Phratora Vitellinae
''Phratora vitellinae'', the brassy leaf beetle, formerly ''Phyllodecta vitellinae'', is a beetle of the family Chrysomelidae found in Europe and Asia. It feeds on ''Populus'' and ''Salix'' species. The evolution of its host plant preferences and the mechanism by which it uses host plant chemicals to make a larval defensive secretion have been the subject of intense study by research groups in Europe and the Nordic countries. Description ''Phratora vitellinae'' adults range from 3.5–5.2 mm long. The opaque forewings (elytra) show longitudinal rows of clearly visible dots. Adults typically show metallic blue, green, or bronze colors. Adults show copper or purple colors at high elevations or in Arctic regions. One way to distinguish among adult ''Phratora'' beetles co-occurring on the same host plant is to gently squeeze the abdomen of females until the morphology of the genitalia can be observed from the ventral side. ''Phratora vitellinae'' females possess a wide smooth s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasyrphus Nigritarsus Eating Phratora Vitellinae
''Parasyrphus'' is a genus of hover fly found in the holarctic area of the world including species like '' Parasyrphus tarsatus'' located in some very northern areas. Very few of the 31 identified species have known larvae. Of the known larvae most are predators of tree aphids with one , ''Parasyrphus nigritarsis'', that feed on beetle eggs and larvae. Description For terminology se Thompson glossary of taxonomic termsbr> Species of this genus are small to medium sized , sturdy, usually with posteriorly rounded yellow spots or straight or posteriorly emarginate yellow bands on the oval abdomen, rarely with yellow abdominal markings reduced or absent. The abdomen is not marginate. The anterior anepisternum with short to moderately long erect hairs, at least posterodorsally. The hind coxa have tufts of hairs at the posteromedial apical angle. The eyes may be either bare or haired. The face usually has a promient tubercle. It is usually yellow or with distinct black median stripe ...

Populus Nigra
''Populus nigra'', the black poplar, is a species of cottonwood poplar, the type species of section ''Aigeiros'' of the genus ''Populus'', native to Europe, southwest and central Asia, and northwest Africa.Flora Europaea''Populus nigra''/ref> Description Black poplars are medium- to large-sized deciduous trees, reaching 20–30 m, and rarely 40 m tall. Their leaves are diamond-shaped to triangular, 5–8 cm long and 6–8 cm broad, and green on both surfaces.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins. . Normally, their trunks achieve up to 1.5 m in diameter, but some unusual individual trees in France have grown old enough to have much larger trunks – more than 3 metres DBH (Diameter at Breast Height). The species is dioecious (male and female flowers are on different plants), with flowers in catkins and pollination achieved by the wind. The black poplar grows in low-lying areas of moist ground. Like most other pioneer species, the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus Balsamifera
''Populus balsamifera'', commonly called balsam poplar, bam, bamtree, eastern balsam-poplar, hackmatack, tacamahac poplar, tacamahaca, is a tree species in the balsam poplar species group in the poplar genus, '' Populus.'' The genus name ''Populus'' is from the Latin for poplar, and the specific epithet ''balsamifera'' from Latin for "balsam-bearing". ''Populus balsamifera'' is the northernmost North American hardwood, growing transcontinentally on boreal and montane upland and flood plain sites, and attaining its best development on flood plains. It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found. The tree is known for its strong, sweet fragrance, which emanates from its sticky, resinous buds. The smell has been compared to that of the balsam fir tree. Taxonomy The black cottonwood, ''Populus trichocarpa'', is sometimes considered a subspecies of ''P. balsamifera'' and may lend its common name to this species, a ...

Salix Euxina
''Salix euxina'', the eastern crack-willow, is a species of flowering plant in the willow family Salicaceae, native from Turkey to the Caucasus. It was first described by I. V. Belyaeva in 2009. It is one of the parents of the common crack-willow, ''Salix'' × ''fragilis''. Description ''Salix euxina'' is a tree which can reach 15–20 m high with a trunk diameter of up to 1 m. It has a wide crown, and old trees develop deeply fissured bark on their trunks. The olive green branchlets are hairless (glabrous) and very brittle at the base, so that branches easily break off. These are able to root and propagate the species. The leaves are pale green and glabrous. They have stomata only on the undersurface. The catkins are relatively thick with somewhat densely clustered flowers. ''Salix'' × ''fragilis'', the hybrid between ''Salix euxina'' and ''Salix alba'', has hairs on its branches and branchlets, stomata on both surfaces of its leaves, and slender, more ...

Salix Eleagnos
''Salix eleagnos'' the bitter willow, olive willow, hoary willow, rosemary willow, or elaeagnus willow, is a species of flowering plant in the family Salicaceae, native to central and southern Europe and south west Asia. Growing to tall by broad, it is an erect bushy deciduous shrub with narrow grey-green leaves up to long, which turn yellow in autumn (fall). The green catkins, long, appear with the leaves in spring, male catkins having yellow anthers. Like all willows, the species is dioecious. The specific epithet ''eleagnos'' is frequently spelt ''elaeagnos'' (Elaeagnus, silverberry or oleaster), though the original spelling has been accepted as a correct Greek form. ''Salix eleagnos'' subsp. ''angustifolia'' has gained the Royal Horticultural Society The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.

Salix Pentandra
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
