Description Male upperside very dark Vandyke brown; forewing uniform: hindwing with a postdiscal series of three or four blind black ocellar spots. Underside, brown; forewing below vein 2 and terminal margin paler, a broad band across the cell, the wing medially and at apex suffused with lilac, bearing an incurved postdiscal series of five, blind black ocelli.

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] |
Satyrinae
The Satyrinae, the satyrines or satyrids, commonly known as the browns, are a subfamily of the Nymphalidae (brush-footed butterflies). They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. The true number of the Satyrinae species is estimated to exceed 2,400. Overview They are generally weak fliers and often shun bright sunlight, preferring moist and semishaded habitats. The caterpillars feed chiefly on monocotyledonous plants such as palms, grasses, and bamboos. The Morphinae are sometimes united with this group. The taxonomy and systematics of the subfamily are under heavy revision. Much of the early pioneering work of L. D. Miller has helped significantly by creating some sort of order. '' Dyndirus'' (Capronnier, 1874) is a satyrid ''incertae sedis''. Other than this genus, according to the latest studies on the classification of Nymphalidae, all satyrines have been assigned to one of t ...

South India
South India, also known as Dakshina Bharata or Peninsular India, consists of the peninsular southern part of India. It encompasses the Indian states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, and Telangana, as well as the union territories of Lakshadweep and Puducherry, comprising 19.31% of India's area () and 20% of India's population. Covering the southern part of the peninsular Deccan Plateau, South India is bounded by the Bay of Bengal in the east, the Arabian Sea in the west and the Indian Ocean in the south. The geography of the region is diverse with two mountain ranges – the Western and Eastern Ghats – bordering the plateau heartland. The Godavari, Krishna, Kaveri, Tungabhadra, Periyar, Bharathappuzha, Pamba, Thamirabarani, Palar, and Vaigai rivers are important perennial rivers. The majority of the people in South India speak at least one of the four major Dravidian languages: Tamil, Telugu, Malayalam and Kannada (all 4 of which are among the 6 Classic ...

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 ...

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederic Moore
Frederic Moore FZS (13 May 1830 – 10 May 1907) was a British entomologist and illustrator. He produced six volumes of ''Lepidoptera Indica'' and a catalogue of the birds in the collection of the East India Company. It has been said that Moore was born at 33 Bruton Street, but that may be incorrect given that this was the address of the menagerie and office of the Zoological Society of London from 1826 to 1836. Moore was appointed an assistant in the East India Company Museum London from 31 May 1848 on a "disestablished basis" and became a temporary writer and then an assistant curator at the East India Museum with a pension of £330 per annum from 31 December 1879. He had a daughter Rosa Martha Moore. He began compiling ''Lepidoptera indica'' (1890–1913), a major work on the butterflies of the South Asia in 10 volumes, which was completed after his death by Charles Swinhoe. Many of the plates were produced by his son while some others were produced by E C Knight and John ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
