Hoary Comma (15237227779)
The hoary comma (''Polygonia gracilis'') is a species of butterfly, common in boreal North America from Alaska, across southern Canada to New England and the Maritime Provinces and south to New Mexico from the Rocky Mountains to the Pacific Ocean. The wings have a distinctive ragged edge. Adult butterflies feed on tree sap and nectar from sweet everlasting (''Gnaphalium'') as well as other flowers. Caterpillars feed on shrub leaves including currant (''Ribes''), western azalea (''Rhododendron occidentale'') and mock azalea (''Rhododendron menziesii''). The species survives the winter in the adult stage in diapause In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S.

Augustus Radcliffe Grote
Augustus Radcliffe Grote (February 7, 1841 – September 12, 1903) was a British entomologist who Species description, described over 1,000 species of Lepidoptera, butterflies and moths.Osborn, H. 1937. Fragments of Entomological History. Columbus, OH: Published by the author. He is best known for his work on North American Noctuidae. A number of species were named after him, including the moth ''Horama grotei''. Early life and family Grote was born in Aigburth, a suburb of Liverpool, in 1841. His mother was English people, English, and his maternal grandfather, Augustus Radcliffe, was a partner in the house of Sir Joseph Bailey, 1st Baronet, Sir Joseph Bailey. Grote was a first cousin on his mother's side to Ethel Romanes. Grote's father was born in Gdańsk, Danzig, and his paternal lineage traced back to Dutch philosopher Hugo Grotius. His family name was changed from 'Grohté' to 'Grote' when his father became an English citizen. Augustus Grote came to New York City, New ...

Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous 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, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...

Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal ecosystems are some of the most vulnerable to climate change. Both loss of permafrost, reductions in cold weather and increases in summer heat cause significant changes to ecosystems, displacing cold-adapted species, increasing forest fires, and making ecosystems vulnerable to changing to other ecosystem types. These changes can cause Climate change feedback cycles, where thawing permafrost and changing ecosystems release more greenhouse gas emissions into the atmosphere causing more clima ...

North America
North America is a continent in the Northern Hemisphere, Northern and Western Hemisphere, Western hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the south and west by the Pacific Ocean. The region includes Middle America (Americas), Middle America (comprising the Caribbean, Central America, and Mexico) and Northern America.

Pseudognaphalium Obtusifolium
''Pseudognaphalium obtusifolium'', synonyms including ''Gnaphalium obtusifolium'' and ''Pseudognaphalium saxicola'', is a member of the family Asteraceae. It is found on open dry sandy habitat throughout eastern North America. Common names include old field balsam, rabbit tobacco, sweet everlasting and life everlasting. When crushed, the plant exudes a characteristic maple-syrup scent. Description It is a biennial herb which grows up to one meter tall. In its first year, the plant produces tightly packed rosettes covered in wooly hair. In the second year, the plant produces a tall stem with alternate leaves and yellow peg-shaped flowerheads. These are borne in clusters. The seeds are dispersed by the wind. Its native habitats include dry clearings, fields, and edges of woods. Taxonomy ''Pseudognaphalium obtusifolium'' was first described by Carl Linnaeus in 1753 as ''Gnaphalium obtusifolium''. It was transferred to ''Pseudognaphalium'' in 1981. Populations found in the state of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribes
''Ribes'' () is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere.

Rhododendron Occidentale
''Rhododendron occidentale'', the western azalea or California azalea, is one of two deciduous ''Rhododendron'' species native to western North America (the other is '' Rhododendron albiflorum'').

The flowers are 3.5–5 cm diameter, with five lobes on the corolla; color varies from white to pink, often with a yellow blotch. There is considerable diversity in the form and appearance of this species, with genetic diversity seeming to reach its highest level along the coast in the vicinity of the border between Oregon and California. ...
