Erythromma Najas
''Erythromma najas'', the red-eyed damselfly, is a member of the Coenagrionidae family of damselflies. Appearance The species is a small damselfly, long, predominantly black with iridescent blue markings. The male resembles blue-tailed damselflies (''Ischnura'' species) but is distinguished by its large, spaced eyes that are a deep red. It is very similar to the small red-eyed damselfly (''Erythromma viridulum'').

Erythromma Viridulum
The small red-eyed damselfly (''Erythromma viridulum'') is a member of the damselfly family Coenagrionidae. It is very similar to the red-eyed damselfly. Appearance The species is a small damselfly, about long, predominantly black with iridescent blue markings. Its large, spaced eyes are a deep red. Like the red-eyed damselfly, both sexes lack pale spots behind the eyes and have pale brown pterostigmata. The male has a bronze-black top and blue sides. The sides of the female's thorax are yellow, green or blue. The rear edge of the pronotum is rounded. Viewed from the side, the second and eighth segment of the abdomen of the male are mostly blue, which distinguishes it from the red-eyed damselfly where these are mostly black. Breeding This damselfly breeds in ponds, lakes and ditches and, in continental Europe, sluggish rivers. It seems to be well able to tolerate brackish water. It seems to be associated with floating vegetation such as Hornwort and Water Milfoil (''Myriophy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erythromma Lindenii
The goblet-marked damselfly (''Erythromma lindenii'') is a medium-sized blue-and-black (or green-and-black) damselfly in the pond damselfly family (Coenagrionidae). It's a fairly common species in the South and West of Europe but is not found in the British Isles, Scandinavia and Eastern Europe. ''Erythromma lindenii'' was previously known as ''Coenagrion lindenii'' and ''Cercion lindenii''. The goblet-marked damselfly is also known as the blue-eye. It's an easily recognized species, with its wide antehumeral stripes, narrow postocular spots, the male's very bright-blue eyes. He has very long and curved appendages, and the spear-shaped marks on S3-S6 of his abdomen. It can also be found in Asia: Russian Federation and it is also found in Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surf ... [...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 ...

Coenagrionidae
The insect family Coenagrionidae is placed in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family. The family Coenagrionidae has six subfamilies: Agriocnemidinae, Argiinae, Coenagrioninae, Ischnurinae, Leptobasinae, and Pseudagrioninae. This family is referred to as the narrow-winged damselflies or the pond damselflies. The Coenagrionidae enjoy a worldwide distribution, and are among the most common of damselfly families. This family has the smallest of damselfly species. More than 110 genera of the family Coenagrionidae are currently accepted.Integrated Taxonomic Information System (2007)Coenagrionidae retrieved November 4, 2007. Etymology The name may be derived from Greek ''coen'' meaning shared or common and ''agrio'' meaning fields or wild. Characteristics * Usually have a black pattern * Ground c ...

Toussaint De Charpentier
Toussaint von Charpentier (22 November 1779 – 4 March 1847) was a German geologist and entomologist. He was the author of ''Libellulinae europaeae descriptae e depictae'' (1840). Biography Toussaint von Charpentier was born in Freiberg, Saxony ( 22 November 1779 and died in Brieg 4 March 1847. Charpentier was the son of the Saxony geologist and "Berghauptmann" (head of the mining inspectorate), Johann Friedrich William von Charpentier and the brother of Johann von Charpentier. He studied geology and mining engineering at the Bergakademie Freiberg and continued his studies at the University of Leipzig. In the year 1802 Charpentier went to Prussia, where he accepted a place with the Silesia Oberbergamt (upper mining authority) in Breslau. Charpentier took over the management of Schweidnitz local mining authority in Schweidnitz until returning, in 1811, to the upper mining authority in Breslau. In 1828 his transfer to Dortmund as "Vizeberghauptmann" took place. 1830 he w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Taxa Named By Toussaint De Charpentier
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
