Acraea Hypoleuca
''Acraea hypoleuca'', the Namibian acraea, is a butterfly in the family Nymphalidae. It is found in Namibia. Description ''A. hypoleuca'' Trim. Expanse about 60 mm. Wings above orange-red; forewing above with dark marginal band, which encloses 8 large light marginal spots; discal dots in 1 b to 6, all rounded, that in 1 b near the distal margin, those in 2 to 4 in a line, those in 4 to 6 also in a line, placed almost vertically to the preceding; beneath as above, but with whitish subapical band. Hindwing above with white-spotted marginal band 2 mm. in breadth and distinct discal spots, beneath marked as above but with whitish ground colour and larger white marginal spots. Seems to be nearly allied to '' A. chilo'' and ''Acraea zetes''. The only known specimen probably came from German South-West Africa. Biology The habitat consists of gullies and granite outcrops. Adults have been recorded feeding on the flowers of '' Psilocaulon'' species and '' Calicorema capitata''. They ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland Trimen
Roland Trimen Fellow of the Royal Society, FRS (29 October 1840 in London – 25 July 1916 in London) was a British-South African Natural history, naturalist, best known for ''South African Butterflies'' (1887–89), a collaborative work with Colonel James Henry Bowker. He was among the first entomologists to investigate mimicry and Polymorphism (biology), polymorphism in butterflies and their restriction to females. He also collaborated with Charles Darwin to study the pollination of ''Disa (plant), Disa'' orchids. Life and career Trimen was born in London in 1840, the son of Richard and Mary Ann Esther Trimen and the older brother of the botanist Henry Trimen (1843-1896) who went to Ceylon (now Sri Lanka). He went to study at Rottingdean and then at King's College School in Wimbledon. Trimen was interested in entomology but a chronic Larynx, laryngeal condition forced him to move to the Cape of Good Hope as a treatment. Reaching there he volunteered under Edgar Leopold ...

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.

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acraea Chilo
''Acraea chilo'' is a butterfly in the family Nymphalidae. It is found in Sudan, Ethiopia, Kenya, Tanzania, Somalia, Saudi Arabia and Yemen. Description ''A. chilo'' Godm. (55 a; and 54 c, as ''barberi''). The basal dot in 1 c and the discal dots in 2 to 4 of the forewing all four stand in a line running almost parallel with the costal margin. In this ''chilo'' and the following species elateddiffer from all the rest of the subgroup. Such an arrangement of these dots is also very rare among the other African Acraeids, only occurring in ''niobe, hypoleuca, anacreon, mirifica'' and approximately also in ''wigginsi'' and ''neobule''. male: forewing above light yellowish red, somewhat rose-coloured, at the base not or little darkened; forewing with the marginal band spotted with orange-yellow, 3 to 6 mm. broad, of uniform breadth or widened at the apex, a basal dot in 1 b, 2 in the cell, a median spot and large discal dots in 1 b to 6, of which the dot in lb is placed much nearer to ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

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 ...
