Rustic Shoulder-knot
''Apamea sordens'', the rustic shoulder-knot or bordered apamea, is a moth of the family Noctuidae. The species was first described by Johann Siegfried Hufnagel in 1766. It is distributed throughout Europe, east across the Palearctic to Central Asia and to China and Japan. It also occurs in North America (Labrador to Virginia, west across Canada, south to Minnesota). This moth has a wingspan of 36 to 42 mm. The forewings are brown with mostly indistinct markings except for the narrow black mark at the base of the wing which gives the species its common name. The hindwings are greyish brown, darker towards the margins, with prominent dark venation. This moth flies at night and is attracted to light and sugar. Technical description and variation Forewing dull lilac grey, flushed with fawn colour, especially in median area; a black, semibifid streak from base below cell; lines brownish, double, indistinct; the median shade dark grey or fawn colour, diffuse and prominent; orbic ...

Johann Siegfried Hufnagel
Johann Siegfried Hufnagel (17 October 1724, Uckerfelde, Falkenwalde, Prenzlau district, Brandenburg – 23 February 1795, Langenfeld, Sternberg district) was a German parson and entomologist (lepidopterist). Life Until the late 20th century nothing was known about Hufnagel's life. Even his first names remained unknown. In 1987 Gerstberger and Stiesy succeeded in identifying him with the help of Fischer's work (1941) and uncovered some basic biographical information. Hufnagel came from a family of Protestantism, Protestant clergymen, his father and grandfather before him having been parsons. Johann Siegfried probably attended one of the universities in northern or eastern Germany (but not in Berlin as Berlin had no university at the time). From 1759 to 1767 the Berlin address book mentions one "Hufnagel" or "Huffnagel" who was praeceptor (teacher) at the Protestant-Lutheranism, Lutheran church near the ''Grosses Friedrichs-Hospital und Waisenhaus'' (hospital and orphanage) and lived ...

Buckler W The Larvæ Of The British Butterflies And Moths PlateLXVII
A buckler (French ''bouclier'' 'shield', from Old French ''bocle, boucle'' 'boss') is a small shield, up to 45 cm (up to 18 in) in diameter, gripped in the fist with a central handle behind the boss. It became more common as a companion weapon in hand-to-hand combat during the Medieval and Renaissance periods. Its size made it poor protection against missile weapons (e.g., arrows) but useful in deflecting the blow of an opponent's weapons, binding their arms, hindering their movements, or punching them. The seminal study of the topic has been undertaken by Herbert Schmidt and has devised the following typology: * Type I: round * Type II: rectangular or trapezoidal * Type III: oval or teardrop shaped with the cross-section of the buckler further refining these types: * Type a: flat * Type b: concave * Type c: convex * Type d: wavy The combination of the two classifiers determines the buckler type. Thus a Type Ia buckler is a round flat buckler; a Type IId buckler is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the tropical and subtropical grasslands, savannas, and shrublands biome * the temperate grasslands, savannas, and shrublands biome A steppe is usually covered with grass and shrubs, depending on the season and latitude. The term ''steppe climate'' denotes a semi-arid climate, which is encountered in regions too dry to support a forest, but not dry enough to be a desert. Steppes are usually characterized by a semi-arid or continental climate. Temperature extremes can be recorded in the summer of up to and in winter of down to . Besides this major seasonal difference, fluctuations between day and night are also significant: in both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night.

Siberian Steppe
Siberia ( ; , ) is an extensive region, geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy Russian conquest of Siberia, conquest of Siberia, which began with the Conquest of the Khanate of Sibir, fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukchi Peninsula, Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural (river), Ural River usually forming the southernmost po ...

Wild Rice
Wild rice, also called manoomin, mnomen, psíŋ, Canada rice, Indian rice, or water oats, is any of four species of grasses that form the genus ''Zizania'', and the grain that can be harvested from them. The grain was historically and is still gathered and eaten in North America and, to a lesser extent, China, where the plant's stem is used as a vegetable. Wild rice and domesticated rice (''Oryza sativa'' and '' Oryza glaberrima''), are in the same botanical tribe Oryzeae. Wild-rice grains have a chewy outer sheath with a tender inner grain that has a slightly vegetal taste. The plants grow in shallow water in small lakes and slow-flowing streams; often, only the flowering head of wild rice rises above the water. The grain is eaten by dabbling ducks and other aquatic wildlife. Species Three species of wild rice are native to North America: * Northern wild rice (''Zizania palustris'') is an annual plant native to the Great Lakes region of North America, the aquatic areas ...

Wheat
Wheat is a group of wild and crop domestication, domesticated Poaceae, grasses of the genus ''Triticum'' (). They are Agriculture, cultivated for their cereal grains, which are staple foods around the world. Well-known Taxonomy of wheat, wheat species and hybrids include the most widely grown common wheat (''T. aestivum''), spelt, durum, emmer, einkorn, and Khorasan wheat, Khorasan or Kamut. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC. Wheat is grown on a larger area of land than any other food crop ( in 2021). World trade in wheat is greater than that of all other crops combined. In 2021, world wheat production was , making it the second most-produced cereal after maize (known as corn in North America and Australia; wheat is often called corn in countries including Britain). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of ...

Phalaris
Phalaris () was the tyrant of Akragas (now Agrigento) in Sicily in Magna Graecia, from approximately 570 to 554 BC. History Phalaris was renowned for his excessive cruelty. Among his alleged atrocities is cannibalism: he was said to have eaten suckling babies. Another expression of his sadistic brutality is that he supposedly ordered a sculptor named Perilaus to make him a brazen hollow bull. The bull could hold a man and was used as an execution machine. The condemned person was placed inside, then the bull was closed and a fire lit underneath. The sculpture was made in such a way that, while the condemned met a horrible death in the burning furnace, their cries were said to sound like the bellowing of a bull. Phalaris was entrusted with the building of the temple of Zeus Atabyrius in the citadel and took advantage of his position to make himself tyrant. Under his rule, Agrigentum seemed to have attained considerable prosperity. He supplied the city with water, adorned it w ...

Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus '' Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640. Fescue pollen is a significant contributor to hay fever. Taxonomy The genus ''Festuca'' represents a major evolutionary line of ...
