Butterfly
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, it fli ...

Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

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 Sou ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Northern Cape
The Northern Cape is the largest and most sparsely populated province of South Africa. It was created in 1994 when the Cape Province was split up. Its capital is Kimberley. It includes the Kalahari Gemsbok National Park, part of the Kgalagadi Transfrontier Park and an international park shared with Botswana. It also includes the Augrabies Falls and the diamond mining regions in Kimberley and Alexander Bay. The Namaqualand region in the west is famous for its Namaqualand daisies. The southern towns of De Aar and Colesberg found within the Great Karoo are major transport nodes between Johannesburg, Cape Town and Port Elizabeth. Kuruman can be found in the north-east and is known as a mission station. It is also well known for its artesian spring and Eye of Kuruman. The Orange River flows through the province of Northern Cape, forming the borders with the Free State in the southeast and with Namibia to the northwest. The river is also used to irrigate the many vineyar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kamiesberge
The Kamiesberg or Kamiesberge (Khoikhoi ''"Th'amies"'' = ''"jumble"''), is a mountain range of jumbled granite inselbergs or bornhardts dotted over sandy plains and centered on Kamieskroon in Namaqualand in South Africa. This range is very like the Matopos of Zimbabwe in appearance. It stretches for about 140 km (60 mi) from Garies in the south to Springbok in the north and forms a plateau between the Sandveld of the Cape West Coast and Bushmanland in the east, with the Hardveld of the mountainous central Kamiesberg escarpment in the midst. History The region was formerly occupied by Khoikhoi who were nomadic pastoralists. The buildings of Kamieskroon were moved from a previous location known as Bowesdorp, named after the village doctor. Steep granite hills and a shortage of water hindered development, so that it was relocated. The foundations of the original village may still be seen in a rocky ravine some 8 km north of Kamieskroon.

Springbok, Northern Cape
Springbok is the largest town in the Namaqualand area in the Northern Cape province of South Africa. It was called Springbokfontein until 1911, when it was shortened to Springbok. Springbok is located on the N7 national route which connects the Cape with Namibia, and at the western end of the N14, which connects it with Upington and Pretoria. It is the main town of the Nama Khoi Local Municipality, which also includes a number of surrounding towns such as Okiep and Nababeep. The town lies at an elevation of in a narrow valley between the high granite domes of the ''Klein Koperberge'' (Small Copper Mountains). This name gives away the reason for the early settlement which gradually turned into a major commercial and administrative centre for copper mining operations in the region. While the town initially developed rapidly, this slowed when rich copper deposits were discovered in Okiep. As the main source of water, Springbok continued to develop as the commercial and adminis ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 777β200 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 90ΒΊ 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 ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as forage, feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of bi ...

Butterflies Described In 1953
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.

Satyrini
The Satyrini is one of the tribes of the subfamily Satyrinae. It includes about 2200 species and is therefore the largest tribe in the subfamily which comprises 2500 species. Distribution Satyrini butterflies have a worldwide distribution, but the distribution pattern differs between subtribes. Some subtribes are almost restricted to a single biogeographic region, such as the Pronophilina, which is found only in Andean cloud forests from Venezuela to Bolivia. Biology The larval food plants of many species in this tribe are grasses, i.e. Poaceae. It is considered that the Satyrini diversified at about the same time as the grasses did, and that the radiation of the tribe is therefore closely related to the evolution of the grasses. In contrast, the tribe has a few genera which show uncommon feeding preferences. Three genera, ''Euptychia'', ''Ragadia'' and ''Acrophtalmia'', feed on Lycopsida, and moreover, some species of ''Euptychia'' have been reported to feed on mosse ...
