Bematistes Vestalis
''Bematistes vestalis'', the smoky bematistes, is a butterfly in the family Nymphalidae. It is found in Senegal, Guinea, Burkina Faso, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Democratic Republic of the Congo and Tanzania. Description . ''P. vestalis'' is distinguished from all the other species by the transverse band on the upperside of the forewing, otherwise so sharply conspicuous, being entirely absent or only in its posterior part (in cellules l-2) distinct and light grey-yellow; cellule 1 a is nearly always yellowish to beyond the middle; the hindwing above is light brown-yellow at least to the middle, but beneath only yellow-brown at the base as far as the apex of the cell. In the type-form ''vestalis'' Fldr. (58 e) the upperside of the fore wing is unicolorous blackish to the base except for a yellow stripe at the hindmargin and the more or less distinct transverse band and the hindwing above has a bla ...

Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita ( ...

Butterflies Of Africa
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 ...

Acraeini
The Acraeini are a tribe of butterflies of the subfamily Heliconiinae in the family Nymphalidae. Genera The recognized genera are: Tree of Life * '' Abananote'' Potts, 1943 * ''Acraea'' Fabricius, 1807 – acraeas * '' Actinote'' Hübner, 819/small> – actinotes * '' Altinote'' Potts, 1943 – altinotes * '' Bematistes'' Hemming, 1935 *'' Cethosia'' (Fabricius, 1807) – lacewings * '' Miyana'' (Fruhstorfer, 1914) The genus ''Acraea'' is highly paraphyletic In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be pa ... and needs to be redelimited. This will possibly re-establish the old genus ''Telchinia'', and perhaps others. The genus '' Pardopsis'' Trimen, 1887, previously included in Acraeini, has tentatively been moved to the Argynnini tribe. References External links ...

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 ...

Adenia Cisampelloides
''Adenia'' is a genus of flowering plants in the passionflower family, Passifloraceae. It is distributed in the Old World tropics and subtropics.''Adenia''. Flora of China. The center of diversity, centers of diversity are in Madagascar, eastern and western tropical Africa, and Southeast Asia. The genus name ''Adenia'' comes from "aden", reported as the Arabic name for the plant by Peter Forsskål, the author of the genus. Description All ''Adenia'' are perennial plants, but there are many different forms, including herbs, vines, lianas, shrubs, and trees. Many are succulent plant, succulents and some are pachycauls.

Pseudacraea Eurytus
''Pseudacraea eurytus'', the false wanderer, is a butterfly of the family Nymphalidae. It is found in Africa. Description The numerous forms of this group dolomena'' and ''Pseudacraea rubrobasalis">rubrobasalis''may be known at once by the long, distinct black streaks on the interneural folds of the hindwing; forewing always with 5 rounded black spots in the cell and 1 or 2 at the base of cellule 1b. The butterflies stand in interesting but very complicated mimetic relations with the ''Planema'' species which fly together with them. In the males the forewing is more pointed with the distal margin straight or slightly in the females the forewing very obtusely rounded with the distal margin curved. * ''Ps. eurytus'' L. (46 c). The hindmarginal spot of the forewing is large, reaches vein 3 and has its proximal edge sharp and straight, but does not cover the base of cellules 1b and 2; hindwing beneath at the base reddish, in the male above red-yellow, towards the distal margin gr ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
