Aeshnidae
The Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies. The family includes the largest dragonflies found in North America and Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia ... and among the largest dragonflies on the planet. Description Common worldwide or nearly worldwide genera are ''Aeshna'' and ''Anax (dragonfly), Anax''.

Most European species belong to ''Aeshna''. Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor.

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Dragonfly
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 ...

Australian Faunal Directory
The Australian Faunal Directory (AFD) is an online catalogue of taxonomic and biological information on all animal species known to occur within Australia. It is a program of the Department of Climate Change, Energy, the Environment and Water of the Government of Australia. By May 12, 2021, the Australian Faunal Directory has collected information about 126,442 species and subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species .... It includes the data from the discontinued ''Zoological Catalogue of Australia'' and is regularly updated. Started in the 1980s, it set a goal to compile a "list of all Australian fauna including terrestrial vertebrates, ants and marine fauna" and create an "Australian biotaxonomic information system".''Commonwealth Record'', Volume 5, Issues 26-34, p. 1 ...

Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by Parks Australia Division of Australia's Department of the Environment, Water, Heritage and the Arts (DEWHA). Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. Its purpose is to collate from the many libraries, museums and other collections the taxonomy of Australia's estimated 2 million species of flora and fauna, including aquatic species. These represent almost 20% of the earth's biodiversity, 80% of which are unique to Australia. ABRS has undertaken active funding for taxonomic research of Australia's biodiversity and is internationally recognised for its extensive data bases and publications. Publications The most important outputs of the ABRS has been the publication of the multi-volume ''Flora of Australia'' and '' Fauna of Australia'' series. Other output includes ''The Banksia Atlas'' and the "Platypus" database pa ... [...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] |
Aeshna
''Aeshna'', or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description These are relatively large dragonflies. Their thoraces and abdomens are brown in color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen. Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus '' Rhionaeschna''. The name ''Aeshna'' was coined by the Danish entomologist Fabricius in the 18th century. The name may have resulted from a printer's error in spelling the Greek ''Aechma'', "a spear". The spelling ''Aeschna'' has been intermittently used over a period of time, but is now abandoned for the original name ''Aeshna''. However, derived genus names (such as '' Rhionaeschna'') retain the 'sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...
