Thestor Calviniae
''Thestor calviniae'', the Hantamsberg skolly, is a butterfly of the family Lycaenidae. It is found in South Africa, where it is only known from montane fynbos in the foothills and at the summit of the Hantamsberg near Calvinia. The 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 ... is 30–34 mm for males and 38–42 mm for females. Peaks in flight times occur in December at lower altitudes and from March to April on the summit of the Hantamsberg. There is one generation per year.

Norman Denbigh Riley
Norman Denbigh Riley CBE (26 September 1890 London – 26 May 1979) was a British entomologist with a special interest in the Lepidoptera and in particular the Lycaenidae. For many years he was keeper of entomology at the British Museum. His first schooling took place at Dulwich College where his interest in natural history and Lepidoptera became evident. Richard South, the prominent entomologist was the Riley family's neighbour in Balham and encouraged Norman Riley in his hobby. After he finishing school Riley enrolled at the Imperial College in order to take a course in entomology, and managed to find work there as a demonstrator under Ray Lankester, who was then director of the British Museum. At age 21 he was appointed as an assistant in the Entomology Department. With the outbreak of World War I in 1914, Riley joined the Royal Army Service Corps, and saw service in France. At the end of the war he was discharged with the rank of captain and resumed his work at the museum, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), 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 Holometabolism, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycaenidae
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species. The family comprises seven subfamilies, including the blues (Polyommatinae), the coppers (Lycaeninae), the hairstreaks (Theclinae), and the harvesters (Miletinae). Description, food, and life cycle Adults are small, under 5 cm usually, and brightly coloured, sometimes with a metallic gloss. Larvae are often flattened rather than cylindrical, with glands that may produce secretions that attract and subdue ants. Their cuticles tend to be thickened. Some larvae are capable of producing vibrations and low sounds that are transmitted through the substrates they inhabit. They use these sounds to communicate with ants.Pierce, N. E.; Braby, M.

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fynbos
Fynbos (; meaning fine plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Overview and history The word fynbos is often confusingly said to mean "fine bush" in Afrikaans, as "bos" means "bush". Typical fynbos foliage is ericoid rather than fine. The term, in its pre-Afrikaans, Dutch form, ''fynbosch'', was recorded by Nob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calvinia
Calvinia is a regional town in the Northern Cape province of South Africa named after the French people, French religious reformer Jean Calvin. The town falls under the Hantam Local Municipality which forms part of the Namakwa District Municipality. The Calvinia district is part of the Great Karoo region of South Africa. The town is just south of the Hantam mountains on the banks of the Oorlogskloof (meaning "War Ravine") River. Calvinia enjoys 80% starlight and is renowned for its kaleidoscope of spring wildflowers coinciding with the Namaqualand wildflower spectacle. An asteroid (1245 Calvinia) is named after the town. History The earliest known people living in the area were Khoisan people. The first Europeans in the area were farmers who took their livestock to the area in the 1750s. On 19 January 1847, at a meeting on the farm Tygerhoek, a new Dutch Reformed Church congregation was founded for the Hantam region. In 1848 the congregation bought 1,200 hectares of the farm H ...

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 and anima ...
