Hermann August Hagen
Hermann August Hagen (30 May 1817 – 9 November 1893) was a German entomologist who specialised in Neuroptera and Odonata. He had established himself as one of Europe's preeminent entomologists by 1867 when he accepted a position at Harvard University to curate the Museum of Comparative Zoology. In 1870 he became the first entomologist in the United States to hold the formal title, Professor of Entomology. Biography Hagen was born 30 May 1817 in Königsberg, Prussia. He was the son of Anna (Linck) Hagen and Carl Heinrich Hagen. His father was a senior government counselor and a professor of political science at the University of Königsberg and his grandfather, Karl Gottfried Hagen, was a professor of chemistry at the same university.Henshaw (1894) Young Hagen graduated from a gymnasium in 1836 and began to study medicine at the University of Königsberg. His course of studies was greatly influenced by his zoology professor, Martin Heinrich Rathke and together they toured maj ...

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 ...

Megapodagrionidae
The Megapodagrionidae are a family Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Idea ... of damselflies, commonly called flatwings for their habit of spreading out the hind wings horizontally when at rest. A 2013 phylogenetic analysis pares down this family into only three genera, and numerous other genera are now placed in different families, including Amanipodagrionidae, Argiolestidae, Heteragrionidae, Hypolestidae, Lestoideidae, Mesagrionidae, Mesopodagrionidae, Philogeniidae, Philosinidae, Protolestidae, Rhipidolestidae, Tatocnemididae, and Thaumatoneuridae.

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] |
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] |
Pruinescence
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...

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 ...

Insects Of Australia
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Hermann August Hagen
In biology, a taxon (back-formation from ''Taxonomy (biology), 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 Taxonomic rank, 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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu.
