Phyllonorycter Oxyacanthae
''Phyllonorycter oxyacanthae'' is a moth of the family Gracillariidae found in all of Europe except the Balkan Peninsula. It was Species description, described by the German people, German-born Swiss people, Swiss entomologist, Heinrich Frey in 1856. The larvae are known as leaf miners, living inside the leaves of their food plants. Description The wingspan is 6–8 mm. The posterior tarsi with dark fuscous spots. Forewings are golden-brown to dark brown; a white median streak from base to near middle, dark margined above; dorsum narrowly white towards base; four costal and three dorsal white wedge-shaped spots, anteriorly blackish-margined, first costal small, first dorsal long, sometimes interrupted; a blackish apical spot. Hindwings are dark grey. ;Similar species ''Phyllonorycter sorbi'' and ''Phyllonorycter mespilella'' are close relatives and require Sex organ, genitalia examination to tell apart, alternatively collect the pupa from the food plants. ;Ovum Eggs are la ...

Heinrich Frey
Heinrich Frey (June 15, 1822 – January 17, 1890) was a German-born Swiss entomologist who studied Lepidoptera. Biography Heinrich Frey was born on June 15, 1822 in Frankfurt. He attended the gymnasium in Frankfurt 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, 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 extraordinary professorial chair is one created by a university because of an application from an outside organisation ...

Crataegus Chrysocarpa
''Crataegus chrysocarpa'' is a species of hawthorn that is native to much of the continental United States and Canada. Common names fireberry hawthorn and goldenberry hawthorn, as well as the scientific name all refer to the colour of the unripe fruit, although the mature fruit is red and in var. ''vernonensis'' is "deep claret-colored … nearly black when over-ripe". Three varieties ''C. chrysocarpa'' var. ''chrysocarpa'', var. ''piperi'', and var. ''vernonensis'' are recognized.

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Torminalis
''Torminalis'' is a genus of plants in the rose family, Rosaceae. The genus was formerly included within the genus ''Sorbus'' as the Section (biology), section ''Torminaria'', but the simple-leafed species traditionally classified in ''Sorbus'' are now considered to form a separate Monophyly, monophyletic group. It is monotypic, being represented by the single species ''Torminalis glaberrima'', common name, commonly known as wild service tree, chequers, and checker tree. This tree is native to Europe, parts of northern Africa and western Asia. A possible second species in the genus has been identified through DNA analysis, but a new scientific description for it has not yet been written. Description ''Torminalis glaberrima'' is a medium-sized deciduous tree growing to about 30 m (100 ft) tall, with a trunk up to 1.3 m in diameter. The Bark (botany), bark is smooth and grey when young, becoming scaly and flaking away in squarish plates to reveal darker brown layers when about 30 ...

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (, also ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. 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. 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 plant is frost hardy and colonizes disrupted and inacces ...

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'', 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.

Mespilus Germanica
''Mespilus germanica'', known as the medlar or common medlar, is a large shrub or small tree in the rose family Rosaceae. When the genus ''Mespilus'' is included in the genus ''Crataegus'', the correct name for this species is ''Crataegus germanica'' (Carl Linnaeus, L.) Otto Kuntze, Kuntze. The fruit of this tree, also called medlar, has been cultivated since Roman era, Roman times. It is usually available in winter and eaten when Bletting, bletted. It may be consumed raw and in a range of cooked dishes. Description Under ideal circumstances, the deciduous plant grows up to tall. Generally, it is shorter and more shrub-like than tree-like. With a lifespan of 30–60 years, the tree is rather short-lived. Its bark is grayish brown with deep vertical cracks forming rectangular plates that tend to lift off. The wild form of ''M. germanica'' is mostly a thorny, more shrub-like than tree-like plant, which is between high. In the cultivated forms, the thorns are usually reduced or ...

Cydonia Oblonga
The quince (; ''Cydonia oblonga'') is the sole member of the genus ''Cydonia'' in the Malinae subtribe (which contains apples, pears, and other fruits) of the Rosaceae family. It is a deciduous tree that bears hard, aromatic bright golden-yellow pome fruit, similar in appearance to a pear. Ripe quince fruits are hard, tart, and astringent. They are eaten raw or processed into jam, quince cheese, or alcoholic drinks. The quince tree is sometimes grown as an ornamental plant for its attractive pale pink blossoms and as a miniature bonsai plant. In ancient Greece, the word for quince was used ribaldly by poets such as Aristophanes to signify teenage breasts. Description Quinces are shrubs or small trees up to tall and wide. Young twigs are covered in a grey down. The leaves are oval, and are downy on the underside. The solitary flowers, produced in late spring after the leaves, are white or pink.
