Boloria Polaris
''Boloria polaris'', the Polaris fritillary, is a butterfly of the family Nymphalidae. It is found in northernmost Scandinavia, North America (in northeastern Alaska and northern Canada) and in Greenland. It is also found in northeastern Russia and across the Palearctic to Chukotka. It is one of only six butterfly species found on Canada's Ellesmere Island. Description The wingspan is 32–38 mm. A. polaris Bsd. (71e). Similar to the preceding species freija''">Boloria_freija.html" ;"title="''Boloria freija">freija'' but more variable, the hindwing beneath more variegated, the black median band of the forewing above heavy, deep black, deeply sinuous proximally. In the marginal area regular rows of submarginal spots. The forewing beneath almost as distinctly marked with black as above, but paler. On the hindwing beneath the ground is marked with mother-of-pearl in the basal area and the narrow band which separates the central from the marginal area bears silvery teeth. ...

Adalbert Seitz
Friedrich Joseph Adalbert Seitz, (24 February 1860 in Mainz – 5 March 1938 in Darmstadt) was a German physician and entomologist who specialised in Lepidoptera. He was a director of the Frankfurt zoo from 1893 to 1908 and is best known for editing the multivolume reference on the butterflies and larger moths of the world ''Die Gross-Schmetterlinge der Erde'' which continued after his death. Biography Seitz was born in Mainz and went to school in Aschaffenburg, Darmstadt and Bensheim. He studied medicine from 1880 to 1885 and then zoology at Giessen. His doctorate was on the protective devices of animals. He worked as an assistant in the maternity hospital of the University of Giessen and then worked as a ship's doctor from 1887, travelling to Australia, South America and Asia. He began to collect butterflies on these travels. In 1891 he habilitated in zoology with a thesis on the biology of butterflies from the University of Giessen. In 1893 he took up a position as a director ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ledum
''Ledum'' was a genus in the family Ericaceae, including 8 species of evergreen shrubs native to cool temperate and subarctic regions of the Northern Hemisphere and commonly known as Labrador tea. It is now recognised as a subsection of section Rhododendron, subgenus ''Rhododendron'', of the genus ''Rhododendron''. Description ''Ledum'' species often grow together with poisonous plants such as bog-laurel and bog-rosemary, but certain species (e.g. '' L. groenlandicum'' and '' L. palustre'') are easily distinguished by the distinctive rust coloured fuzz on the bottom of leaves. Taxonomy Reclassification into Rhododendron Recent genetic evidence has shown that the species previously treated in this genus are correctly placed in the genus ''Rhododendron'', where they are now treated as ''Rhododendron'' subsect. ''Ledum''. Because some of the species names used in ''Ledum'' could not be used in ''Rhododendron'' (the names already having been used for other species already in this ...

Butterflies Of Asia
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it fli ...

Boloria
''Boloria'' is a brush-footed butterfly (Nymphalidae) genus. ''Clossiana'' is usually included with it nowadays, though some authors still consider it distinct and it seems to warrant recognition as a subgenus at least. Species Listed alphabetically:Jim P.

Subarctic
The subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic, north of humid continental regions and covering much of Alaska, Canada, Iceland, the north of Scandinavia, Siberia, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is usually low, and vegetation is characteristic of the taiga. Daylight at these latitudes is quite extreme between summer and winter due to its high latitude. Near the summer solstice for instance, subarctic regions can experience an all-night period of either civil, nautical, or astronomical twilight (or in the northern reaches full daylight), but without true night, since the sun never dips more than 18 degrees below the horizon. Noctilucent clouds are best observed within this range of latitude. Climate and soils Subarctic temperatures are above for at least one and at most three months of the year. Precipitation tends to be low du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrangel Island
Wrangel Island ( rus, О́стров Вра́нгеля, r=Ostrov Vrangelya, p=ˈostrəf ˈvrangʲɪlʲə; ckt, Умӄиԓир, translit=Umqiḷir) is an island of the Chukotka Autonomous Okrug, Russia. It is the 91st largest island in the world and roughly the size of Crete. Located in the Arctic Ocean between the Chukchi Sea and East Siberian Sea, the island lies astride the 180th meridian. The International Date Line is therefore displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland, to keep the island on the same day as the rest of Russia. The closest land to Wrangel Island is the tiny and rocky Herald Island located to the east.Kosko, M.K., M.P. Cecile, J.C. Harrison, V.G. Ganelin, N.V., Khandoshko, and B.G.

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...

Vaccinium
''Vaccinium'' is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other ericaceous plants, they are generally restricted to acidic soils. Description The plant structure varies between species: some trail along the ground, some are dwarf shrubs, and some are larger shrubs perhaps tall. Some tropical species are epiphytic. Stems are usually woody. Flowers are epigynous with fused petals, and have long styles that protrude from their bell-shaped corollas. Stamens have anthers with extended tube-like structures called "awns" through which pollen falls when mature. Inflorescences can be axillary or terminal. The fruit develops from an inferior ovary, and is a four- or five-parted berry; it is usually brightly coloured, often being red or bluish wi ...
