Speyeria Adiaste
''Speyeria adiaste'', the unsilvered fritillary or adiaste fritillary, is a species of butterfly of the family Nymphalidae. It is found in California north to San Mateo County and east to north Los Angeles County and Kern County. The wingspan is 50–61 mm. Adults feed on flower nectar. The larvae feed on '' Viola'' species, including '' Viola quercetorum''.

William Henry Edwards
William Henry Edwards (March 15, 1822 – April 2, 1909) was an American businessman and entomologist. He was an industrial pioneer in the coalfields of West Virginia, opening some of the earliest mines in the southern part of the state. He was also a prominent naturalist specializing in the study of butterflies. He wrote ''The Butterflies of North America'', a three-volume treatise that is highly regarded for its scholarship and the quality of its illustrations. Biography Edwards was born in Hunter, New York, a village that had been founded by his family just five years earlier and originally called Edwardsville. The son of William W. Edwards and Helen Ann (Mann) Edwards, he came from a prominent and successful American family. His father was a businessman involved in banking, insurance and European imports. His grandfather was Colonel William Edwards, founder of the family tannery business and inventor of several devices used in the manufacture of leather goods. His great-great ...

Slightly larger than a violin, it has a lower and deeper sound. Since the 18th century, it has been the middle or alto voice of the violin family, between the violin (which is tuned a perfect fifth above) and the cello (which is tuned an octave below). The strings from low to high are typically tuned to C3, G3, D4, and A4. In the past, the viola varied in size and style, as did its names. The word viola originates from the Italian language. The Italians often used the term viola da braccio meaning literally: 'of the arm'. "Brazzo" was another Italian word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Described In 1864
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 f ...

Speyeria
''Speyeria'', commonly known as greater fritillaries, is a genus of butterflies in the family Nymphalidae commonly found in North America, Europe, and Asia. Some authors used to consider this taxon a subgenus of '' Argynnis'', but it has been reestablished as a separate genus in 2017. Species The genus has 3 species in Eurasia (these were formerly known as genus ''Mesoacidalia'', now a synonym of ''Speyeria''): *''Speyeria aglaja'' (Linnaeus, 1758) – Dark green fritillary *''Speyeria alexandra'' (Ménétriés, 1832) *''Speyeria clara'' (Blanchard, 844 and 16 species in North America: *''Speyeria diana'' (Cramer, 777 – Diana fritillary *''Speyeria cybele'' (Fabricius, 1775) – great spangled fritillary *'' Speyeria aphrodite'' (Fabricius, 1787) – Aphrodite fritillary *''Speyeria idalia'' (Drury, 773 – regal fritillary *''Speyeria nokomis'' (Edwards, 1862) – Nokomis fritillary *''Speyeria edwardsii'' (Reakirt, 1866) – Edward's fritillary *''Speyeria coronis'' ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds ( taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Viola (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and f ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design an ...
