Stigmella Aceris
''Stigmella aceris'' is a moth of the family Nepticulidae found in Europe. It was first described by Heinrich Frey in 1857. The moth flies from May to June and again in August depending on the location and has a wingspan of 3.7–4.7 mm. Larvae mine the leaves of its food plant making a narrow corridor usually filling the entire width of the corridor with frass. Eggs are laid on field maple (''Acer campestre ''Acer campestre'', known as the field maple, is a flowering plant species in the family Sapindaceae. It is native to much of continental Europe, Britain, southwest Asia from Turkey to the Caucasus, and north Africa in the Atlas Mountains. It h ...''), Amur maple ( ''A. ginnala''), Norway maple ( ''A. platanoides'') and Tatarian maple ( ''A. tataricum''). There is some debate as to whether the moth mines the leaves of sycamore ( A. pseudoplatanus'') with ''Plant Parasites of Europe'' stating that it is never found on sycamore and ''UKmoths'' stating it is found on ...

Heinrich Frey
Heinrich Frey (June 15, 1822 – January 17, 1890) was a German-born Swiss entomologist who studied Lepidoptera. He was born in Frankfurt am Main, Germany, and died in Zurich, Switzerland. He is not to be confused with the dipterist Richard Karl Hjalmar Frey. Biography Heinrich Frey attended the gymnasium in Frankfurt am Main until he was 16. Here he met Senator Carl Heinrich Georg von Heyden (1793–1866) who introduced him to entomology. He attended the University in Frankfurt am Main, then travelled to Bonn, Berlin, and Göttingen. When he returned to Frankfurt am Main in 1839 von Heyden showed him Philipp Christoph Zeller's ''Attempt at a Classification of the Tineinae'' which had just appeared in Oken's ''Isis''. Until this publication, this group of moths had been hopelessly confused and Frey was impressed by Zeller's orderly arrangement. Returning to Göttingen in 1847 he first became a private tutor, then an “extraordinary” professor at the University. (An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nepticulidae
Nepticulidae is a family of very small moths with a worldwide distribution. They are characterised by eyecaps over the eyes (see also Opostegidae, Bucculatricidae, Lyonetiidae). These pigmy moths or midget moths, as they are commonly known, include the smallest of all living moths, with a wingspan that can be as little as 3 mm in the case of the European pigmy sorrel moth, but more usually 3.5–10 mm. The wings of adult moths are narrow and lanceolate, sometimes with metallic markings, and with the venation very simplified compared to most other moths. The minute larvae usually are leaf miners but some species also mine seeds or bark of trees. Much is known about their host plants. The Pectinivalvinae, characterised by a "pectinifer" on the valve of the male genitalia, are endemic to Australia, where they mine the leaves of the tree families Myrtaceae (Scoble, 1983) or Cunoniaceae ( Eucryphiaceae), and Elaeocarpaceae (Hoare, 2000). This Australian group probably cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...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 . 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 ...

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 ...

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] |
Acer Campestre
''Acer campestre'', known as the field maple, is a flowering plant species in the family Sapindaceae. It is native to much of continental Europe, Britain, southwest Asia from Turkey to the Caucasus, and north Africa in the Atlas Mountains. It has been widely planted, and is introduced outside its native range in Europe and areas of USA and Western Australia with suitable climate. Description It is a deciduous tree reaching tall, with a trunk up to in diameter, with finely fissured, often somewhat corky bark. The shoots are brown, with dark brown winter buds. The leaves are in opposite pairs, long (including the petiole) and broad, with five blunt, rounded lobes with a smooth margin. Usually monoecious, the flowers are produced in spring at the same time as the leaves open, yellow-green, in erect clusters across, and are insect-pollinated. The fruit is a samara with two winged achenes aligned at 180°, each achene is wide, flat, with a wing. The two varieties, not ac ...

Acer Ginnala
''Acer ginnala'', the Amur maple, is a plant species with woody stems native to northeastern Asia from easternmost Mongolia east to Korea and Japan, and north to the Russian Far East in the Amur River valley. It is a small maple with deciduous leaves that is sometimes grown as a garden subject or boulevard tree. Description ''Acer ginnala'' is a deciduous spreading shrub or small tree growing to tall, with a short trunk up to diameter and slender branches. The bark is thin, dull gray-brown, and smooth at first but becoming shallowly fissured on old plants. The leaves are opposite and simple, long and wide, deeply palmately lobed with three or five lobes, of which two small basal lobes (sometimes absent) and three larger apical lobes; the lobes are coarsely and irregularly toothed, and the upper leaf surface glossy. The leaves turn brilliant orange to red in autumn, and are on slender, often pink-tinged, petioles long. The flowers are yellow-green, diameter, produced in ...

Acer Platanoides
''Acer platanoides'', commonly known as the Norway maple, is a species of maple native to eastern and central Europe and western Asia, from Spain east to Russia, north to southern Scandinavia and southeast to northern Iran. It was introduced to North America in the mid-1700s as a shade tree. It is a member of the family Sapindaceae. Description ''Acer platanoides'' is a deciduous tree, growing to tall with a trunk up to in diameter, and a broad, rounded crown. The bark is grey-brown and shallowly grooved. Unlike many other maples, mature trees do not tend to develop a shaggy bark. The shoots are green at first, soon becoming pale brown. The winter buds are shiny red-brown. The leaves are opposite, palmately lobed with five lobes, long and across; the lobes each bear one to three side teeth, and an otherwise smooth margin. The leaf petiole is long, and secretes a milky juice when broken. The autumn colour is usually yellow, occasionally orange-red. The flowers are in ...
