Hypolycaena Buxtoni
''Hypolycaena buxtoni'', the Buxton's hairstreak, is a butterfly of the family Lycaenidae. It is found in southern Africa. The wingspan is 25–30 mm for males and 28–33 mm for females. Adults are on wing from September to May (with a peak in October and November) and from February to May (with a peak in March and April). There are two generations per year. The larvae feed on ''Tricalysia'' and ''Pavetta ''Pavetta'' is a genus of flowering plants in the family Rubiaceae. It comprises about 360 species of trees, evergreen shrubs and sub-shrubs.

William Chapman Hewitson
William Chapman Hewitson (9 January 1806, in Newcastle upon Tyne – 28 May 1878, in Oatlands Park, Surrey) was a British naturalist. A wealthy collector, Hewitson was particularly devoted to Coleoptera (beetles) and Lepidoptera (butterflies and moths) and, also, to birds' nests and eggs. His collection of butterflies, collected by him as well as purchased from travellers throughout the world, was one of the largest and most important of his time. He contributed to and published many works on entomology and ornithology and was an accomplished scientific illustrator. Life William Hewitson was educated in York. He became a land-surveyor and was for some time employed under George Stephenson on the London and Birmingham Railway. Delicate health and the accession to an ample fortune through the death of a relative led him to give up his profession and he afterwards devoted himself to scientific studies. He lived for a time at Bristol and Hampstead. In 1848 he purchased ten or tw ... [...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] |
Lycaenidae
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species. The family comprises seven subfamilies, including the blues (Polyommatinae), the coppers (Lycaeninae), the hairstreaks (Theclinae), and the harvesters (Miletinae). Description, food, and life cycle Adults are small, under 5 cm usually, and brightly coloured, sometimes with a metallic gloss. Larvae are often flattened rather than cylindrical, with glands that may produce secretions that attract and subdue ants. Their cuticles tend to be thickened. Some larvae are capable of producing vibrations and low sounds that are transmitted through the substrates they inhabit. They use these sounds to communicate with ants.Pierce, N. E.; Braby, M. F.; Heath, A.; Lohman, D. J.; Mathew, J.; Rand, D. B. & Travassos, M. A. (2002)"The eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...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 ...

Pavetta
''Pavetta'' is a genus of flowering plants in the family Rubiaceae. It comprises about 360 species of trees, evergreen shrubs and sub-shrubs. It is found in woodlands, grasslands and thickets in sub-tropical and tropical Africa and Asia. The plants are cultivated for their simple but variable leaves, usually opposite but also occur in triple whorls. The leaves are often membranous with dark bacterial nodules. ''Pavetta'' has small, white, tubular flowers, sometimes salviform or funnel-shaped with 4 spreading petal lobes. The flowers are carried on terminal corymbs or cymes.Encyclopaedia of Garden Plants, C. Brickell, 1996, London, Royal Horticultural Society, .
