Acraea Insularis
''Acraea insularis'' is a butterfly in the family Nymphalidae. It is found on the island of São Tomé. The species was first named in 1893 by Emily Mary Bowdler Sharpe. Description ''A. insularis'' E. Sharpe. Forewing above black-brown with a yellow transverse spot in the middle of the cell and a similar orange-yellow spot at its apex, an orange-yellow spot in the basal part of 2, a free, crescentic, small spot in 1 b near the distal margin and three small orange-yellow subapical spots in 4-6, of which the one in 4 is placed nearer to the distal margin and quite free. The hind wing above at the base blackish as far as vein 2, then with a broad median band about 5 mm. in breadth, at the inner margin and towards the base light yellow, distally orange-yellow, projecting almost rectangularly distad in cellule 4 (almost as in '' johnstoni'') and adorned with black discal dots; the hindwing beneath light yellowish to the base with free black dots and beyond the middle with a broad b ...

Emily Mary Bowdler Sharpe
Emily Mary Bowdler Sharpe, born on 11 December 1868, was an English entomologist, colourist and illustrator Emily Mary Bowdler Sharpe was the eldest of ten daughters of Richard Bowdler Sharpe (1847–1909) and Emily Eliza Sharpe (née Burrows; 1842–1928). She had 11 sisters and one brother who died in infancy. She learned her craft from her father and initially she worked as a colourist on her father's books before dedicating herself to the study of butterflies. She worked throughout her life on butterflies, and described many new species.

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] |
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.

São Tomé Island
São Tomé Island, at , is the largest island of São Tomé and Príncipe and is home in May 2018 to about 193,380 or 96% of the nation's population. The island is divided into six districts. It is located 2 km (1¼ miles) north of the equator. Geography São Tomé Island is about long (north-south) by wide (east-west). It rises to at Pico de São Tomé and includes the capital city, São Tomé, on the northeast coast. The nearest city on mainland Africa is the port city of Port Gentil in Gabon located to the east. The island is surrounded by a number of small islands, including Ilhéu das Rolas, Ilhéu das Cabras and Ilhéu Gabado. Languages The main language is Portuguese, but there are many speakers of Forro and Angolar (Ngola), two Portuguese-based creole languages. The name "Sao Tome" is Portuguese for "Saint Thomas." Geology The entire island of São Tomé is a massive shield volcano that rises from the floor of the Atlantic Ocean, over below sea lev ...

Acraea Johnstoni
''Acraea johnstoni'', or Johnston's acraea, is a butterfly in the family Nymphalidae that is native to East Africa. Range It is found in southern Sudan, northern Uganda, Ethiopia, Kenya, Tanzania, Malawi, Zambia, western Mozambique and eastern Zimbabwe. Description ''A. johnstoni'', only differs from '' lycoa'' in not having the basal area of the hindwing uniformly rounded distally, but more or less projecting or angled in cellule 4; this character is especially pronounced on the under surface. The species is no less variable than ''lycoa''; the light spots of the fore wing are light yellow or white and the spot in 1b is placed quite free; the forms are connected by intermediates. Palpus yellowish. * ''johnstoni'' Godm. (57 d). The black ground-colour of the forewing above is restricted to the base and the distal margin, being covered in the middle by a very broad orange-yellow band, irregularly defined distally, which reaches the light yellow spots, but extends scarcely or no ...

Acraea Jodutta
''Acraea jodutta'', the jodutta acraea, is a butterfly in the family Nymphalidae. It is found in Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Equatorial Guinea, São Tomé and Príncipe, Gabon, the Republic of the Congo, the Central African Republic, Angola, the Democratic Republic of the Congo, Sudan, Uganda, Kenya and Ethiopia. Description ''A. jodutta'' F. (57 e). Wings above black-brown; the forewing as in esebria with a light subapical band, which is always broad and has a spot in 3, and a sharply defined hindmarginal spot about 6 mm. in breadth, reaching vein 3 but leaving the base of cellules 1 a and 1 b free; the hindmarginal spot is continued on the hindwing as a median band of equal breadth or somewhat widened; the light markings are dull light-yellow in the male, pure white in the female. Senegal to the Cameroons. ab. ''carmentis'' Dbl. and Hew. (57 e) only differs from the female of the type-form in the subapical band of the fore wing ...

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. '' A. horta'', '' A. cabira'', and '' A. terpsicore'' illustrate typical life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, f ...

Endemic Fauna Of São Tomé Island
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
