Alenia Namaqua
''Alenia namaqua'', the Namaqua dancer or Namaqua sandman, is a butterfly of the family Hesperiidae. It is only known from Namaqualand in the Northern Cape of South Africa, from Calvinia north through Kamiensberg into Namibia. 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 21–26 mm for males and 26–29 mm for females. Adults are on wing from September to November. There is one generation per year. The larvae feed on '' Blepharis capensis''. References Butterflies described in 1974 Carcharodini {{Pyrginae-stub ...

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 ...

Hesperiidae
Skippers are a family of the Lepidoptera (moths and butterflies) named the Hesperiidae. Being diurnal, they are generally called butterflies. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea, the butterflies. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly have an absence of wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea. The ...

Namaqualand
Namaqualand (khoekhoe: "Nama-kwa" meaning Nama Khoe people's land) is an arid region of Namibia and South Africa, extending along the west coast over and covering a total area of . It is divided by the lower course of the Orange River into two portions – Little Namaqualand to the south and Great Namaqualand to the north. Little Namaqualand is within the Namakwa District Municipality, forming part of Northern Cape Province, South Africa. It is geographically the largest district in the country, spanning over 26,836 km2. A typical municipality is Kamiesberg Local Municipality. The semidesert Succulent Karoo region experiences hot summers, sparse rainfall, and cold winters.Discover South Africa: Your Online Travel Directory. Discover Namakwa.

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 ...

Blepharis Capensis
''Blepharis'' is a genus of plant in family Acanthaceae. It contains around 126 species found in seasonally dry to arid habitats from Africa over Arabia to Southeast Asia. In section ''Acanthodium'', there are 13–15 species that use the carbon fixation pathway. Phylogenetic analysis suggests that this pathway evolved up to three times independently in the genus over the last five million years.
