Erebia Melampus
''Erebia melampus'', the lesser mountain ringlet, is a member of the subfamily Satyrinae of the family Nymphalidae. Distribution and habitat This European endemic species occurs in the Alps from the Maritime Alps to eastern Austria (France, Germany, Italy, Liechtenstein, Switzerland and Austria). It prefers grassy places, in woodland or in open areas, at an elevation of above sea level. Description The wingspan is 30–36 mm. These small butterflies have brown wings. Forewings show a postmedian band of orange oval to round markings containing small black spots. Hindwings have three or four postdiscal eyespots. Description in Seitz ''E. melampus'' Fuessl.

Johann Kaspar Füssli
Johann Kaspar Füssli, also written Johann Caspar Fuesslins or Fuessly (9 March 1743 – 4 May 1786), was a Swiss painter, entomologist and publisher. He was born in Zurich, the son of Johann Caspar Füssli (1706–1782) and Anna Elisabeth Waser. He was thus the brother of Henry Fuseli (Johann Heinrich Füssli, 1745–1825). He married twice: to Verena Störi in 1770, and Anna Elisabeth Kilchsperger in 1774. The only spider species he described (as Fuesslin, 1775) is the "daddy long-legs spider", ''Pholcus phalangioides'', also known as "cellar spider".

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Of Europe
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most 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, and after its wings have expanded and dried, it fli ...

Erebia
''Erebia'' is a Holarctic genus of brush-footed butterflies, family Nymphalidae. Most of the about 90–100 species (see also below) are dark brown or black in color, with reddish-brown to orange or more rarely yellowish wing blotches or bands. These usually bear black spots within, which sometimes have white center spots. This genus has found it easy to adapt to arid and especially cold conditions. Most of its members are associated with high-altitude lands, forest clearings or high latitude and tundra. ''Erebia'' species are frequent in the Alps, Rocky Mountains, subarctic and even Arctic regions, and the cooler parts of Central Asia. In fact, the North American term for these butterflies is alpines. Palearctic species are collectively known as ringlets or arguses. However, none of these terms is used exclusively for this genus. Taxonomy and systematics The genus ''Erebia'' was erected by Johan Wilhelm Dalman in 1816. As type species, the Arran brown—described as ''Pa ...

Anthoxanthum Odoratum
''Anthoxanthum odoratum'', known as sweet vernal grass, is a short-lived perennial grass that is native to acidic grassland in Eurasia and northern Africa. It is grown as a lawn grass and a house plant, due to its sweet scent, and can also be found on unimproved pastures and meadows. The specific epithet ''odoratum'' is Latin for 'odorous'. Description ''Anthoxanthum odaoratum'' is a short-lived perennial grass that grows in tufts with stems up to tall. The leaves are short and broad, wide, and glabrous to loosely hairy. It flowers in late spring and early summer, i.e. quite early in the season, with flower spikes of long and crowded spikelets of , oblong shaped, which can be quite dark when young. The lower lemmas have projecting awns. The ligules are quite long, up to , blunt, with hairy fringes around the side. The scent is particularly strong when dried, and is due to coumarin, a glycoside, and benzoic acid – it smells like fresh hay with a hint of vanilla. The see ...

Festuca Ovina
''Festuca ovina'', sheep's fescue or sheep fescue, is a species of grass. It is sometimes confused with hard fescue (''Festuca trachyphylla''). General description It is a perennial plant sometimes found in acidic ground, and in mountain pasture, throughout Europe (with the exception of some Mediterranean areas) and eastwards across much of Asia; it has also been introduced to North America. It is one of the defining species of the British NVC community CG2, i.e. ''Festuca ovina'' – ''Avenula pratensis'' grassland, one of the calcicolous grassland communities. However, the species has a wide ecological tolerance in the UK, occurring on both basic and acid soils, as well as old mining sites and spoil heaps that are contaminated with heavy metals. Sheep's fescue is a densely tufted perennial grass. Its greyish-green leaves are short and bristle-like. The panicles are both slightly feathery and a bit one-sided. It flowers from May until June, and is wind-pollinated. It has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poa Nemoralis
''Poa nemoralis'', the wood bluegrass, is a perennial plant in the family Poaceae. The late-growing grass is fairly nutritious for livestock, which feed on it in the autumn, and it is used as a lawn grass for shady situations. Description It forms loose tufts, and is of a more delicate, slender appearance than other meadow grasses. It is slightly creeping. The leaves are narrow, tapering to a point. The ligules are short (0.5 mm). The stem is slender, high. The panicle is slender, loose and branched. The spikelets are few and egg shaped. They have one to five flowers. This grass is in flower from June to August in the Northern Hemisphere. It can produce asexual seeds by means of apomixis and can also reproduce vegetatively. Because of the characteristic leaf#Divisions of the lamina (blade), lamina, similar to a stretched out arm, it is sometimes called "Wegweisergras" (signpost grass) in Germany.

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.Darbyshire, S. J. and L. E.

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] |
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 .

Satyrinae
The Satyrinae, the satyrines or satyrids, commonly known as the browns, are a subfamily of the Nymphalidae (brush-footed butterflies). They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. The true number of the Satyrinae species is estimated to exceed 2,400. Overview They are generally weak fliers and often shun bright sunlight, preferring moist and semishaded habitats. The caterpillars feed chiefly on monocotyledonous plants such as palms, grasses, and bamboos. The Morphinae are sometimes united with this group. The taxonomy and systematics of the subfamily are under heavy revision. Much of the early pioneering work of L. D. Miller has helped significantly by creating some sort of order. '' Dyndirus'' (Capronnier, 1874) is a satyrid ''incertae sedis''. Other than this genus, according to the latest studies on the classification of Nymphalidae, all satyrines have been assigned to one of t ...
