Victor Gurney Logan Van Someren
Victor Gurney Logan Van Someren (1886 in Melbourne – 24 July 1976) was a zoologist and entomologist. Van Someren was born in Australia. He attended George Watson's College and studied zoology at University of Edinburgh. He was also a dentist. Van Someren moved to Kenya in 1912 and lived in Nairobi. He was in the East Africa and Uganda Natural History Society and became Honorary Secretary. In 1930 he became Curator of the Coryndon Museum. Van Someren named a number of bird and butterfly species. Species named after him include the fish '' Labeobarbus somereni''.

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.

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 ...

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do no ...

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 ...

Peltophorum
''Peltophorum'' is a genus of 5–15 species of flowering plants in the family Fabaceae, subfamily Caesalpinioideae. The genus is native to certain tropical regions across the world. The species are medium-sized to large trees growing up to 15–25 m tall, rarely 50 m.Germplasm Resources Information Network''Peltophorum''Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . Etymology ''Peltophorum'' literally means "shield-bearing": from Greek (, " ''peltē'' shield"), with the interfix , '' -phor(os)'' ("bearing") and New Latin suffix . It is a reference to the peltate (shield-like) form of the plant's stigma.

Consortium For The Barcodes 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, ...

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 ...
