Green Hairstreak
The green hairstreak (''Callophrys rubi'') is a small butterfly in the family Lycaenidae. Etymology The genus name '' Callophrys'' is a Greek word meaning "beautiful eyebrows", while the species Latin name ''rubi'' derives from ''Rubus'' (bramble), one of the host plants.

Aston Upthorpe
Aston Upthorpe is a village and civil parish about southeast of Didcot in South Oxfordshire. It was part of Berkshire until the 1974 boundary changes transferred it to Oxfordshire. The motion picture National Lampoon's European Vacation (1985) - Stonehenge Scene was filmed a mile to the south of the village on the ancient downland. The 2011 Census recorded the parish's population as 179. Prehistory Half of the high Blewburton Hill is in the parish. The hill is the site of an Iron Age hill fort that may have been occupied from the 4th century BC to the 1st century BC. Parish church The Church of England parish church of All Saints may date from the second half of the 11th century. However, the only surviving Norman features are one small window in the north wall of the nave and the blocked-up remains of a south doorway. The nave roof may be 14th century and its west wall and Perpendicular Gothic window may be 15th century. The wooden north porch is of uncertain date, poss ...

Ussuri
The Ussuri or Wusuli (russian: Уссури; ) is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860), until it joins the Amur as a tributary to it near Khabarovsk. It is approximately long. The Ussuri drains the Ussuri basin, which covers . Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is , and the average elevation is . Names The Ussuri has been known by many names. In Manchu, it was called the Usuri Ula or Dobi Bira (River of Foxes) and in Mongolian the Üssüri Müren. ''Ussuri'' is Manchu for ''soot-black river''. History * The Ussuri has a reputation for catastrophic floods. It freezes up in November and stays under the ice until April. The river teems with different kinds of fish: graylin ...

Vicia Cracca
''Vicia cracca'' (tufted vetch, cow vetch, bird vetch, blue vetch, boreal vetch), is a species of flowering plant in the pea and bean family Fabaceae. It is native to Europe and Asia. It occurs on other continents as an introduced species, including North America, where it is a common weed. It often occurs in disturbed habitats, including old fields and roadside ditches. Description Cow vetch is in the family Fabaceae and similar to a pea in growth habit with climbing stems growing to 150 cm long, perennial,Parnell, J. and Curtis, T. (2012).

Rubus Idaeus
''Rubus idaeus'' (raspberry, also called red raspberry or occasionally European red raspberry to distinguish it from other raspberry species) is a red-fruited species of ''Rubus'' native to Europe and northern Asia and commonly cultivated in other temperate regions. Taxonomy A closely related plant in North America, sometimes regarded as the variety ''Rubus idaeus'' var. ''strigosus'', is more commonly treated as a distinct species, ''Rubus strigosus'' (American red raspberry), as is done here. Red-fruited cultivated raspberries, even in North America, are generally ''Rubus idaeus'' or horticultural derivatives of hybrids of ''R. idaeus'' and ''R. strigosus;'' these plants are all addressed in the present article. Description Plants of ''Rubus idaeus'' are generally perennials, which bear biennial stems ("canes") from a perennial root system. In its first year, a new, unbranched stem (" primocane") grows vigorously to its full height of 1.5–2.5 m (5.0–8.3 feet), bearing large ...

Betula
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccinium Myrtillus
''Vaccinium myrtillus'' or European blueberry is a holarctic species of shrub with edible fruit of blue color, known by the common names bilberry, blaeberry, wimberry, and whortleberry. It is more precisely called common bilberry or blue whortleberry to distinguish it from other ''Vaccinium'' relatives. Description ''Vaccinium myrtillus'' is a small deciduous shrub that grows tall. It has light green leaves that turn red in autumn and are simple and alternate in arrangement. Leaves are long and ovate to lanceolate or broadly elliptic in shape. Common names Regional names include blaeberry (Scotland), urts or hurts (Cornwall and Devon), hurtleberry, citing Wiersema, J. H. & B.

Univoltine
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callophrys Rubi Egg
The genus ''Callophrys'' consists of butterflies in the family Lycaenidae. It is apparently not monophyletic, but which of the taxa currently considered junior synonyms of ''Callophrys'' are valid genera remains to be determined. The Asian and European members of this genus and some North American species are commonly known as green hairstreaks, and the North American species in the subgenus ''Incisalia'' are called elfins. Species Listed alphabetically within groups. Subgenus ''Callophrys'' Billberg, 1820: * '' Callophrys affinis'' (W. H. Edwards, 1862) – western green hairstreak, immaculate green hairstreak * ''Callophrys amphichloros'' (Cabeau, 1923) * ''Callophrys androflavus'' (Capuse, 1963) * ''Callophrys armeniaca'' Zhdanko, 1998 * '' Callophrys apama'' (W.

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diffraction Grating
In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance between adjacent diffracting elements (e.g., parallel slits for a transmission grating) on the grating, and the wavelength of the incident light. The grating acts as a dispersive element. Because of this, diffraction gratings are commonly used in monochromators and spectrometers, but other applications are also possible such as optical encoders for high precision motion control and wavefront measurement. For typical applications, a reflective grating has ridges or ''rulings'' on its surface while a transmissive grating has transmissive or hollow slits on its surface. Such a grating ...
