Butterflies Of Singapore
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 fli ...

Papilio
''Papilio'' is a genus in the swallowtail butterfly family, Papilionidae, as well as the only representative of the tribe Papilionini. The word ''papilio'' is Latin for butterfly. It includes the common yellow swallowtail (''Papilio machaon''), which is widespread in the Northern Hemisphere and the type species of the genus, as well as a number of other well-known North American species such as the western tiger swallowtail ('' Papilio rutulus''). Familiar species elsewhere in the world include the Mormons ('' Papilio polytes'', '' Papilio polymnestor'', '' Papilio memnon'', and '' Papilio deiphobus'') in Asia, the orchard and Ulysses swallowtails in Australia (''Papilio aegeus'', '' Papilio ulysses'', respectively) and the citrus swallowtail of Africa (''Papilio demodocus''). Older classifications of the swallowtails tended to use many rather small genera. More recent classifications have been more conservative, and as a result a number of former genera are now absorbed within ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ...

Entomological Magazine
The ''Entomological Magazine'' is a publication devoted to entomology. The ''Entomological Magazine'' was published between September 1832 and October 1838 by the Society of Entomologists of London. The editor was Edward Newman aided by Francis Walker.The work includes reviews of entomological literature, articles and systematic papers in which new species are described. Contributors include John Curtis, Edward Doubleday ("Communications on the Natural History of North America."), Alexander Henry Haliday (notably An essay on the classification of the parasitic Hymenoptera... of Britain which correspond with the Ichneumones minuti of Linnaeus), George Robert Waterhouse, John Obadiah Westwood, William John Swainson, Francis Walker ( notably Monographia Chalciditum ), George Thomas Rudd, William Edward Shuckard, James Charles Dale, James Francis Stephens and Frederick William Hope The ''Entomological Magazine'' was discontinued following controversy. Newman writes a "Valedict ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ...

Papilio Nubilus
''Papilio nubilus'' is a rare species of swallowtail butterfly from the genus ''Papilio'' that can be found in Borneo. Previously listed as a distinct species ( D'Abrera 1982, Munroe 1961), but now regarded (by Collins & Morris 1985, Tsukada & Nishiyama 1982: 307) as an interspecific hybrid between ''Papilio nephelus'' and ''Papilio polytes''. Subspecies *''Papilio nubilus nubilus'' (northern Borneo) *''Papilio nubilus musianus'' Rothschild, 1899 (Upper Palembang district) Taxonomy ''Papilio nubilus'' is a member of the ''helenus'' species-group.

Swallowtail Butterfly
Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus '' Ornithoptera''. Swallowtails have a number of distinctive features; for example, the papilionid caterpillar bears a repugnatorial organ called the osmeterium on its prothorax. The osmeterium normally remains hidden, but when threatened, the larva turns it outward through a transverse dorsal groove by inflating it with fluid. The forked appearance in some of the swallowtails' hindwings, which can be seen when the butterfly is resting with its wings spread, gave rise to the common name ''swallowtail''. As for its formal name, Linnaeus chose ''Papilio'' for the type genus, as ''papilio'' is Latin for "butterfly". For the specific epithets of the genus, Linnaeus applied ...

Papilio Nephelus
''Papilio nephelus'' is a species of swallowtail butterfly belonging to the family Papilionidae. Subspecies include ''P. n. chaon'', the yellow Helen, and ''P. n. sunatus'', the black and white Helen. Description ''Papilio nephelus'' has a wingspan reaching about . The basic colour of the wings is black, with a chain of white spots on the forewing and a large white or yellow area on the hindwing. The underside and the upperside of the wings in this species are very similar. The hindwings have wavy margins, with long tails. The thorax and the abdomen are black. ''Papilio nephelus'' superficially closely resembles '' P. helenus''. The differences are, however, both of structure and of colour. Male forewing upperside: entirely without the thick coating of short hairs on the outer half. Upperside: black with a sprinkling of yellowish-brown scales on the forewing, that form four longitudinal streaks on the cell and internervular streaks on the outer half. Hindwing: the upper discal ...
