segnis
''Xylota segnis'', The Brown-toed Forest Fly, is a common species of hoverfly. Etymology The genus name ''Xylota'' is the Latinized form of the rare Byzantine-Greek ξυλωτή sylōtēmeaning ''wooden'', while the Latin species name ''segnis'' means ''slipping'' or ''lazy'', as this hoverfly usually rests on a leaf and it does not fly frequently. The translation of the taxon could be "lazy wood fly". Distribution This species has a Palearctic and Nearctic distribution. It is present in all Europe including the Mediterranean, the Caucasus and through Russia to the Russian Far East and Japan. It is also present in the Nearctic eastern parts, in southeastern Canada and northeastern United States.GBIF species page, with map Habitat This species mainly inhabits low bushes in woods. Description Biology This species is polyvoltin, with up to three generations per year. Flight times last from April to September. Adults feed by grazing on anemophilous pollen grazed from surface ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...

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 dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylota Angustiventris
''Xylota angustiventris'', (Loew, 1866), the Two-spotted Leafwalker , is an uncommon species of syrphid fly observed in northeast North America. Syrphid flies are also known as Hover Flies or Flower Flies because the adults are frequently found hovering around flowers from which they feed on nectar and pollen. Adults are long, largely black with two yellow spots on the abdomen in the male? The larvae are not known, but in this genus, are likely to be found in tree holes or bark to feed on sap.

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 ins ...

Johannes C
Johannes is a Medieval Latin form of the personal name that usually appears as "John" in English language contexts. It is a variant of the Greek and Classical Latin variants (Ιωάννης, '' Ioannes''), itself derived from the Hebrew name '' Yehochanan'', meaning "Yahweh is gracious". The name became popular in Northern Europe, especially in Germany because of Christianity. Common German variants for Johannes are ''Johann'', ''Hannes'', '' Hans'' (diminutized to ''Hänschen'' or ''Hänsel'', as known from "''Hansel and Gretel''", a fairy tale by the Grimm brothers), '' Jens'' (from Danish) and '' Jan'' (from Dutch, and found in many countries).
