Polyura
:''for the monotypic genus of plants, see Polyura geminata'' ''Polyura'' is a subgenus of butterflies also referred to as Nawab butterflies and belonging to the Nymphalidae, brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. Like the large and conspicuous forest queens (subgenus ''Euxanthe''), they belong to the genus ''Charaxes'', unique genus of the tribe (biology), tribe Charaxini. Distribution ''Polyura'' butterflies are native to the Indomalayan realm, Indomalayan and Australasian realms. They are widespread from Pakistan to Okinawa Island, and from China to Pacific Islands (Fiji, New Caledonia, Vanuatu). Systematics * The subgenus ''Polyura'' was described by the Swedish naturalist Gustaf Johan Billberg in 1820. * The type species is ''Polyura pyrrhus'' (Carl Linnaeus, Linnaeus). Taxonomy The subgenus was revised in 1982 by Robert Leslie Smiles based on morphological characters. The genus ''Polyura'' was synonymized with the genus ''Charaxes'' in ...

Charaxes
The rajah and pasha butterflies, also known as emperors in Africa and Australia, (genus ''Charaxes'') make up the huge type genus of the Nymphalidae, brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. They belong to the tribe (biology), tribe Charaxini, which also includes the nawab butterflies (''Polyura''). ''Charaxes'' are tropical Old World butterflies, with by far the highest Species richness, diversity in sub-Saharan Africa, a smaller number from South Asia to Melanesia and Australia, and a single species (''Charaxes jasius, C. jasius'') in Europe. They are generally strong flyers and very popular among Insect collecting, 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.

Charaxinae
__NOTOC__ The Charaxinae, the leafwings, are a nymphalid subfamily of butterflies that includes about 400 species, inhabiting mainly the tropics, although some species extend into temperate regions in North America, Europe, China, and southern Australia. Significant variations exist between the species. For example, some are medium sized and bright orange above, but mottled gray or brown below. This underwing coloration helps them resemble a dead leaf when they are at rest, as they keep their wings closed. With relatively few exceptions, the hindwings of the members of this subfamily have jagged edges. Adults are very robust and fast flyers, and many are strongly attracted to drink liquids from carrion, dung, and rotten fruits, rather than nectar from flowers. Males establish territories and perch on tree trunks, branches, and even the ground. The eggs are smooth and round and generally with a somewhat concave apex. Some genera in this subfamily (notably ''Charaxes'', ''Agrias ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (; ), is an island country in Melanesia located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of Solomon Islands, and west of Fiji. Vanuatu was first inhabited by Melanesians, Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós, Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies and named it . In the 1880s, France and the United Kingdom of Great Britain and Ireland, United Kingdom claimed parts of the archipelago, and in 1906, they agreed on a framework for jointly managing the archipelago as the New Hebrides through an Anglo-French condominium (international law), condominium.

Australasia
Australasia is a subregion of Oceania, comprising Australia, New Zealand (overlapping with Polynesia), and sometimes including New Guinea and surrounding islands (overlapping with Melanesia). The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific ( Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colon ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeography
Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time. Organisms and biological community (ecology), communities often vary in a regular fashion along geographic gradients of latitude, elevation, allopatric speciation, isolation and habitat species-area curve, area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable Natural environment, environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy (bio ...

Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
