Elachista Chrysodesmella
''Elachista chrysodesmella'' is a moth of the family Elachistidae. It is found from Sweden to the Iberian Peninsula, Italy and Romania and from France to Russia and Ukraine. The wingspan is . Adults are on wing from May to June and again from July to August. The larvae feed on ''Brachypodium pinnatum'', '' Brachypodium sylvaticum'', ''Carex humilis'', ''Carex montana'', '' Dactylis glomerata'', '' Holcus'' and '' Poa trivialis''. They mine the leaves of their host plant. The mine starts as a narrow ascending corridor starting at the center of the leaf. Later, the direction reverses and the mine widens. The frass Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the G ... is deposited in the upper part of the mine.

Philipp Christoph Zeller
Philipp Christoph Zeller (8 April 1808 – 27 March 1883) was a German entomologist. Zeller was born at Steinheim an der Murr, Württemberg, two miles from Marbach, the birthplace of Schiller. The family moved to Frankfurt (Oder) where Philipp went to the gymnasium where natural history was not taught. Instead, helped by Alois Metzner, he taught himself entomology mainly by copying books. Copying and hence memorising, developed in response to early financial privation became a lifetime habit. Zeller went next to the University of Berlin where he became a candidat, which is the first degree, obtained after two or three years' study around 1833. The subject was philology. He became an Oberlehrer or senior primary school teacher in Glogau in 1835. Then he became an instructor at the secondary school in Frankfurt (Oder) and in 1860 he was appointed as the senior instructor of the highest technical high school in Meseritz. He resigned this post after leaving in 1869 for Stettin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachypodium Pinnatum
''Brachypodium pinnatum'', the heath false brome or tor-grass, is a species of grass with a widespread distribution in temperate regions of the Northern Hemisphere. It typically grows in calcareous grassland, and reaches tall. The flowerhead is open, with 10 to 15 erect spikelets. Distribution The plant can be found in such US states as California, Massachusetts, and Oregon. Ecology The caterpillars of some Lepidoptera use it as a food plant, e.g. the Essex skipper (''Thymelicus lineola''). It is also one of the most important host grasses for Auchenorrhyncha in central Europe.Nickel, H. (2003).

Elachista
''Elachista'' is a genus of gelechioid moths described by Georg Friedrich Treitschke in 1833. It is the type genus of the grass-miner moth family (Elachistidae). This family is sometimes (in particular in older sources) circumscribed very loosely, including for example the Agonoxenidae and Ethmiidae which seem to be quite distinct among the Gelechioidea, as well as other lineages which are widely held to be closer to '' Oecophora'' than to ''Elachista'' and are thus placed in the concealer moth family Oecophoridae here. These grass-miners are very small moths with the "feathery" hindwings characteristic of their family. They are essentially found worldwide, except in very cold places and on some oceanic islands; as usual for Gelechioidea, they are most common in the Palearctic however. They usually have at least one, sometimes as many as three light bands running from leading to trailing edge of their forewing uppersides. Some species, however, have upper forewings that are mostl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excreme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths ( Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies ( Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to de ...

Poa Trivialis
''Poa trivialis'' (rough bluegrass; ''UK:'' rough-stalked meadow-grass or rough meadow-grass), is a perennial plant regarded in the US as an ornamental plant. It is part of the grass family. Description It is very common in meadows and pastures throughout Britain. Its preferred habitat is moist, sheltered places. Its herbage is plentiful and fairly nutritious, though not as much as ''Poa annua'' or ''Poa pratensis''. It is useful for grazing on heavy and damp soil. It also copes well with the polluted atmosphere of towns and cities. It is in flower from June onwards throughout the summer. It is often considered a weed of golf courses. It is an invasive species in the Great Lakes region and was first sighted in 1843. It has short stolons. The leaves are broad and tapering, and the sheathes are very rough. It has shiny leaves like '' Lolium perenne'' and crested dog's-tail. They have pointed ligules 4–10 mm (3/16 – 3/8 in.) long. Compare to annual meadow grass ''P ...

Dactylis Glomerata
''Dactylis Glomerata'' is the sixth studio album by Swedish doom metal band Candlemass, released in 1998. This was their first album released since their split in 1994. The album was originally destined to be the second release by Candlemass main songwriter Leif Edling's side-project Abstrakt Algebra but, under request from the record label Music for Nations, it was converted in a Candlemass album. There were many musicians involved in the long process of recording, including members of the Abstrakt Algebra's line-up, guitarist Michael Amott of Arch Enemy and Carcass fame and new singer Björn Flodkvist. The music on the album lacks much of the epic doom sound of previous works and embraces a more experimental and progressive approach, with elements of stoner rock and space rock. In 2006, it was reissued by GMR Music as a 2 CD edition. The second disc contains the previously unreleased album ''Abstrakt Algebra II'', from which this album's tracks derived.

Brachypodium Sylvaticum
''Brachypodium sylvaticum'', commonly known as false-brome, slender false brome or wood false brome, is a perennial grass native to Europe, Asia and Africa. It has a broad native range stretching from North Africa to Eurasia. The bunchgrass is most commonly found in forests and woodlands, preferring the shaded canopy, but may grow in open areas. It prefers well drained neutral and calcerous soils, and avoids wet conditions. Description ''Brachypodium sylvaticum'' is a tall tufted perennial bunchgrass that grows up to about a high. The drooping leaf blade of the plant is dark green, or bright-yellow green, flat and up to 12 mm wide with a fringe of hairs surrounding the edge of the leaf. The leaves do not have auricles. The leaf blade is joined to the hollow culm by the leaf sheath. This hairy sheath is open and surrounds the culm. The culm is pilose (long, soft, hairy), and typically has 4 to 5 nodes. The ligules are blunt, long. The grass has drooping narro ... [...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 .
