William Chapman Hewitson
William Chapman Hewitson (9 January 1806, in Newcastle upon Tyne – 28 May 1878, in Oatlands Park, Surrey) was a British naturalist. A wealthy collector, Hewitson was particularly devoted to Coleoptera (beetles) and Lepidoptera (butterflies and moths) and, also, to birds' nests and eggs. His collection of butterflies, collected by him as well as purchased from travellers throughout the world, was one of the largest and most important of his time. He contributed to and published many works on entomology and ornithology and was an accomplished scientific illustrator. Life William Hewitson was educated in York. He became a land-surveyor and was for some time employed under George Stephenson on the London and Birmingham Railway. Delicate health and the accession to an ample fortune through the death of a relative led him to give up his profession and he afterwards devoted himself to scientific studies. He lived for a time at Bristol and Hampstead. In 1848 he purchased ten or tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (season)
Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa. At the spring (or vernal) equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the Summer Solstice in June (Northern Hemisphere) and December (Southern Hemisphere). Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection and regrowth. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, monsoonal or cyclonic. Cultures may have local names for seasons which have little equivalence to the terms originating in Europe. Meteoro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charaxes
The rajah and pasha butterflies, also known as emperors in Africa and Australia, (genus ''Charaxes'') make up the huge type genus of the brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. They belong to the tribe Charaxini, which also includes the nawab butterflies ('' Polyura''). ''Charaxes'' are tropical Old World butterflies, with by far the highest diversity in sub-Saharan Africa, a smaller number from South Asia to Melanesia and Australia, and a single species ('' C. jasius'') in Europe. They are generally strong flyers and very popular among butterfly collectors. Etymology ''Charaxes'' means "to sharpen" or "to make pointed", referring to the pointed 'tails' on the hind wing. ''Charaxes'' may also be related to ''charax'', meaning 'a sharp stake', or ''charaxis'', a 'notch' or 'incision', which are also features of the hind wing. Biology ''Charaxes'' frequent sunny forest openings and glades where they rest with open or partly open wings sunning themsel ...

Butterflies Described In 1877
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 flie ...

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 ...

Royal Museum For Central Africa
The Royal Museum for Central Africa or RMCA ( nl, Koninklijk Museum voor Midden-Afrika or KMMA; french: Musée royal de l'Afrique centrale or MRAC; german: Königliches Museum für Zentralafrika or KMZA), also officially known as the AfricaMuseum, is an ethnography and natural history museum situated in Tervuren in Flemish Brabant, Belgium, just outside Brussels. It was built to showcase King Leopold II's Congo Free State in the International Exposition of 1897. The museum focuses on the Congo, a former Belgian colony. The sphere of interest, however, especially in biological research, extends to the whole Congo River basin, Middle Africa, East Africa, and West Africa, attempting to integrate "Africa" as a whole. Intended originally as a colonial museum, from 1960 onwards it has focused more on ethnography and anthropology. Like most museums, it houses a research department in addition to its public exhibit department. Not all research pertains to Africa (e.g. research on ...

Tamarindus Indica
Tamarind (''Tamarindus indica'') is a leguminous tree bearing edible fruit that is probably indigenous to tropical Africa. The genus ''Tamarindus'' is monotypic, meaning that it contains only this species. It belongs to the family Fabaceae. The tamarind tree produces brown, pod-like fruits that contain a sweet, tangy pulp, which is used in cuisines around the world. The pulp is also used in traditional medicine and as a metal polish. The tree's wood can be used for woodworking and tamarind seed oil can be extracted from the seeds. Tamarind's tender young leaves are used in Indian and Filipino cuisine. Because tamarind has multiple uses, it is cultivated around the world in tropical and subtropical zones. Description The tamarind is a long-lived, medium-growth tree, which attains a maximum crown height of . The crown has an irregular, vase-shaped outline of dense foliage. The tree grows well in full sun. It prefers clay, loam, sandy, and acidic soil types, with a high res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erythrophleum Africanum
''Erythrophleum africanum'', the African blackwood, is a legume species in the genus ''Erythrophleum'' found in savannahs of tropical Africa. It produces a gum similar to gum arabic. The larvae of '' Charaxes phaeus'', the demon emperor, and of '' Charaxes fulgurata'', the lightning charaxes, feed on ''E. africanum''. This plant is toxic to herbivores. Phytochemical constituents detected in the leaves aqueous extracts are saponins, cardiac glycosides, tannins, flavonoid glycosides, free flavonoids and alkaloids. The plant also yields dihydromyricetin.

Larvae
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 ...

Miombo
The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located primarily in Central Africa. It includes four woodland savanna ecoregions (listed below) characterized by the dominant presence of ''Brachystegia'' and ''Julbernardia'' species of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss and produce a flush of new leaves just before the onset of the wet season with rich gold and red colours masking the underlying chlorophyll, reminiscent of autumn colours in the temperate zone. The woodland gets its name from ''miombo'' (plural, singular ''muombo''), the Bemba word for ''Brachystegia'' species. Other Bantu languages of the region, such as Swahili and Shona, have related if not identical words, such as Swahili ''miyombo'' (singular ...
