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] |
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.

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 vineyards in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Cape
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total. It is roughly the size of England or the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 road (South Africa), N7 national route (South Africa), national route which connects the Cape with Namibia, and at the western end of the N14 road (South Africa), 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 sour ...

Piketberg
Piketberg (also sometimes spelt Piquetberg in the past) is a town in the Western Cape, South Africa, located about 80 km east of Saldanha Bay. The original spelling of the name was "Piquetberg". The town is in the foothills of the Piketberg mountains, a range of low mountains formed from Table Mountain Sandstone. The area around the mountains is conducive to the farming of wheat, while the area on top of the mountains, being cooler and generally frost-free, is suited to the farming of fruit and Rooibos Tea. Piketberg possesses a large Dutch Reformed Church designed by the architect Carl Otto Hager in his trademark neo-Gothic style. History The area was inhabited by the Khoikhoi and the Bushmen, San before the arrival of 21 Dutch, Huguenot and German families in 1705-06, and there is still well-preserved San rock art in the mountains. There was once a small military post in the town to protect the livestock of farmers from raids by the Khoikhoi. By the 1730s the population had ...

Swartberg Pass
The Swartberg Pass on the R328 runs over the Swartberg mountain range (''black mountain'' in English) which runs roughly east–west along the northern edge of the semi-arid area called the Little Karoo in the Western Cape province of South Africa. It's the only road access to Gamkaskloof. History The construction of the Swartberg pass was started under the guidance of Jan Tassies who used 100 workers from Mozambique. After 13 months he went bankrupt and also only completed 6 km of the road! The rest of the pass was built between 1883 and 1888 by Thomas Bain, son of the famous Andrew Geddes Bain who built Bain's Kloof Pass and many more. It followed their earlier construction of another pass in 1858, the Meiringspoort, through the same mountains but further east. It was built using convict labour, and opened on 10 January 1888. The dry-stone retaining walls, supporting some of its hairpin bends, are still in place and over 130 years old. Geography To the north of 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 , 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 ...

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 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 biofuel, ...
