Potamarcha Congener
''Potamarcha congener'' is a species of dragonfly in the family Libellulidae. It was first described by Jules Pierre Rambur in 1842, almost fifty years before Friedrich Karsch described its genus. ''Potamarcha congener'' is one of two species making up the genus ''Potamarcha'', together with ''Potamarcha puella''. Distribution ''Potamarcha congener'' is common through much of its range, which stretches through parts of South Asia, South-East Asia, and Oceania, including in countries such as India, Indonesia, China, Australia, and Vietnam. Owing to its wide distribution, the species has been classified as Least Concern by the International Union for Conservation of Nature. Description and habitat ''Potamarcha congener'', known as a yellow-tailed ashy skimmer, common chaser, or swampwatcher, is a medium-sized dragonfly with a bluish black thorax and yellow tail with black markings. Face is olivaceous yellow to steel black or brown. Eyes are reddish brown above and bluish grey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Libellulidae
The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies. The genus ''Libellula'' is mostly New World, but also has one of the few endangered odonates from Japan: ''Libellula angelina''. Many of the members of this genus are brightly colored or have banded wings. The related genus ''Plathemis'' includes the whitetails. The genus ''Celithemis'' contains several brightly marked species in the southern United States. Members of the genus ''Sympetrum'' are called darters (or meadowhawks in North America) and are found throughout most of the world, except Australia. Several Southern Hemisphere species in the gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Karsch
Ferdinand Anton Franz Karsch or Karsch-Haack (2 September 1853, in Münster – 20 December 1936, in Berlin) was a German arachnologist, entomologist and anthropologist. The son of a doctor, Karsch was educated at the Friedrich Wilhelm University in Berlin and published a thesis on the gall wasp in 1877. From 1878 to 1921 he held the post of curator at the Museum für Naturkunde Berlin. Between 1873 and 1893, he published a catalogue of the spiders of Westphalia; he also published numerous articles on the specimens that the museum received from various explorers and naturalists working in Africa, in China, in Japan, in Australia, etc. This publication of others' work sometimes led to disputes over priority and nomenclature, for example with Pickard-Cambridge. Alongside his zoological activities, he published many works on sexuality and, in particular, homosexuality in both the animal kingdom and in so-called "primitive" peoples, including ''Das gleichgeschlechtliche Leben ...

University Of Puget Sound
The University of Puget Sound (UPS or Puget Sound) is a private university in Tacoma, Washington. The university draws approximately 2,600 students from 44 states and 16 countries. It offers 1,200 courses each year in more than 50 traditional and interdisciplinary areas of study. The university is affiliated with the United Methodist Church. History The University of Puget Sound was founded by the Methodist Episcopal Church in 1888 in downtown Tacoma. The idea for a college in Tacoma originated with Charles Henry Fowler, who had previously been the president of Northwestern University. Fowler was in Tacoma for a Methodist conference when he spoke of his vision of a Christian institution of learning in the area. The conference released a report: Two cities vied for the location of the school: Port Townsend and Tacoma. The committee eventually decided on Tacoma. A charter was drawn up and filed in Olympia on March 17, 1888. This date marks the legal beginning of the school. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odonata Of Australia
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The wo ...

Anisoptera Genera
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or a ...

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] |
