''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 moth is bivoltine, i.e. two generations in May and August. The posterior tarsi with dark fuscous spots.

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 ext ...

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
''Sorbus torminalis'', with common names wild service tree, chequers, and checker tree, is a species of tree in the mountain Fraxinus, ash or rowan genus (''Sorbus'') of the rose family (Rosaceae), that is native to Europe, parts of northern Africa and western Asia. Description It is a medium-sized deciduous tree growing to tall, with a trunk up to in diameter. The Bark (botany), bark is smooth and grayish, but flaky, peeling away in squarish plates to reveal darker brown layers. The leaves are long and broad with a petiole, dark green on both sides, with five to nine acute lobes; the basal pair of lobes are spreading, the rest more forward-pointing and decreasing in size to the leaf apex, and with finely toothed margins; the undersides have small hairs when young, but both sides are smooth and shiny when older; the autumn colour is yellow to red-brown. The flowers are in diameter, with five white petals and 20 creamy-white stamens; they are produced in corymbs diameter in ...

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] |
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.

Mespilus Germanica
''Mespilus germanica'', known as the medlar or common medlar, is a large shrub or small tree in the rose family Rosaceae. The fruit of this tree, also called medlar, has been cultivated since Roman times, is usually available in winter and eaten when bletted. It may be eaten raw and in a range of cooked dishes. When the genus ''Mespilus'' is included in the genus ''Crataegus'', the correct name for this species is ''Crataegus germanica'' (Kuntze). In the southwest of England it historically had a number of vulgar nicknames, such as open-arse and monkey's bottom, due to the appearance of its large calyx. 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cydonia Oblonga
The quince (; ''Cydonia oblonga'') is the sole member of the genus ''Cydonia'' in the Malinae subtribe (which also contains apples and pears, among 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 seldom eaten raw, but are processed into marmalade, jam, paste (known as quince cheese) or alcoholic beverages. The quince tree is also grown as an ornamental plant for its attractive pale pink blossoms and other ornamental qualities. Description The tree grows high and wide. The fruit is long and across. The immature fruit is green with dense grey-white fine hair, most of which rubs off before maturity in late autumn when the fruit changes colour to yellow with hard, strongly perfumed flesh.
