Allograpta Hastata
''Allograpta '' is a very large and diverse genus of hoverflies present throughout the world except most of the palearctic region. The adults are brightly coloured flower pollinators and most larvae have a predatory feeding mode involving soft-bodied sternorrhynchans. Certain species have diverged from this and their larvae have been found to be leaf-miners, stem-borers or pollen-feeders. ''Allograpta'' is currently being studied using both molecular and morphological methods to produce a robust phylogeny of the genus and its related genera. Preliminary studies show the genus to be monophyletic with the genera '' Sphaerophoria'' and '' Exallandra'' placed within which obviously complicates matters. A more complete review is needed before any major taxonomic changes can occur i.e. splitting the genus up or incorporating related genera, though the former subgenus '' Fazia'' was elevated to genus in 2020.Ximo Mengual, Gunilla Ståhls & Jeffrey H.

Allograpta Obliqua
''Allograpta obliqua'' is a common North American species of hoverfly, commonly known as oblique streaktail. The larvae are important predators of aphids while adults are Pollinator, pollinators. Description Adults are 6–7 mm long, with yellow stripes on the thorax and cross banding on the abdomen with four longitudinal, yellow stripes or spots on the fourth and fifth tergite. The face is yellow and lacks a complete median stripe. Males have Holoptic arrangement, holoptic eyes and females have Arthropod eye, dichoptic eyes. Eggs are white, oval, and about 0.84 mm in length. Larvae reach 8–9 mm. They are bumpy and slug-like. Life history Adults of ''A. obliqua'' occur throughout the year in the southern part of their range. Eggs are laid on surfaces leaves or branches near aphids. Larvae hatch in two to eight days and feed on the aphids. Distribution Found in most of the continental United States, Syrphidae of New York State, New York State. Quebec in Canada, ...

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pierre-Justin-Marie Macquart
Pierre-Justin-Marie Macquart (8 April 1778 – 25 November 1855) was a French entomologist specialising in the study of Fly, flies. 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. A second brother founded a botanic garden with a collection of over 3000 species of plants. Macquart, too became interested in natural history. In 1796, he joined the staff of General Armand Samuel then campaigning in the French Revolutionary Wars: Campaigns of 1796, Revolutionary Wars. He was a secretary and draftsman. The general staff was stationed in Schwetzingen, then Heidelberg, Mainz, Aa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Fly, 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, Saxony-Anhalt, 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 ...

Charles Howard Curran
Charles Howard Curran (20 March 189423 January 1972) was a Canadian entomologist who specialized in Diptera. Curran's main taxonomic interests were in brachyceran flies, particularly the flower flies Syrphidae, in which he described 723 species. He described 2,648 species over his career. He was active in the study of insect control. His 1934 work ''The Families and Genera of North American Diptera'' was an important and comprehensive work on the topic of North American fly genera. Biography Charles Howard Curran was born in Orillia, Ontario, in 1894. He was one of seven children, and preferred to go by his middle name Howard or his initials C. H. rather than Charles. He joined the Canadian Expeditionary Force and was sent to France to fight in World War I, serving from 1916 to 1918 as a machine gunner. Upon his return to Canada, he studied at the Ontario Agricultural College, gaining his bachelors degree in 1922. Continuing his story of entomology, he earned a Master ...

Afrotropical Realm
The Afrotropical realm is one of the Earth's eight biogeographic realms. It includes Sub-Saharan Africa, the southern Arabian Peninsula, the island of Madagascar, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropical realm, except for Africa's southern tip, has a tropics, tropical climate. A broad belt of deserts, including the Atlantic coastal desert, Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separates the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical and subtropical grasslands, savannas, and shrublands, tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands.
