Phyllonorycter Connexella
''Phyllonorycter connexella'' is a moth of the family Gracillariidae. It is found from Fennoscandia to the Pyrenees and Italy and from France to central Russia and Ukraine.

Philipp Christoph Zeller
Philipp Christoph Zeller (8 April 1808 – 27 March 1883) was a German entomologist. Zeller was born at Steinheim an der Murr, Württemberg, two miles from Marbach, the birthplace of Schiller. The family moved to Frankfurt (Oder) where Philipp went to the gymnasium where natural history was not taught. Instead, helped by Alois Metzner, he taught himself entomology mainly by copying books. Copying and hence memorising, developed in response to early financial privation became a lifetime habit. Zeller went next to the University of Berlin where he became a candidat, which is the first degree, obtained after two or three years' study around 1833. The subject was philology. He became an Oberlehrer or senior primary school teacher in Glogau in 1835. Then he became an instructor at the secondary school in Frankfurt (Oder) and in 1860 he was appointed as the senior instructor of the highest technical high school in Meseritz. He resigned this post after leaving in 1869 for Stettin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus X Canadensis
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar ('' P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The bark on young trees is smooth, white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections ''Populus'' and ''Aigeiros'', the petioles are laterally flattened, so ...

Phyllonorycter
''Phyllonorycter'' is a genus of moths in the family Gracillariidae. Diversity The genus comprises about 400 species, with a worldwide distribution. The vast majority of species are found in the temperate regions, with about 257 species described from the Palaearctic region and 81 from the Nearctic. In the tropics, the genus is species-poor, with 36 species described from Indo-Australia, 13 from the Neotropics and 22 from the Afrotropical region. In 2012, a further 27 species were described from the Afrotropics.

Leaf Miner
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 ...

Salix Purpurea
''Salix purpurea'', the purple willow purpleosier willow or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.Flora Europaea''Salix purpurea''/ref>Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . It is a deciduous shrub growing to 1–3 m (rarely to 5 m) tall, with purple-brown to yellow-brown shoots, turning pale grey on old stems. The leaves are 2–8 cm (rarely to 12 cm) long and 0.3–1 cm (rarely 2 cm) wide; they are dark green above, glaucous green below, and unusually for a willow, are often arranged in opposite pairs rather than alternate. The flowers are small catkins 1.5-4.5 cm long, produced in early spring; they are often purple or red in colour, whence the name of the species (other willows mostly have whitish, yellow or green catkins).

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] |
