Mylothris Rueppellii
''Mylothris rueppellii'', the Rüppell's dotted border or twin dotted border, is a butterfly of the family Pieridae. It is found in most of Africa, south of the Sahara. The wingspan is for males and for females. Adults are on wing year-round, with peaks in October and from late February to April in southern Africa. The larvae feed on various Loranthaceae species, including ''Loranthus'', ''Tapinanthus oleifolius'' and ''Tapinanthus rubromarginatus''. It is named after the German naturalist Eduard Rüppell, who had travelled in Africa in 1830. Description the upperside of the wings exhibits a striking characteristic where deep orange basal scaling covers, about half of the forewing cell. The underside of the wings features lighter shades of white or cream, accompanied by faint markings and patterns. Habitat ''Mylothris rueppellii'' is typically found in habitats characterized by forests and densely wooded savannas. Both sexes prefer to fly high at the tree tops. Distributio ...

Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large 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 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, and after its wings have expanded and dried, it fli ...

Pieridae
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia.DeVries P. J. in Levin S.A. (ed) 2001 The Encyclopaedia of Biodiversity. Academic Press. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family.Carter, David (2000). ''Butterflies and Moths''. The family was created by William John Swainson in 1820. The name "butterfly" is believed to have originated from a member of this family, the brimstone, ''Gonepteryx rhamni'', which was called the "butter-coloured fly" by early British naturalists. The sexes usually differ, often in the pattern or number of the black markings. The larvae (caterpillars) of a few of these species, such ...

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, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...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 .

Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are '' Nuytsia floribunda'' (the Western Australian Christmas tree), '' Atkinsonia ligustrina'' (from the Blue Mountains of Australia), and ''Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while ''Tristerix aphyllus'' is almost holoparasitic. For a more complete description of the Australian Loranthaceae, seFlora of Australia online, for the Malesian Loranthaceae seFlora of Malesia Originally, Loranthaceae contained all mistletoe species, but the mistletoes of Europe and North America ('' Viscum'', ''Arceuthobium'', and '' Phoradendron'') belong to the family Santalaceae. The APG II system 2003 assigns the family to the order Santalales in the clade core eudicots. P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loranthus
''Loranthus'' is a genus of parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers. Other treatments restrict the genus to a few species. The systematic situation of ''Loranthus'' is not entirely clear. The generic name in botanical Latin means strap-flower, in reference to the shape of the petals. Taxonomy The taxonomic history of the generic name ''Loranthus'' is complicated. In 1753, Carl Linnaeus used the name ''Loranthus'' for a genus of one species, ''Loranthus americanus'', which was thus the type species. He later added other species, including ''Loranthus scurrula'' in 1762, a species he had previously placed in a separate genus, ''Scurrula'', and ''Loranthus europaeus'' in 1763, a name first used by Jacquin in 1762. However, ''Loranthus americanus'' has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eduard Rüppell
Wilhelm Peter Eduard Simon Rüppell (20 November 1794 – 10 December 1884) was a German naturalist and explorer. Rüppell is occasionally transliterated to "Rueppell" for the English alphabet, due to german orthography. Biography Rüppell was born in Frankfurt am Main, the son of a prosperous banker, who was a partner in 'Rüppell und Harnier’s Bank'. He was originally destined to be a merchant, but after a visit to Sinai in 1817, where he met Henry Salt and the Swiss-German traveller Ludwig Burckhardt. He explored Giza and the Pyramids with Salt. In 1818, he developed an interest in natural history, and became elected member of the ''Senckenbergische Naturforschende Gesellschaf''. He attended lectures at the University of Pavia and University of Genoa in botany and zoology. Rüppell set off on his first expedition in 1821, accompanied by surgeon Michael Hey as his assistant. They travelled through the Sinai desert, and in 1822 were the first European explorers to reach the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
