Callippe Silverspot Butterfly
The callippe silverspot butterfly (''Speyeria callippe callippe'') is a federal endangered species 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 about t ...

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 left Paris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sears Point
Sears Point is a prominent landform that juts into the San Pablo Bay in Sonoma County, California, United States.

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 and invasive species. The International Union for Conservation of Nature (IUCN) 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 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. Multiple factors are considered when assessing the sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of California
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 coro ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Off-road Vehicles
An off-road vehicle, sometimes referred to as an overland or adventure vehicle, is considered to be any type of vehicle which is capable of off-roading, driving on and off Pavement (material), paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension (vehicle), suspension, or even caterpillar tracks. Other vehicles that do not travel on public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, Crane (machine), cranes, backhoes, bulldozers, and golf carts. Off-road vehicles have an enthusiastic following because of their versatility. Several types of motorsports involve racing off-road vehicles. The most common use of these vehicles is for tourism, sightseeing in areas distant from the Pavement (material), pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces. Off-road vehicles ...
