Vestalis Gracilis
''Vestalis gracilis'', is a species of damselfly belonging to the family Calopterygidae. It is known commonly as the clear-winged forest glory or clear-winged flash-wing. It is native to Southeast Asia and surrounding regions. Description The male and female are similar in size; the male having an abdomen 45 to 46 millimeters long and a hindwing 34 to 38 millimeters long and the female with an abdomen 43 to 50 millimeters long and a hindwing 36 to 39 millimeters long. The male is iridescent green with a yellow and black underside. It has brown legs and blue-tinged transparent wings. The eyes are dark brown above and greenish yellow below.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, but the ...

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 opini ...

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 (compared to about 44 mm in the common bluetail damselfly, '' Ischnura elegans''), are often metallic-coloured, and can be differentiated from other damselflies by the broader connection between the wings and the body, as opposed to the abrupt narrowing seen in other damselfly families. The family contains some 150 species. The Calopterygidae are found on every continent except Antarctica. They live along rivers and streams.Córdoba-Aguilar, A. & Cordero-Rivera, A. (2005)Evolution and ecology of Calopterygidae (Zygoptera: Odonata): status of knowledge and research perspectives.''Neotrop. Entomol'' 34(6), 861-879. Etymology The name is derived from Greek ''kalos'' meaning beautiful and ''ptery'' meaning winged. Characteristics The adults have metallic bo ...

Southeast Asia
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical United Nations geoscheme for Asia#South-eastern Asia, south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of atolls of Maldives, 26 atolls of Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is completely in the Northern Hemisphere. East Timor and the southern portion of Indonesia are the only parts that are south of the Equator. Th ...

Vestalis Apicalis
''Vestalis apicalis'', or the black-tipped forest glory, is a species of damselfly belonging to the family Calopterygidae. It is found in India and Sri Lanka. Subspecies ''V. apicalis apicalis'' is commonly found in the hill streams of Western Ghats. Two more subspecies are recognised; ''V. a. nigrescens'' Fraser 1929 from Sri Lanka and ''V. a. submontana'' Fraser 1934 from India. Records of ''V. a. submontana'' are from the Nilgiri Hills and Eastern Ghats. ''V. a. nigrescens'' is confined to Sri Lanka, where it appears to be quite widely distributed. ''V. a. submontana'' is now considered as a separate species ''Vestalis submontana''. Description and habitat It is a large metallic emerald-green colored damselfly with brown capped yellowish green eyes. The apices of all wings are broadly tipped with blackish-brown. Female is similar to the male; but dull colors and the apical marking usually paler and less sharply defined. It breeds in forest streams. Commonly seen as a grou ...

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 ...

Vestalis Submontana
''Vestalis submontana'' is a species of damselfly belonging to the family Calopterygidae. It is principally found in the Western Ghats of India, with some records further east. Frederic Charles Fraser described two new subspecies ''Vestalis gracilis amaena'' and ''Vestalis apicalis amaena'' in 1929 and later gave replacement names ''Vestalis gracilis montana'' and ''Vestalis apicalis submontana'' in 1934. The type specimens were from Nilgiri mountains in Western Ghats of South India. Matti Hämäläinen studied the type specimens of these taxa and other material preserved in collections of BMNH (London), IRSN (Brussels) and RMNH (Leiden) in 2011. He concluded that there is striking structural and colour differences which indicate that ''submontana'' is a distinct species. And its sympatric occurrence with ''V. apicalis'' and ''V. gracilis'' alone rules out its former subspecies status. So ''V. a. submontana'' is now considered as a separate species ''Vestalis submontana'' F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
