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] |
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.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

''Lethe'' is a butterfly genus from the subfamily Satyrinae in the family Nymphalidae. The genus was erected by Jacob Hübner in 1819.

Butterflies Of Sri Lanka
Sri Lanka is home to 245 species of butterflies with 23 of these being endemic to the island. Of the 245 species, 76, are listed as threatened nationally, while Ceylon Rose is designated as critically endangered. General description The majority of species are found in the foothills (up to elevation). A much smaller number of species are found above , while 20 species of butterfly are restricted to the low lying dry zone (below elevation). The number of butterflies peaks in two seasons during the year. The first of these is during the Southwestern monsoon in the months of March to April. The second is during the Northeastern monsoon which continues from September to October. Within Sri Lanka, thlatest revision of lepidopteransdescribed 1903 species with 58 families of butterflies and moths. Out of these 1903 species, 208 species are butterflies and 1695 species are moths. The family-wise number of butterfly species are : History of studies on butterflies The first s ...
