Protosticta Sanguinostigma
''Protosticta sanguinostigma'', the red spot reedtail, is a damselfly species in the family Platystictidae. It is endemic to Western Ghats in India. It is known to occur only in a few localities. Description and habitat It is a large slender damselfly with eyes bottle-green above and pale green below separated by an equatorial band of reddish-brown. Its thorax is glossy bronze-black on dorsum and pale blue on the sides. There is a narrow stripe of black bordered with brown across the anterior border of the metepimeron. Wings are transparent with blood-red pterostigma. Abdomen is dark-brown on dorsum and paler on the sides. Segment 1 and 2 are marked with white laterally. Segments 3 to 6 have broad distal black annules. Segments 4 to 7 have broader blue basal annules. Segment 8 is turquoise-blue with black apical border. Segments 9 and 10 are entirely black. Anal appendages are black. Female is similar to the male; but much shorter and stouter built. It is found in first and seco ...

Frederic Charles Fraser
''For others uses see Frederick Fraser (other)'' Frederic Charles Fraser (15 February 1880, in Woolwich – 2 March 1963, in Linwood was an English entomologist who specialised in Odonata. Following army service in India as a surgeon with the rank of lieutenant colonel, Fraser devoted himself entirely to dragonflies, mostly in the British Museum (Natural History), where his collection is maintained. Fraser's correspondence with A. Eric Gardner is in the library of the Natural History Museum, London. Fraser's correspondence with the Irish odonatologist Niall McNeill Niall MacNeill (1899–1969) was an Irish army officer and entomologist who specialised in Odonata and Heteroptera. He was the son of Eoin MacNeill, founder of the Irish Volunteers, which Niall MacNeill joined later becoming an officer in the Ir ... is in the Oxford University Museum.

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, bu ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Platystictidae
Platystictidae is a family of damselflies, commonly known as shadowdamsels. They look very similar to the threadtail damselfly family (Protoneuridae). They can mostly be found throughout Asia, Central America, and South America. Most members of this family live in dense forests in the tropics where they are found around streams. Their wings are narrow and their abdomen slender and elongated. The adults probably do not disperse far as many species are known from a single location or have small ranges and there are probably other species as yet undescribed. The oldest members of the family belong to the genus '' Mesosticta'' from the Cenomanian aged Burmese amber Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. ... of Myanmar.

Endemic
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] |
India
India, officially the Republic of India ( Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Th ...

Pterostigma
The pterostigma (plural: pterostigmata) is a group of specialized cells in the outer wings of insects, which are often thickened or coloured, and thus stand out from other cells. It is particularly noticeable in dragonflies, but present also in other insect groups, such as snakeflies, hymenopterans, and megalopterans. Purpose The pterostigma, a heavier section of the wing than nearby sections, assists in gliding. Without the pterostigmata, self-exciting vibrations known as flutter would set in on the wing above a certain critical speed, making gliding impossible. Tests show that with the pterostigmata, the critical gliding speed is increased 10–25% on one species of dragonfly. Pseudopterostigma Some female damselflies in the family Calopterygidae The Calopterygidae are a family of damselflies, in the suborder Zygoptera. They are commonly known as the broad-winged damselflies, demoiselles, or jewelwings. These rather large damselflies have wingspans of 50–80 mm (c ...
