Allograpta Hypoxantha
''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 cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Pierre-Justin-Marie Macquart
Pierre-Justin-Marie Macquart (8 April 1778 – 25 November 1855) was a French entomologist specialising in the study of Diptera. He worked on world species as well as European and described many new species. Biography Early years Macquart was born in Hazebrouck, France, in 1778 and died in Lille in 1855. 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, th ... [...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 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] |

Charles Howard Curran
Charles Howard Curran (20 March 1894 – 23 January 1972) was a Canadians, Canadian entomologist who specialised in Diptera. Curran's main taxonomic interests were in Brachycera, brachyceran flies, particularly the flower flies Syrphidae, in which he described 723 species. From 1922 to 1928 he worked as a specialist service in Diptera Entomology of Canada. In 1928, he was hired by the American Museum of Natural History as Assistant Curator and, from 1947 until his retirement in 1960, as Curator of Insects and Spiders. In 1931, he donated his collection to that institution: it has 10,000 specimens representing about 1,700 species including 400 types. He received in 1933 a Doctorate of Science at the University of Montreal with a thesis entitled The Families and Genera of North American Diptera. He was vice-president of the New York Entomological Society in 1936, president the following year. References Paul H. Arnaud Jr. et Thelma C. Owen (1981). Charles Howard Curran (1894-197 ...

Afrotropical Realm
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, 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 Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
