Pieris Virginiensis
''Pieris virginiensis'', the West Virginia white, is a butterfly found in North America in the Great Lakes states, along the Appalachians from New England to Alabama, and in southern Ontario. They are typically found in moist deciduous forests. Forestry, development, and a highly-invasive species that it confuses with its host plant (Cardamine) are causing this species to decline. Along with the butterfly '' Pieris oleracea'', it is threatened by the invasive weed garlic mustard, ''Alliaria petiolata''. The butterflies, having not evolved to be familiar with the plant, confuse it with their host plants. The offspring laid on garlic mustard do not survive. It has translucent whitish wings of length 4.5–5.5 cm; the hindwing underside has brownish or pale gray scaling along the veins.

Butterfly
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, ...

Alliaria Petiolata
''Alliaria petiolata'', or garlic mustard, is a biennial flowering plant in the mustard family (Brassicaceae). It is native to Europe, western and central Asia, north-western Africa, Morocco, Iberia and the British Isles, north to northern Scandinavia, and east to northern Pakistan and Xinjiang in western China. In the first year of growth, plants form clumps of round, slightly wrinkled leaves, that when crushed smell like garlic. The plants flower in spring of the next year, producing cross shaped white flowers in dense clusters. As the flowering stems bloom they elongate into a spike-like shape. When flowering is complete, plants produce upright fruits that release seeds in mid-summer. Plants are often found growing along the margins of hedges, giving rise to the old British folk name of jack-by-the-hedge. Other common names include: garlic mustard, garlic root, hedge garlic, sauce-alone, jack-in-the-bush, penny hedge and poor man's mustard. The genus name ''Alliaria'', "re ...

Pieris (butterfly)
''Pieris'', the whites or garden whites, is a widespread now almost cosmopolitan genus of butterflies of the family Pieridae. The highest species diversity is in the Palearctic, with a higher diversity in Europe and eastern North America than the similar and closely related ''Pontia''. The females of many ''Pieris'' butterflies are UV reflecting, while the male wings are strongly UV absorbing due to pigments in the scales. Ecology Many species of this genus have caterpillars which feed on cabbage and other members of the Brassicaceae. The chemical basis of this association with a certain plant group has been studied for over 100 years, and is now known to occur via a number of biochemical adaptations to chemicals called glucosinolates in these plants. In contrast to most other insects, ''Pieris'' caterpillars are able to detoxify these chemicals, and have become so specialised that they will not eat any food without glucosinolates. The ''Pieris'' females, in turn, check for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vladimir Nabokov
Vladimir Vladimirovich Nabokov (russian: link=no, Владимир Владимирович Набоков ; 2 July 1977), also known by the pen name Vladimir Sirin (), was a Russian-American novelist, poet, translator, and entomologist. Born in Imperial Russia in 1899, Nabokov wrote his first nine novels in Russian (1926–1938) while living in Berlin, where he met his wife. He achieved international acclaim and prominence after moving to the United States, where he began writing in English. Nabokov became an American citizen in 1945 and lived mostly on the East Coast before returning to Europe in 1961, where he settled in Montreux, Switzerland. From 1948 to 1959, Nabokov was a professor of Russian literature at Cornell University. Nabokov's 1955 novel ''Lolita'' ranked fourth on Modern Library's list of the 100 best 20th-century novels in 2007 and is considered one of the greatest 20th-century works of literature. Nabokov's ''Pale Fire'', published in 1962, was ranked 53 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pale Fire
''Pale Fire'' is a 1962 novel by Vladimir Nabokov. The novel is presented as a 999-line poem titled "Pale Fire", written by the fictional poet John Shade, with a foreword, lengthy commentary and index written by Shade's neighbor and academic colleague, Charles Kinbote. Together these elements form a narrative in which both fictional authors are central characters. Nabokov wrote ''Pale Fire'' in 1960–61, after the success of ''Lolita'' had made him financially independent, allowing him to retire from teaching and return to Europe. It was commenced in Nice and completed in Montreux, Switzerland. ''Pale Fire'' has spawned a wide variety of interpretations and a large body of written criticism, which Finnish literary scholar estimated in 1995 as more than 80 studies. The Nabokov authority Brian Boyd has called it "Nabokov's most perfect novel", and the critic Harold Bloom called it "the surest demonstration of his own genius ... that remarkable tour de force".

Insect Wing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Tho ...

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieris Oleracea
''Pieris oleracea'', or more commonly known as the mustard white, is a butterfly in the family Pieridae native to a large part of Canada and the northeastern United States. The nearly all-white butterfly is often found in wooded areas or open plains. There are two seasonal forms, which make it distinct from other similar species. Because of climate change, populations are moving further north. As indicated by the common name, ''P. oleracea'' adults and larvae primarily feed on plants in the mustard family, ''Brassicaceae''. The species is threatened by the rapid, and monoculture-forming, spread of the invasive species ''Alliaria petiolata'', which is toxic to larvae. Populations of ''P. oleracea'' have been declining.https://etd.ohiolink.edu/!etd.send_file?accession=wright1431882480&disposition=inline It may be that this butterfly is slowly adapting to garlic mustard. However, it may not be a fast enough process to ensure its survival, due to the high level of aggression on the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardamine
''Cardamine'' is a large genus of flowering plants in the mustard family, Brassicaceae, known as bittercresses and toothworts. It contains more than 200 species of annuals and perennials. Species in this genus can be found worldwide, except the Antarctic, in diverse habitats. The name ''Cardamine'' is derived from the Greek ''kardaminē'', water cress, from ''kardamon'', pepper grass. Description The leaves can have different forms, from minute to medium in size. They can be simple, pinnate or bipinnate. They are basal and cauline (growing on the upper part of the stem), with narrow tips. They are rosulate (forming a rosette). The blade margins can be entire, serrate or dentate. The stem internodes lack firmness. The nearly radially symmetrical flowers grow in a racemose many-flowered inflorescence or in corymbs. The white, pink or purple flowers are minute to medium-sized. The petals are longer than the sepals. The fertile flowers are hermaphroditic. Taxonomy The genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
