Hammerschmidtia
''Hammerschmidtia'' is a Holarctic genus of hoverflies whose larvae live in sap under the bark of freshly fallen trees. Diagnostics For terminology seSpeight key to genera and glossary The face of the male is tuberculate, with long hairs on the upper and lower sides of the lower three-quarters of the arista. Most of the hairs are several times longer than the arista. The scutum is armed with very evident spines, while the anepisternum, postalar callus, and scutellum have strong bristles. The abdomen is twice as long as the thorax, and the first posterior cell does not end acutely from the apex of the wing. The apical section of R4+5 is longer than the crossvein r-m, and the upper marginal cross-vein M1 is curved inwards where it meets R4+5. The legs are armed with spines and the anterior four tibiae terminate in a row of bristles. The femora are considerably swollen, especially the hind pair, which has numerous conspicuous spines below.

Theodor Emil Schummel
Theodor Emil Schummel (23 May 1786, Breslau—24 February 1848) was a German entomologist who specialised in Diptera. Schummel was a private tutor in Breslau. He was a member of Schlesische Gesellschaft für vaterländische Cultur (Silesian Society for Patriotic Culture) a largely scientific society which received royal ratification in 1809 after the draft of its constitution was sent to the government in Königsberg and published many of his shorter scientific papers on insects in the society's journal ''Übersicht der Arbeiten und Veränderungen der Schlesischen Gesellschaft für Vaterländische Kultur'', abbreviated ''Übers Arb.

Hammerschmidtia Ferruginea
''Hammerschmidtia ferruginea '', the Aspen hover fly, is a rare, species of Hoverfly, syrphid fly. It has been observed in Canada, Alaska and the northern United States. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving Nectarivore, nectar and protein-rich Palynivore, pollen. Larvae for this genus are of the rat-tailed maggot, rat-tailed type. ''Hammerschmidtia ferruginea'' larvae have been described by Rotheray. Description ''Hammerschmidtia ferruginea'' is a large (10–12 mm) orange-brown hoverfly with a feathered arista. It resembles ''Brachyopa'' and ''Hammerschmidtia'' was in the past a subgenus of ''Brachyopa''. In general appearance it is more like a Dryomyzidae, dryomyzid or Sciomyzidae, sciomyzid than a syrphid. The larva is illustrated in colour by Rotheray. Distribution Scotland east thro ...

Holarctic
The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula). These regions are further subdivided into a variety of ecoregions. Many ecosystems and the animal and plant communities that depend on them extend across a number of continents and cover large portions of the Holarctic realm. This continuity is the result of those regions’ shared glacial history. Major ecosystems Within the Holarctic realm, there are a variety of ecosystems. The type of ecosystem found in a given area depends on its latitude and the local geography. In the far north, a band of Arctic tundra en ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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, ...

British Entomological And Natural History Society
The British Entomological and Natural History Society or BENHS is a British entomological society. It is based at Dinton Pastures Country Park in Reading. History BENHS was founded in 1872 as the South London Entomological and Natural History Society. Publications BENHS publishes a quarterly journal, the ''British Journal of Entomology and Natural History'' (), formally Proceedings and Transactions of the British Entomological and Natural History Society, and Proceedings and Transactions of the South London Entomological and Natural History Society. BENHS has published a number of books. Among the most well-known are two illustrated identification guides to British flies: * Stubbs, Alan E. and Steven J. Falk (1983) ''British Hoverflies, an illustrated identification guide'' * Stubbs, Alan E. and Martin Drake (2001) '' British Soldierflies and their allies'' Another title published by BENHS was ''New British Beetles - species not in Joy's practical handbook'' by Peter J.

Annals Of The Entomological Society Of America
Annals ( la, annāles, from , "year") are a concise historical record in which events are arranged chronologically, year by year, although the term is also used loosely for any historical record. Scope The nature of the distinction between annals and history is a subject based on divisions established by the ancient Romans. Verrius Flaccus is quoted by Aulus Gellius as stating that the etymology of ''history'' (from Greek , , equated with Latin , "to inquire in person") properly restricts it to primary sources such as Thucydides's which have come from the author's own observations, while annals record the events of earlier times arranged according to years. White distinguishes annals from chronicles, which organize their events by topics such as the reigns of kings, and from histories, which aim to present and conclude a narrative implying the moral importance of the events recorded. Generally speaking, annalists record events drily, leaving the entries unexplained and equally we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
