Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous 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, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...

Hesperiidae
Skippers are a group of butterflies placed in the family Hesperiidae within the order Lepidoptera (moths and butterflies). They were previously placed in a separate superfamily, Hesperioidea, but have since been placed in the superfamily Papilionoidea (the butterflies). They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly lack wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea. The third and rather small butterfly superfamily is the moth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Harry Evans
Brigadier William Harry Evans (born 22 July 1876 in Shillong – died 13 November 1956, Church Whitfield ) was a lepidopterist and British Army officer who served in India. He documented the butterfly fauna of India, Burma and Ceylon in a series of articles in the ''Journal of the Bombay Natural History Society''. Brigadier Evans was especially interested in the taxonomy (biology), taxonomy and systematics of the butterfly families Lycaenidae and Hesperiidae an example being his ''A revision of the Arhopala group of Oriental Lycaenidae (Lepidoptera: Rhopalocera)'' ''Bull. British Mus. (Nat. Hist.)'', Ent., vol. 5: pp. 85–141 (1957). Life and work Evans was the third son of Sir Horace Moule Evans and Elizabeth Anne, daughter of Surgeon General J. T. Tressider. His mother kindled an interest in nature and, when he was sent to King's School, Canterbury, he was already interested in butterfly, butterflies and moths. He joined the army at the age of 18 and was posted wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Evershed
John Evershed CIE FRS FRAS (26 February 1864 – 17 November 1956) was an English astronomer. He was the first to observe radial motions in sunspots, a phenomenon now known as the Evershed effect. Biography Evershed was born in Gomshall, Surrey to John and Sophia (née Price) Evershed. He made the discovery which bears his name while at Kodaikanal Observatory in 1909. After retirement in 1923 he set up a private observatory at Ewhurst, Surrey and built a large spectroheliograph of special design and another with high-dispersion liquid prism. He continued to study the wave-lengths of H and K lines in prominences, giving values of the solar rotation at high levels in different latitudes and at different phases of the solar cycle. Work continued until 1950 when the observatory closed and he presented some of his instruments to the Royal Greenwich Observatory at Herstmonceux. In the autumn of 1890 was a founding member of the British Astronomical Association. He directed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Swinhoe
Colonel Charles Swinhoe (27 August 1838 in CalcuttaAlthough many published sources give 1836, the India Office Records note it as 1838 (), the other year being that of his brother Robert. – 2 December 1923) was an English naturalist and lepidopterist, who served in the British Army in India. He was one of the eight founders of the Bombay Natural History Society and a brother of the famous naturalist Robert Swinhoe. Swinhoe was commissioned ensign in the 56th Regiment of Foot without purchase in 1855, serving in the Crimea and reaching India after the 1857 Mutiny. He exchanged into a lieutenancy in the 15th Foot without purchase in 1858 and returned to the 56th Foot in 1859, transferring to the Bombay Staff Corps later the same year. He was at Kandahar with Lord Roberts in 1880, and collected 341 birds there and on the march back to India. These were described in ''The Ibis'' (1882: 95–126). He was promoted lieutenant-colonel in 1881 and colonel in 1885. Swinhoe was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera Indica
''Lepidoptera Indica'' was a 10 volume work on the butterflies of the Indian region that was begun in 1890 and completed in 1913. It was published by Lovell Reeve and Co. of London. It has been considered the ''magnum opus'' of its author, Frederic Moore, assistant curator at the museum of the East India Company. Frederic Moore described a number of new species through this publication. Moore was a splitter, known for careless creation of synonyms, sometimes placing the same species in more than one genus. History The series was based on a large collection of butterflies that were under the care of the curator of the Asiatic Museum, Dr Thomas Horsfield. The museum was closed in 1879 and the collection was transferred to the British Museum. Moore in his preface defined the Indian region as being roughly bounded by the Himalayan mountains in the north, Suleiman and Hala mountains in the northwest, Ceylon to the South and Burma in the East and including the Andaman and Nicobar Isla ...
