Bucculatrix Bechsteinella
''Bucculatrix bechsteinella'' is a moth of the family Bucculatricidae. It was described by Johann Matthäus Bechstein and Georg Ludwig Scharfenberg in 1805. It is found in most of Europe, except Greece and Bulgaria. The wingspan is 7–9 mm. The head is pale fuscous, mixed in middle with blackish. Forewings are brownish-whitish, irrorated with dark fuscous; a more or less distinct dark streak along fold from base to near middle, often incomplete; three oblique costal spots between 1/3 and apex, and a median dorsal spot suffusedly dark fuscous: second discal stigma forming a short blackish dash. Hindwings are grey. The larva is dull green, more yellowish above; dorsal line darker; dots yellowish and the head pale brown Adults are on wing from mid-May to mid-August. The larvae feed on ''Amelanchier'', ''Chaenomeles'', ''Cotoneaster'', ''Crataegus douglasii'', ''Crataegus laevigata'', ''Crataegus monogyna'', ''Cydonia oblonga'', ''Malus domestica'', ''Mespilus germanica'', ''Da ...

Johann Matthäus Bechstein
Johann Matthäus Bechstein (11 July 1757 – 23 February 1822) was a German naturalist, forester, ornithologist, entomologist, and herpetologist. In Great Britain, he was known for his treatise on singing birds (''Naturgeschichte der Stubenvögel'', ''Natural History of Cage Birds'', 1795). Biography Bechstein was born in Waltershausen in the district of Gotha in Thuringia. He studied theology for four years at the University of Jena, and spent time hunting and roaming the forests as opportunities permitted. After leaving school, he taught for some years, but gave teaching up to devote himself to outdoor pursuits. In 1795, he founded the school of forestry at Waltershausen, and in 1800, the Duke of Saxe-Meiningen made him the director of the forestry school at Dreissigacker near Meiningen in the neighbouring district of Schmalkalden-Meiningen. After the death of his own son, Bechstein adopted his nephew Ludwig Bechstein. Bechstein was a prolific zoologist and one of the first ...

Malus Domestica
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more ...

Moths Described In 1805
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 establishe ...

Leaf Miners
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 determi ...

Consortium For The Barcode Of Life
The Consortium for the Barcode of Life (CBOL) was an international initiative dedicated to supporting the development of DNA barcoding as a global standard for species identification. CBOL's Secretariat Office is hosted by the National Museum of Natural History, Smithsonian Institution, in Washington, DC. Barcoding was proposed in 2003 by Prof. Paul Hebert of the University of Guelph in Ontario as a way of distinguishing and identifying species with a short standardized gene sequence. Hebert proposed the 658 bases of the Folmer region of the mitochondrial gene cytochrome-C oxidase-1 as the standard barcode region. Hebert is the Director of the Biodiversity Institute of Ontario, the Canadian Centre for DNA Barcoding, and the International Barcode of Life Project (iBOL), all headquartered at the University of Guelph. The Barcode of Life Data Systems (BOLD) is also located at the University of Guelph. CBOL was created in May 2004 with support of the Alfred P. Sloan Foundation, f ...

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 "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (UK: /ˈrəʊən/, US: /ˈroʊən/) and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. The plant is undemanding and frost h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Aria
''Sorbus aria'' ( syn. ''Aria nivea''), the whitebeam or common whitebeam, is a deciduous tree, the type species of the subgenus ''Sorbus'' subg. ''Aria'' of the genus ''Sorbus''. It is native to most of Europe as well as North Africa (Algeria, Morocco, Tunisia) and temperate Asia (Armenia, Georgia). Typically compact and domed, with few upswept branches and almost-white underside of the leaves, it generally favours dry limestone and chalk soils. The hermaphrodite cream-white flowers appear in May, are insect pollinated, and go on to produce scarlet berries, which are often eaten by birds. The cultivars ''S. aria'' 'Lutescens', with very whitish-green early leaves, and ''S. aria'' 'Majestica', with large leaves, have both have gained the Royal Horticultural Society's Award of Garden Merit. The berries are edible when overripe ( bletted). File:Sorbus aria-3420.jpg, Foliage and fruit References aria In music, an aria (Italian: ; plural: ''arie'' , or ''arias'' in commo ...

Pyrus Communis
''Pyrus communis'', the common pear, is a species of pear native plant, native to central and eastern Europe, and western Asia. It is one of the most important fruits of temperate regions, being the species from which most orchard pear cultivars grown in Europe, North America, and Australia have been developed. Two other species of pear, the Nashi pear (''Pyrus pyrifolia'') and the hybrid Chinese white or ya pear (''Pyrus × bretschneideri'', ) are more widely grown in East Asia. Subtaxa The following subspecies are currently accepted: *''Pyrus communis'' subsp. ''caucasica'' – Turkey, Caucasus *''Pyrus communis'' subsp. ''communis'' – Entire range except Caucasus Origin The cultivated Common pear (''P. communis'' subsp. ''communis'') is thought to be descended from two subspecies of wild pears, categorized as Pyrus pyraster, ''P. communis'' subsp.'' pyraster'' (syn. ''P. pyraster'') and ''P. communis'' subsp.

Pyracantha Coccinea
''Pyracantha coccinea'', the scarlet firethorn is the European species of firethorn or red firethorn that has been cultivated in gardens since the late 16th century. The tree has small white flowers. It produces small, bright red berries. Its leaves are slightly toothed and grow opposite to one another. The fruit is bitter and astringent, making it inedible when raw. The fruit can be cooked to make jellies, jams, sauces and marmalade. It ranges from southern Europe to western Asia. It has been introduced to North America and cultivated there as an ornamental plant since the 18th century. In England, since the late 18th century, it has been used to cover unsightly walls. Cultivars * ''Pyracantha coccinea'' 'Kasan'. * ''Pyracantha coccinea'' 'Lalandei'. About 1874, M. Lalande, a nurseryman in Angers Angers (, , ) is a city in western France, about southwest of Paris.
