Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design an ...

Butterflies Described In 1881
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, ...

Consortium For The Barcode Of Life
The Consortium for the Barcode of Life (CBOL) was an international initiative dedicated to supporting the development of DNA barcoding as a global standard for species identification. CBOL's Secretariat Office is hosted by the National Museum of Natural History, Smithsonian Institution, in Washington, DC. Barcoding was proposed in 2003 by Prof. Paul Hebert of the University of Guelph in Ontario as a way of distinguishing and identifying species with a short standardized gene sequence. Hebert proposed the 658 bases of the Folmer region of the mitochondrial gene cytochrome-C oxidase-1 as the standard barcode region. Hebert is the Director of the Biodiversity Institute of Ontario, the Canadian Centre for DNA Barcoding, and the International Barcode of Life Project (iBOL), all headquartered at the University of Guelph. The Barcode of Life Data Systems (BOLD) is also located at the University of Guelph. CBOL was created in May 2004 with support of the Alfred P. Sloan Foundation ...

Acraea (butterfly)
''Acraea'' is a genus of brush-footed butterflies (family Nymphalidae) of the subfamily Heliconiinae. It seems to be highly paraphyletic and has long been used as a "wastebin taxon" to unite about 220 species of anatomically conservative Acraeini. Some phylogenetic studies show that the genus ''Acraea'' is monophyletic if '' Bematistes'' and Neotropical '' Actinote'' are included (see Pierre & Bernaud, 2009). Most species assembled here are restricted to the Afrotropical realm, but some are found in India, Southeast Asia, and Australia.Silva-Brandão et al. (2008) Biology The eggs are laid in masses; the larvae are rather short, of almost equal thickness throughout, and possessing branched spines on each segment, young larvae group together on a protecting mass of silk; the pupa is slender, with a long abdomen, rather wide and angulated about the insertion of the wings, and suspended by the tail only.

Acraea Doubledayi
''Acraea doubledayi'' is a butterfly in the family Nymphalidae. It is found in Sudan, Uganda, Ethiopia, Somalia, Saudi Arabia and Yemen. Description left, 200px, Figures 1 and 2 ''A. doubledayi'' Guer. (= ''gaekwari'' E. Sharpe) (55 e) may be easily known by the shape of the marginal band of the hindwing, the red-brown ground-colour of the upper surface and the strongly developed black markings, as well as by the small light or transparent spots in 4 to 6 of the fore wing behind the discal dots; under surface of the hindwing reddish yellow with large whitish marginal spots. In the type-form the forewing above has a broad black marginal band, which is formed by the union of the black submarginal streaks with the veins and the marginal line, reaches the light subapical band and encloses yellow marginal spots; both wings above darkened at the base.

Malawi
Malawi (; or aláwi Tumbuka: ''Malaŵi''), officially the Republic of Malawi, is a landlocked country in Southeastern Africa that was formerly known as Nyasaland. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south and southwest. Malawi spans over and has an estimated population of 19,431,566 (as of January 2021). Malawi's capital (and largest city) is Lilongwe. Its second-largest is Blantyre, its third-largest is Mzuzu and its fourth-largest is its former capital, Zomba. The name ''Malawi'' comes from the Maravi, an old name for the Chewa people who inhabit the area. The country is nicknamed "The Warm Heart of Africa" because of the friendliness of its people. The part of Africa now known as Malawi was settled around the 10th century by migrating Bantu groups . Centuries later, in 1891, the area was colonised by the British and became a protectorate of the United Kingdom known as Nyasaland. In 1953, it b ...

Frank Oates
Francis (Frank) Oates (1840–1875) was a British naturalist, explorer, and uncle of Antarctic explorer Lawrence Oates. He was one of the first Europeans to see the Victoria Falls. Early life The second son of Edward Oates (1792–1865), of Meanwoodside, near Leeds, Yorkshire and Furnival's Inn, and his wife Susan (d. 1889), daughter of Edward Grace, J.P., Frank Oates was born at Meanwoodside in 1840. The Oates family were landed gentry, owning land around Leeds and Dewsbury since the 16th century.Burke's Landed Gentry, 17th edition, ed. L. G. Pine, p. 1914, Oates formerly of Gestingthorpe Hall pedigree He was educated at Christ Church, Oxford, which he entered late in 1860, but left before taking a degree. This was due to severe ill health, and he was an invalid for some years after 1864. Oates' first significant expedition was to Central America and North America, and lasted one year, from 1871–1872. Most of this time was spent collecting bird and insect specimens in Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label= Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transvaal Province
The Province of the Transvaal ( af, Provinsie van Transvaal), commonly referred to as the Transvaal (; ), was a province of South Africa from 1910 until 1994, when a new constitution subdivided it following the end of apartheid. The name "Transvaal" refers to the province's geographical location to the north of the Vaal River. Its capital was Pretoria, which was also the country's executive capital. History In 1910, four British colonies united to form the Union of South Africa. The Transvaal Colony, which had been formed out of the bulk of the old South African Republic after the Second Boer War, became the Transvaal Province in the new union. Half a century later, in 1961, the union ceased to be part of the Commonwealth of Nations and became the Republic of South Africa. The PWV (Pretoria-Witwatersrand- Vereeniging) conurbation in the Transvaal, centred on Pretoria and Johannesburg, became South Africa's economic powerhouse, a position it still holds today as Gauteng Pro ...
