Amanda's Blue
''Polyommatus amandus'', the Amanda's blue, is a butterfly of the family Lycaenidae. It is found in the Palearctic realm. Description With a wingspan of , Amanda's blue is noticeably larger than most of the "blue" butterflies, which is particularly apparent when they are flying. The upperside of the male's wings is a silvery blue or sky blue, often, but not always, with a broad dark border and a narrow black marginal line with an outermost white line. The upperside of the female's wings is in some populations dark blue edged with brown but in other populations is medium brown with a row of orange half-moon shaped lunules near the edges. The hind margin has red blotches. The underside of the male's wings are light grey with white-edged black blotches. The underside of the female's wings is similar but they are a rich creamy-brown colour with red blotches, especially on the margins of the hindwings and a series of black spots with white rims, often touching, forming a row parallel ...

Johann Gottlob Schneider
Johann Gottlob Theaenus Schneider (18 January 1750 – 12 January 1822) was a German classicist and naturalist. Biography Schneider was born at Collm in Saxony. In 1774, on the recommendation of Christian Gottlob Heine, he became secretary to the famous Strasbourg scholar Richard François Brunck, and in 1811, became professor of ancient languages and eloquence at Breslau (chief librarian, 1816) where he died in 1822. Works Of his numerous works the most important was his ''Kritisches griechisch-deutsches Handwörterbuch'' (1797–1798), the first independent work of the kind since Stephanus's ''Thesaurus'', and the basis of F. Passow's and all succeeding Greek lexicons (including, therefore, the contemporary standard ''A Greek-English Lexicon''). A special improvement was the introduction of words and expressions connected with natural history and science. In 1801, he corrected and expanded re-published Marcus Elieser Bloch's ''Systema Ichthyologiae iconibus cx illustratu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ I ...

Polyommatus
''Polyommatus'' is a genus of butterfly, butterflies in the family Lycaenidae. Its species are found in the Palearctic realm. Taxonomy Recent molecular studies have demonstrated that ''Cyaniris'', ''Lysandra (butterfly), Lysandra'', and ''Neolysandra'' are different genera from ''Polyommatus'', where they had been included, sometimes as subgenera. Some authors still recognize other subgenera, such as ''Agrodiaetus'', ''Bryna'', ''Meleageria'', and ''Plebicula''.

Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to extract essential nutrients present at low concentrations. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. In addition to various sugars, honeydew contains small amounts of amino acids, other organic compounds, and inorganic Salt (chemistry), salts with its precise makeup affected by factors such as insect species, host plant species, and whether a symbiotic organism is present. Honeydew-producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap; the excess fluid released by ci ...

Vicia Cracca
''Vicia'' is a genus of over 240 species of flowering plants that are part of the legume family (Fabaceae), and which are commonly known as vetches. Member species are native to Europe, North America, South America, Asia and Africa. Some other genera of their subfamily Faboideae also have names containing "vetch", for example the vetchlings (''Lathyrus'') or the milk-vetches (''Astragalus''). The lentils are included in genus ''Vicia'', and were formerly classified in genus ''Lens''. The broad bean (''Vicia faba'') is sometimes separated in a monotypic genus ''Faba''; although not often used today, it is of historical importance in plant taxonomy as the namesake of the order Fabales, the Fabaceae and the Faboideae. The tribe Vicieae in which the vetches are placed is named after the genus' current name. The true peas (''Pisum'') are among the closest living relatives of vetches. Use by humans Bitter vetch ('' V. ervilia'') was one of the first domesticated crops. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lathyrus Pratensis
''Lathyrus pratensis'' or meadow vetchling, yellow pea, meadow pea and meadow pea-vine, is a perennial legume that grows to 1.2 m in height. The hermaphrodite flowers are pollinated by bees. As a perennial, this plant reproduces itself over many years, spreading out from the point it was introduced, especially in damp grassy areas. This plant has been propagated in the past as animal fodder. ''Lathyrus pratensis'' is also a host plant for ovipositioning of the wood white butterfly (''Leptidea sinapis''). Description Meadow vetchling is a perennial plant with a limp, unwinged stem that grows to and is erect and hairy. The leaves are alternate with short stalks and large stipules. The leaf blades are pinnate with a single pair of broad lanceolate leaflets with blunt tips, entire margins and a terminal unbranched tendril. The inflorescence In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch o ...

Russian Far East
The Russian Far East ( rus, Дальний Восток России, p=ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ) is a region in North Asia. It is the easternmost part of Russia and the Asia, Asian continent, and is coextensive with the Far Eastern Federal District, which encompasses the area between Lake Baikal and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundary, maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast. Although the Russian Far East is often considered as a part of Siberia abroad, it has been historically categorized separately from Siberia in Russian regional schemes (and previously during the history of the Soviet Union, Soviet era when it was called the Soviet Far East). Terminology In Russia, the region is usually referred to as simply th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adalbert Seitz
Friedrich Joseph Adalbert Seitz, (24 February 1860 in Mainz – 5 March 1938 in Darmstadt) was a German physician and entomologist who specialised in Lepidoptera. He was a director of the Frankfurt zoo from 1893 to 1908 and is best known for editing the multivolume reference on the butterflies and larger moths of the world ''Die Gross-Schmetterlinge der Erde'' which continued after his death. Biography Seitz was born in Mainz and went to school in Aschaffenburg, Darmstadt and Bensheim. He studied medicine from 1880 to 1885 and then zoology at Giessen. His doctorate was on the protective devices of animals. He worked as an assistant in the maternity hospital of the University of Giessen and then worked as a ship's doctor from 1887, travelling to Australia, South America and Asia. He began to collect butterflies on these travels. In 1891 he habilitated in zoology with a thesis on the biology of butterflies from the University of Giessen. In 1893 he took up a position as a director ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...
