It is found in Italy, Spain, France, Germany, Denmark, Fennoscandia, Austria, Switzerland, Hungary, Bulgaria, the Czech Republic, Greece, Turkey, Belarus, the Baltic region, Siberia and from central Asia up to the Altai Mountains. Note that ''E. eruta'' may not be a good species.

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a 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 and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well est ...

Belarus
Belarus,, , ; alternatively and formerly known as Byelorussia (from Russian ). officially the Republic of Belarus,; rus, Республика Беларусь, Respublika Belarus. is a landlocked country in Eastern Europe. It is bordered by Russia to the east and northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Covering an area of and with a population of 9.4 million, Belarus is the 13th-largest and the 20th-most populous country in Europe. The country has a hemiboreal climate and is administratively divided into seven regions. Minsk is the capital and largest city. Until the 20th century, different states at various times controlled the lands of modern-day Belarus, including Kievan Rus', the Principality of Polotsk, the Grand Duchy of Lithuania, the Polish–Lithuanian Commonwealth, and the Russian Empire. In the aftermath of the Russian Revolution in 1917, different states arose competing for legitimacy amid the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euxoa
''Euxoa'' is a genus of moths of the family Noctuidae raised to Genus by the German entomologist, Jacob Hübner. The Genus is mostly confined to dry and semi dry areas in the Northern Hemisphere. There 130 species in Eurasia, a few in Africa, and 175 in North America. There are no species in the Genus in South-East Asia or in Australia. In North America, most species are found in Western regions. Of the North American species, 4 are endemic to Mexico. There is one species recorded from Chile, but this may be a mislabeled specimen. In real terms, species numbers do not equal species abundance. Some areas with few species have large numbers of the ones that do live there. In North America there are 7 subgenera - ''Chorizagrotis'', ''Palaeoeuxoa'', ''Heteroeuxoa'',''Longivesica'', ''Pleuonectopoda'', ''Orstagrotis'', and ''Euxoa''. The larvae of this ''Genus'' are Cutworms, living in the soil but feeding on the surface. A few species also climb. Most larval Euxoa hatch from eggs ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other 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 distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design an ...

Euxoa Nigrofusca
The white-line dart (''Euxoa nigrofusca'') is a moth of the family Noctuidae. It is found from Europe, to southern Siberia, central Asia to the Pacific Ocean. In North Africa it is known from Morocco and Algeria. Description The wingspan is 28–40 mm. Colouring and pattern are extremely variable and hardly a specimen has an identical colouring and pattern. The colour varies from grey-brown to dark grey. The costa is pale and the pattern often obscure. Pale orbicular and reniform. The males have relatively short combed antennae, the female antennae are thread-like. Note that ''E. nigrofusca'' may not be a good species. The ''Euxoa tritici'' complex consists of five sibling species in Europe: White-linedart '' Euxoa tritici'' (Linnaeus, 1761), ''Euxoa nigrofusca'' (Esper, 1788), '' Euxoa eruta'' (Hübner, 1817), ''Euxoa diaphora'' Boursin, 1928 and ''Euxoa segnilis'' (Duponchel, 1836).

Species Problem
The species problem is the set of questions that arises when biologists attempt to define what a species is. Such a definition is called a species concept; there are at least 26 recognized species concepts. A species concept that works well for sexually reproducing organisms such as birds may be useless for species that reproduce asexually, such as bacteria. The scientific study of the species problem has been called microtaxonomy. One common, but sometimes difficult, question is how best to decide which species an organism belongs to, because reproductively isolated groups may not be readily recognizable, and cryptic species may be present. There is a continuum from ''reproductive isolation'' with no interbreeding, to ''panmixis'', unlimited interbreeding. Populations can move forward or backwards along this continuum, at any point meeting the criteria for one or another species concept, and failing others. Many of the debates on species touch on philosophical issues, such as nom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altai Mountains
The Altai Mountains (), also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E. The region is inhabited by a sparse but ethnically diverse population, including Russians, Kazakhs, Altais, Mongols and Volga Germans, though predominantly represented by indigenous ethnic minorities of semi-nomadic stock. The local economy is based on bovine, sheep, horse husbandry, hunting, agriculture, forestry, and mining. The Altaic language family takes its name from this mountain range. Etymology and modern names ''Altai'' is derived from underlying form *''altañ'' "gold, golden" (compare Old Turkic 𐰞𐱃𐰆𐰣 ''altun'' ...

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of nort ...
