Kedestes Lenis
''Kedestes lenis'', the unique ranger, is a butterfly of the family Hesperiidae. It is found in South Africa. The wingspan is 26–31 mm for males and 29–35 mm for females. Adults are on wing from October to March (with a peak in spring for subspecies ''K. l. lenis'' and in midsummer for subspecies ''K. l. alba''). There is one generation per year. The larvae feed on ''Imperata cylindrica'' and ''Imperata arundinacea ''Imperata cylindrica'' (commonly known as cogongrass or kunai grass ) is a species of perennial rhizomatous grass native to tropical and subtropical Asia, Micronesia, Melanesia, Australia, Africa, and southern Europe.

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] |
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.

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] |
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 ...

Imperata Cylindrica
''Imperata cylindrica'' (commonly known as cogongrass or kunai grass ) is a species of Perennial plant, perennial rhizomatous grass native to tropical and subtropical Asia, Micronesia, Melanesia, Australia, Africa, and southern Europe. It has also been introduced to Latin America, the Caribbean, and the southeastern United States. It is a highly flammable pyrophyte, and can spread rapidly by colonizing disturbed areas and encouraging more frequent wildfires. Common names The species is most commonly known in English as "cogongrass", from Castilian Spanish, Spanish ''cogón'', from the Tagalog language, Tagalog and Visayan languages, Visayan ''kugon''. Other common names in English include ''kunai grass'', ''blady grass'', ''satintail'', ''spear grass'', ''sword grass'', ''thatch grass'', ''alang-alang'', ''lalang grass'', ''cotton wool grass'', and ''kura-kura'' , among other names.

Kedestes
''Kedestes'' is a genus of skippers in the family Hesperiidae, commonly known as rangers. The genus is restricted to the Afrotropical realm, where it occurs mostly in the East and South.
