Acraea Petraea
''Acraea petraea'', the blood acraea or blood-red acraea, is a butterfly of the family Nymphalidae. It is found in coastal forests from KwaZulu-Natal to Mozambique, Kenya and Malawi. The wingspan is for males and for females.''A. petraea'' Bdv. (54 f) recalls ''Acraea atolmis, A. atolmis'', from which it can be at once distinguished by the submarginal dots of the forewing. Wings above bright red to orange-yellow with the black markings strongly developed; discal dots 3 to 6 of the forewing are placed in a line vertically to the costal margin and are often enlarged and joined to the median spot; the hindwing beneath light reddish yellow with red spots between the dots and red spots or streaks before the marginal band; the discal dot in 3 seems to be always absent. The females have a broad white or whitish subapical band on the forewing and the ground-colour is often darker, reddish grey to black-grey, particularly on the forewing. The dry-season form, ''petrina'' Suff., has redd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Baptiste Boisduval
Jean Baptiste Alphonse Déchauffour de Boisduval (24 June 1799 – 30 December 1879) was a French lepidopterist, botanist, and physician. He was one of the most celebrated lepidopterists of France, and was the co-founder of the Société entomologique de France. While best known abroad for his work in entomology, he started his career in botany, collecting a great number of French plant specimens and writing broadly on the topic throughout his career, including the textbook ''Flores française'' in 1828. Early in his career, he was interested in Coleoptera and allied himself with both Jean Théodore Lacordaire and Pierre André Latreille. He was the curator of the Pierre Françoise Marie Auguste Dejean collection in Paris and described many species of beetles, as well as butterflies and moths, resulting from the voyages of the ''Astrolabe'', the expedition ship of Jean-François de Galaup, comte de La Pérouse and the '' Coquille'', that of Louis Isidore Duperrey. He left Paris ... [...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 ...

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.

Acraea Cepheus
''Acraea cepheus'', the Cepheus acraea, is a butterfly of the family Nymphalidae. It is found in Africa, from Nigeria and Angola to Uganda, western Tanzania and Zambia. Description ''A. cepheus'' L. (54 f) differs from all the African Acraeids known to me in the hindwing having a submarginal dot in cellule 7, so that there are 3 black dots in this cellule ; the forewing has a black transverse streak at the middle and one at the apex of the cell and large discal dots, of which the one in 1 b is nearer to the distal margin than that in 2 and those in cellules 3 to 6 form a transverse band, at least in the male the submarginal dots are often united with the black marginal band. The marginal band of the hindwing is 2 mm. in breadth, proximally dentate on the veins, above unicolorous, beneath spotted with light yellow, and the discal dots are approximated to the base; beneath the ground-colour is light yellowish to whitish, with large red or orange-yellow spots between the black ...

Xylotheca Kraussiana
''Xylotheca kraussiana'' is an African shrub or small multi-stemmed tree growing in the sandveld and widely distributed throughout the eastern parts of Southern Africa, in particular the eastern Transvaal, coastal Natal and Mozambique, preferring the sandy soils of coastal bush and forest. 'Xylotheca' meaning 'woody case' and the species name honouring Dr C.F.F. Krauss (1812-1890), a German naturalist, who later became director of Stuttgart's Natural History Museum. Krauss came to the Cape in 1838, collected in Natal from 1839 to 1840. About 8 other species of ''Xylotheca'' are to be found in central Africa and Madagascar. Leaves are dull grey-green, alternate and covered in soft grey hairs. Flowers are white with a dense central cluster of yellow anthers and resembling a small white rose. The fruit is an ovoid woody capsule about long and distinctly ridged. Yellow when ripe, it partly splits into 5 sections revealing black seeds with a bright red aril. The pulp around the seeds ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

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 . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Malawi
Malawi (; or aláwi Tumbuka: ''Malaŵi''), officially the Republic of Malawi, is a landlocked country in Southeastern Africa that was formerly known as Nyasaland. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south and southwest. Malawi spans over and has an estimated population of 19,431,566 (as of January 2021). Malawi's capital (and largest city) is Lilongwe. Its second-largest is Blantyre, its third-largest is Mzuzu and its fourth-largest is its former capital, Zomba. The name ''Malawi'' comes from the Maravi, an old name for the Chewa people who inhabit the area. The country is nicknamed "The Warm Heart of Africa" because of the friendliness of its people. The part of Africa now known as Malawi was settled around the 10th century by migrating Bantu groups . Centuries later, in 1891, the area was colonised by the British and became a protectorate of the United Kingdom known as Nyasaland. In 1953, it became ...
