Titian Peale
Titian Ramsay Peale (November 2, 1799 – March 13, 1885) was an American artist, naturalist, and explorer from Philadelphia, Pennsylvania. He was a scientific illustrator whose paintings and drawings of wildlife are known for their beauty and accuracy. Peale was a member of several high-profile scientific expeditions. In 1819–1820, he and Thomas Say accompanied Stephen Harriman Long on an expedition to the Rocky Mountains. He was also a member of the United States Exploring Expedition (1838–1842). Starting around 1855 Peale became an enthusiastic amateur photographer. Many of his photographs featured buildings and landscapes in and around Washington D.C. He joined a local club with other amateur photographers and participated in field trips, photo exchanges and contests. By the end of the Civil War, his interest in photography waned and he only occasionally took pictures.

Johann Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospital. ...

Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

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 and anima ...

Carex Bigelowii
''Carex bigelowii'' is a species of sedge known by the common names Bigelow's sedge, Gwanmo sedge, and stiff sedge. It has an Arctic–alpine distribution in Eurasia and North America, and grows up to tall in a variety of habitats. Distribution ''Carex bigelowii'' has a circumpolar or circumboreal distribution, occurring throughout the northern latitudes of the Northern Hemisphere. It is present in Europe, Asia and North America, where it occurs from Alaska to Greenland, and in alpine climates as far south as Utah and Colorado. Description ''Carex bigelowii'' produces 3-angled stems up to tall, growing in a tuft or singly. The leaves are stiff and dark green, and the leaves of previous seasons may remain on the plant. The inflorescence is accompanied by a short bract. The inflorescence has 1–3 black pistillate spikes under 1–2 staminate spikes. The plant usually reproduces vegetatively, sprouting tillers from its rhizome. It also spreads via stolons. It has a thick roo ...

Carex Rupestris
''Carex rupestris'', called the curly sedge and rock sedge (names it shares with other members of its genus), is a species of flowering plant in the family Cyperaceae, native to temperate and subarctic North America, Greenland, Iceland, Europe, and Asia. It prefers to grow on rocky ledges. Subtaxa The following subspecies are currently accepted: *''Carex rupestris'' subsp. ''altimontana'' *''Carex rupestris'' subsp.

Butterflies Described In 1775
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), 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 Holometabolism, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oeneis
''Oeneis'' (the Arctics or graylings) is a butterfly genus of the Satyrinae. All but one of its members are Arctic, sub-Arctic or high-altitude alpine in distribution. Some of the members of the genus are among the butterflies that can get along in the harshest climates of any butterflies. Four species in Europe, more are found in Arctic Russia, Siberia, Mongolia, Arctic North America and the Rocky Mountains. Curiously, there are no observations from Greenland. The development of most species takes two years. Species Listed alphabetically within groups: The ''jutta'' species group: *'' Oeneis fulla'' (Eversmann, 1851) *'' Oeneis jutta'' (Hübner, 1805–1806) – Baltic grayling or Jutta Arctic *'' Oeneis magna'' (Graeser, 1888) *''Oeneis melissa'' (Fabricius, 1775) – Melissa Arctic *'' Oeneis tunga'' (Staudinger, 1894) The ''norna'' species group: *'' Oeneis actaeoides'' (Lukhtanov, 1989) *'' Oeneis glacialis'' (Moll, 1785) – Alpine grayling *'' Oeneis norna'' (Thunberg, ...

Insects Of The Arctic
Insects (from Latin ') are pancrustacean Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of Extant taxon, extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all Natural environment, environments, although only a small number of species reside in the oceans, which are dominated by ...
