Pygaera Pigra
''Pygaera'' is a monotypic moth genus of the family Notodontidae erected by Ferdinand Ochsenheimer in 1810. Its only species, ''Pygaera timon'', was first described by Jacob Hübner in 1803. It is found in northern and central Europe, through eastern Asia up to Ussuri and Japan. The wingspan is 17–19 mm. The moth flies from May to July depending on the location. The larvae feed on ''Populus tremula'', ''Populus alba'' and ''Populus nigra ''Populus nigra'', the black poplar, is a species of Populus sect.

Ferdinand Ochsenheimer
Ferdinand Ochsenheimer (17 March 1767 – 2 November 1822) was a German actor and entomologist (lepidopterist). Life Ochsenheimer was born and brought up in Mainz (then in the Electorate of Mainz) and began to show an interest in butterflies and moths in his early youth. At the age of twelve he was apprenticed with a saddler but when his intellectual abilities were recognized friends of his father's enabled him to study natural history at the university. On 16 September 1788 he received his degree of ''Doktor der Philosophie''. He found employment as an educator with Stadtkommandant von Dallwigh in Mannheim, then with Baron von Reipelt. In Mannheim Ochsenheimer wrote his first stage comedies (''Er soll sich schlagen'', ''Der Brautschatz''). At the age of 27 he decided to follow a career as an actor and entered into Quandt's troupe of actors in Bayreuth. His first appearance was on 12 November 1794 as Flickwort in Gotter's ''Schwarzer Mann''. After trying his hand in several fi ...

Jacob Hübner
Jacob Hübner (20 June 1761 – 13 September 1826, in Augsburg) was a German entomologist. He was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. Scientific career Hübner was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. He was one of the first specialists to work on the European Lepidoptera. He described many new species, for example ''Sesia bembeciformis'' and ''Euchloe tagis'', many of them common. He also described many new genus, genera. He was a designer and engraver and from 1786 he worked for three years as a designer and engraver at a cotton factory in Ukraine. There he collected Butterfly, butterflies and moths including descriptions and illustrations of some in ''Beiträge zur Geschichte der Schmetterlinge'' (1786–1790) along with other new species from the countryside around his home in Augsburg. Hübner's masterwork "Tentamen" was intended as a discussion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Moth
Moths are a group of insects that includes all members of the order Lepidoptera that are not Butterfly, butterflies. They were previously classified as suborder Heterocera, but the group is Paraphyly, paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and Diurnal animal, diurnal species. Differences between butterflies and moths While the Butterfly, butterflies form a monophyly, monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae a ...

Notodontidae
Notodontidae is a family of moths with approximately 3,800 known species. The family was described by James Francis Stephens in 1829. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas, especially in the New World (Miller, 1992). Species of this family tend to be heavy-bodied and long-winged, the wings held folded across the back of the body at rest. They rarely display any bright colours, usually being mainly grey or brown, with the exception of the subfamily Dioptinae (Grimaldi and Engel, 2005). These features mean they rather resemble Noctuidae The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family (biology), family of moths. Taxonomically, they are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly ... although the families are not closely related.

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ussuri
The Ussuri ( ; ) or Wusuli ( ) is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China in the province of Heilongjiang. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860), until it joins the Amur as a tributary to it near Khabarovsk. It is approximately long. The Ussuri drains the Ussuri basin, which covers . Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is , and the average elevation is . Names The Ussuri has been known by many names. In Manchu, it was called the Usuri Ula or Dobi Bira (River of Foxes) and in Mongolian the Üssüri Müren. ''Ussuri'' is Manchu for ''soot-black river''. History * The Ussuri has a reputation for catastrophic floods. It freezes up in November and stays under the ice until April. The river teems with different kind ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus Tremula
''Populus tremula'' (commonly called aspen, common aspen, Eurasian aspen, European aspen, or quaking aspen) is a species of poplar native to cool temperate regions of the Old World. Description It is a substantial deciduous tree growing to tall by broad, with a trunk attaining over in diameter. The bark is pale greenish-grey and smooth on young trees with dark grey diamond-shaped lenticels, becoming dark grey and fissured on older trees. The adult leaves, produced on branches of mature trees, are nearly round, slightly wider than long, diameter, with a coarsely toothed margin and a laterally flattened petiole long. The flat petiole allows them to tremble in even slight breezes, and is the source of its scientific name, as well as one of its vernacular names "langues de femmes" attributed to Gerard's 17th-century ''Herball''. The leaves on seedlings and fast-growing stems of suckers (root sprouts) are of a different shape, heart-shaped to nearly triangular. They are al ...
