Acraea Medea
''Acraea medea'' is a butterfly in the family Nymphalidae. It is found on the island of Príncipe. It is also considered a subspecies of ''Acraea egina'', ''Acraea egina medea''. Description ''A. medea'' Cr. (54 d) is in my urivilliusopinion best treated as an independent species. The light yellow marginal spots on the underside of the forewing and the thick black submarginal line which bounds them proximally form quite a new feature, to which nothing in '' egina'' and its races corresponds. Both wings above at the base broadly black to vein 2 or 3, then as far as the sharply defined black marginal band, which is 4 to 5 mm. in breadth, yellow-red (male) or white (female) with very large discal dots, arranged quite as in egina; fore wing beneath reddish, at the base and in the female also in the middle light yellow or whitish; hindwing beneath in the middle greenish light yellow or whitish, at the base and at the marginal band with brown-red or orange-yellow spots.

Catonephele Acontius
''Catonephele acontius'', the Acontius firewing, is a nymphalid butterfly species found in South America. It was first described by Carl Linnaeus in 1771 (who gave the type location as "China", a designation followed by some later authors). Description (Male, described by Dru Drury): Upperside. Antennae, head, thorax, and abdomen The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the tors ... black. Wings fine velvety black. An orange-coloured bar, about inch (6 mm) broad, rises in the middle of the superior wings, running circularly and crossing the inferior ones, meeting about the middle of the abdominal edges. Underside. Palpi white. Tongue brown. Breast and legs white. Abdomen yellow brown. Wings shining brown, exhibiting various shades of changeable colours; the tips terminating ...

Pieter Cramer
Pieter Cramer (21 May 1721 (baptized) – 28 September 1776), was a wealthy Dutch merchant in linen and Spanish wool, remembered as an entomologist. Cramer was the director of the Zealand Society, a scientific society located in Flushing, and a member of ''Concordia et Libertate'', based in Amsterdam. This literary and patriotic society, where Cramer gave lectures on minerals, commissioned and/or financed the publishing of his book ''De uitlandsche Kapellen'', on foreign (exotic) butterflies, occurring in three parts of the world Asia, Africa and America. Cramer assembled an extensive natural history collection that included seashells, petrifications, fossils and insects of all orders. Many were colourful butterflies and moths ( Lepidoptera), collected in countries where the Dutch had colonial or trading links, such as Surinam, Ceylon, Sierra Leone and the Dutch East Indies. Cramer decided to get a permanent record of his collection and so engaged the painter Gerrit Wartenaar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acraea Egina
''Acraea egina'', the elegant acraea, is a species of butterfly in the family Nymphalidae with an extensive range in sub-Saharan Africa. Distribution This species can be found in Senegal, Gambia, Guinea-Bissau, Guinea, Burkina Faso, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Equatorial Guinea, Gabon, the Republic of the Congo, the Central African Republic, Angola, the Democratic Republic of the Congo, Sudan, Uganda, Ethiopia, Kenya, Tanzania, Malawi, Zambia, Mozambique, Zimbabwe and South Africa.

Acraea (butterfly)
''Acraea'' is a genus of brush-footed butterflies (family Nymphalidae) of the subfamily Heliconiinae. It seems to be highly paraphyletic and has long been used as a "wastebin taxon" to unite about 220 species of anatomically conservative Acraeini. Some phylogenetic studies show that the genus ''Acraea'' is monophyletic if '' Bematistes'' and Neotropical '' Actinote'' are included (see Pierre & Bernaud, 2009). Most species assembled here are restricted to the Afrotropical realm, but some are found in India, Southeast Asia, and Australia.Silva-Brandão et al. (2008) Biology The eggs are laid in masses; the larvae are rather short, of almost equal thickness throughout, and possessing branched spines on each segment, young larvae group together on a protecting mass of silk; the pupa is slender, with a long abdomen, rather wide and angulated about the insertion of the wings, and suspended by the tail only.

Consortium For The Barcode Of Life
The Consortium for the Barcode of Life (CBOL) was an international initiative dedicated to supporting the development of DNA barcoding as a global standard for species identification. CBOL's Secretariat Office is hosted by the National Museum of Natural History, Smithsonian Institution, in Washington, DC. Barcoding was proposed in 2003 by Prof. Paul Hebert of the University of Guelph in Ontario as a way of distinguishing and identifying species with a short standardized gene sequence. Hebert proposed the 658 bases of the Folmer region of the mitochondrial gene cytochrome-C oxidase-1 as the standard barcode region. Hebert is the Director of the Biodiversity Institute of Ontario, the Canadian Centre for DNA Barcoding, and the International Barcode of Life Project (iBOL), all headquartered at the University of Guelph. The Barcode of Life Data Systems (BOLD) is also located at the University of Guelph. CBOL was created in May 2004 with support of the Alfred P. Sloan Foundation ...

Endemic Fauna Of Príncipe
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
