Speyeria Callippe Callippe
The callippe silverspot butterfly (''Speyeria callippe callippe'') is a federal endangered subspecies in the brush-footed butterfly family Nymphalidae. This is a subspecies. It is a member of the Heliconiinae, the subfamily known as longwings. The adult has a wingspan of just over two inches. The wings are eyecatching with a brown, tan, and black scalloped pattern on their surfaces and orange-brown with characteristic silver spots on the undersides. The wings and abdomen are hairy. The larvae are spiny, dark-colored caterpillars. The larvae are dark colored with many branching sharp spines on their backs. The larvae eat only one species of plant, the yellow pansy, or "Johnny Jump-up" (''Viola pedunculata''). The female adults lay their eggs on the plant or nearby, and the larvae overwinter nearby in a silk pouch. In the spring they feed on the yellow pansy, molt four times, then pupate for two weeks in a nest of leaves which they glue together with silk. The adult lifespan is abou ...

Jean Baptiste Boisduval
Jean Baptiste Alphonse Déchauffour de Boisduval (24 June 1799 – 30 December 1879) was a French lepidopterist, botanist, and physician. He was one of the most celebrated lepidopterists of France, and was the co-founder of the Société entomologique de France. While best known abroad for his work in entomology, he started his career in botany, collecting a great number of French plant specimens and writing broadly on the topic throughout his career, including the textbook ''Flores française'' in 1828. Early in his career, he was interested in Coleoptera and allied himself with both Jean Théodore Lacordaire and Pierre André Latreille. He was the curator of the Pierre Françoise Marie Auguste Dejean collection in Paris and described many species of beetles, as well as butterflies and moths, resulting from the voyages of the ''Astrolabe'', the expedition ship of Jean-François de Galaup, comte de La Pérouse and the '' Coquille'', that of Louis Isidore Duperrey. He lef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Off-road Vehicles
An off-road vehicle (ORV), also known as an off-highway vehicle (OHV), overland vehicle or adventure vehicle, is a type of transportation specifically engineered to navigate unpaved roads and surfaces. These include trails, forest roads, and other low-traction terrains. Off-road vehicles are widely used in various contexts, from recreational activities to practical applications like agriculture and construction. Events such as the annual Dakar Rally, which spans multiple countries and challenges participants with diverse and extreme terrains, have brought significant attention to these vehicles. History One of the earliest modified off-road vehicles was the Kégresse track, a system for modifying cars developed by Adolphe Kégresse while working for Tsar Nicholas II of Russia between 1906 and 1916. The system employed a caterpillar track with a flexible belt instead of interlocking metal segments, which could be fitted to a conventional vehicle, turning it into a half-track su ...

Endangered Fauna Of California
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) IUCN Red List, Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have Environmental law, laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.

Endemic Insects Of The United States
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

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 The Diana fritillary (''Speyeria diana'') is a List of fritillaries (butterflies), fritillary butterfly found in several wooded areas in southern and eastern North America (primarily in the Arkansas River valley, several counties in South Caroli ...''

Giant Panda
The giant panda (''Ailuropoda melanoleuca''), also known as the panda bear or simply panda, is a bear species endemic to China. It is characterised by its white animal coat, coat with black patches around the eyes, ears, legs and shoulders. Its body is rotund; adult individuals weigh and are typically long. It is sexually dimorphic, with males being typically 10 to 20% larger than females. A thumb is visible on its forepaw, which helps in holding bamboo in place for feeding. It has large molar teeth and expanded temporal fossa to meet its dietary requirements. It can digest starch and is mostly herbivorous with a diet consisting almost entirely of bamboo and bamboo shoots. The giant panda lives exclusively in six montane regions in a few Chinese provinces at elevations of up to . It is solitary and gathers only in mating seasons. It relies on olfactory communication to communicate and uses scent marks as chemical cues and on landmarks like rocks or trees. Females rear c ...

Bald Eagle
The bald eagle (''Haliaeetus leucocephalus'') is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle (''Haliaeetus albicilla''), which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting. The bald eagle is an opportunistic feeder that subsists mainly on fish, upon which it swoops down and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to deep, wide, and in weight. Sexual maturity is attained at the age of four to five years. Bald eagles are not bald; the name derives from an older meaning of the word, "white-headed". The adult is mainly brown with a white head ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberian Tiger
The Siberian tiger or Amur tiger is a population of the tiger subspecies ''Panthera tigris tigris'' native to Northeast China, the Russian Far East, and possibly North Korea. It once ranged throughout the Korea, Korean Peninsula, but currently inhabits mainly the Sikhote-Alin mountain region in south-west Primorsky Krai, Primorye Province in the Russian Far East. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade because of intensive conservation movement, conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. This was followed up by a more detailed census which revealed there was a total population of 562 wild Siber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species Act Of 1973
The Endangered Species Act of 1973 (ESA; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting and conserving imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Presidency of Richard Nixon#Environmental policy, Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point wher ...
