Thestor Brachycerus
''Thestor brachycerus'', the Knysna skolly, is a species of butterfly in the family Lycaenidae. It is endemic to South Africa. The wingspan is 27–36 mm for males and 29–39 mm for females. Adults are on the wing from December to January. There is one generation per year. Larvae have been found in the nests of the pugnacious ant, ''Anoplolepis custodiens'', but the larval food is unknown.

Roland Trimen
Roland Trimen Fellow of the Royal Society, FRS (29 October 1840 in London – 25 July 1916 in London) was a British-South African Natural history, naturalist, best known for ''South African Butterflies'' (1887–89), a collaborative work with Colonel James Henry Bowker. He was among the first entomologists to investigate mimicry and Polymorphism (biology), polymorphism in butterflies and their restriction to females. He also collaborated with Charles Darwin to study the pollination of ''Disa (plant), Disa'' orchids. Life and career Trimen was born in London in 1840, the son of Richard and Mary Ann Esther Trimen and the older brother of the botanist Henry Trimen (1843-1896) who went to Ceylon (now Sri Lanka). He went to study at Rottingdean and then at King's College School in Wimbledon. Trimen was interested in entomology but a chronic Larynx, laryngeal condition forced him to move to the Cape of Good Hope as a treatment. Reaching there he volunteered under Edgar Leopold ...

Montagu, Western Cape
Montagu is a town in the Western Cape province of South Africa, about from Cape Town in the Western Little Karoo. The town is named after former secretary of the Cape Colony, John Montagu (colonial secretary), John Montagu, but was once known as Agter Cogman's Kloof, Cogman's Kloof linking the town and railway station. It is situated at the confluence of the Keisie and Kingna rivers. Montagu was founded on the farm "Uitvlugt" in 1851, and is known for its hot mineral springs and scenic mountains. It is also an agricultural centre, where orchards and vineyards are in production and local herbs are grown. The farming area, 'Koo', lies north of the town and is famous for the quality of its apples, pears, apricots and peaches. Recreation Nearby rock formations make it one of the country's major rock climbing venues. The high Bloupunt peak overlooks the village and offers several hiking trails, as well as kloofing and mountain biking trails further afield. Popular crags for ro ...

Endemic Butterflies Of South Africa
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Butterflies Described In 1883
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous 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, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take several ye ...

Stanford, Western Cape
Stanford is a small riverside village in Overberg District Municipality in the Western Cape province of South Africa. Located 16 km east of Hermanus and 22 km north-east of Gansbaai. History The village of Stanford was founded in 1857 and named after its founder, Sir Robert Stanford, who owned the original farm and had a number of business interests in the area. Stanford, also a captain in the British army, was effectively exiled from the Cape after being ordered to supply the convict carrying ship, The Neptune, with provisions during the Convict crisis of 1849. Situated in the heart of the Overberg, Stanford is known for its beautifully preserved and renovated Cape Victorian and Edwardian styled houses and buildings. The village as a whole was declared a Heritage Site and in 1992 the Stanford Conservation Trust was formed to ensure the protection and conservation of the environment and heritage resources in and around Stanford. The work of the Trust ensured that Stanfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kogelberg
The Kogelberg is a range of mountains along the False Bay coast in the Western Cape of South Africa. They form part of the Cape Fold Belt, starting south of the Elgin valley and forming a steep coastal range as far as Kleinmond. The Kogelberg area has the steepest and highest drop directly into the ocean of any southern African coastal stretch. Ecology The mountains are made predominantly of Table Mountain Sandstone and form some very rugged terrain, which is extremely rich in fynbos, the native Cape flora. The Elgin Valley's surrounding mountain ranges are considered the hub of the Cape floral kingdom. They contain more plant species than anywhere else in the floral region, and a large section of the mountain range is now protected in the massive Kogelberg Nature Reserve. The unique local vegetation type is classified as Kogelberg Sandstone Fynbos. The climate is Mediterranean The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded ...

Outeniqua Mountains
The Outeniqua Mountains, named after the Outeniqua Khoikhoi who lived there, is a mountain range that runs a parallel to the southern coast of South Africa, and forms a continuous range with the Langeberg to the west and the Tsitsikamma Mountains to the east. It was known as ''Serra de Estrella'' (Mountain of the Star) to the Portuguese. The mountains are part of the Garden Route of South Africa. Nomenclature "Outeniqua" is said to be derived from a Khoikhoi tribe that once lived in the mountains, and means "they who bear honey". Indigenous rock paintings can still be found in the area. History The San and Khoi people inhabited the mountains before the arrival of Europeans in the 1600s. The rugged mountains have long posed a barrier to the Klein Karoo and early settlers in the late 1600s used to follow herds of elephants to find easier ways through the area. The region was first explored by white settlers in 1668. In 1782 French explorer ornithologist François Levaillant e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swartberg
The Swartberg mountains (''black mountain'' in English language, English) are a mountain range in the Western Cape province of South Africa. It is composed of two main mountain chains running roughly east–west along the northern edge of the semi-arid Little Karoo. To the north of the range lies the other large semi-arid area in South Africa, the Great Karoo. Most of the Swartberg Mountains are above 2000 m high, making them the tallest mountains in the Western Cape. It is also one of the longest, spanning some 230 km from south of Laingsburg, Western Cape, Laingsburg in the west to between Willowmore and Uniondale, Western Cape, Uniondale in the east. Geologically, these mountains are part of the Cape Fold Belt. Much of the Swartberg is part of a UNESCO World Heritage Site. The two ranges The Swartberg consists of two officially named ranges, the Smaller and the Greater Swartberg Mountains. ''Klein Swartberge'' The Smaller Swartberg are the westernmost of the two.

Langeberg
The Langeberg Range is a mountain range in the Western Cape province of South Africa. Its highest peak is Keeromsberg at 2,072 m that lies 15 km northeast of the town of Worcester. Some of the highest peaks of the range are located just to the north of Swellendam, in a subrange known as the Clock Peaks whose highest point is the 1,710 m high Misty Point. Local lore states one can tell the time by means of the shadows cast by the seven summits of the Clock Peaks. Etymology The name is Dutch and means "long mountain" Physiography and geology The range runs roughly NW/SE in its western part and in an east-west direction in its mid and eastern section and is approximately 250 km long, from Worcester, past Robertson, Montagu, Swellendam, Heidelberg and Riversdale to the proximity of George. The Langeberg's most westerly point is located 5 km east of the town of Worcester; the range ends some 20 km North of Mossel Bay in the east. The open plains of the ...
