Pyrgus Ruralis
''Pyrgus ruralis'', the two-banded checkered skipper, is a species of skipper butterfly (family Hesperiidae). It is found from southern British Columbia and the Rocky Mountains of SW Alberta, with populations south to central California, Nevada, Utah, and Colorado, and one population of an endangered subspecies in southern California, in the mountains east of San Diego. That endangered subspecies is ssp. ''lagunae'', known by the common name Laguna Mountains skipper. The wingspan is 25–29 mm. There is one generation from April to July. The larvae feed on herbaceous plants in the rose family '' Rosaceae'', including ''Potentilla drummondii'', ''Horkelia fusca'', ''Horkelia tenuiloba'' and ''Horkelia bolanderi clevelandii''. Adults feed on flower nectar. Subspecies *''Pyrgus ruralis ruralis'' *''Pyrgus ruralis lagunae ''Pyrgus ruralis lagunae'', the Laguna Mountains skipper, is a butterfly of the family Hesperiidae.

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] |
Skipper (butterfly)
Skippers are a family of the Lepidoptera (moths and butterflies) named the Hesperiidae. Being diurnal, they are generally called butterflies. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea, the butterflies. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly have an absence of wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea.

Laguna Mountains Skipper
''Pyrgus ruralis lagunae'', the Laguna Mountains skipper, is a butterfly of the family Hesperiidae. It is a subspecies of ''Pyrgus ruralis''. Overview The Laguna Mountains skipper is a small, black and white checkered butterfly belonging to the family Hesperiidae. It has a wingspan of about 1 inch (3 cm) and a fast, erratic flight pattern. This endangered butterfly is found only in Southern California, occupying areas of high elevation in the Cleveland National Forest in San Diego, California. Phenotype differences between males and females represented by more white coloration of wings of males compared to that of females. This taxon is one of two subspecies of the rural skipper, ''Pyrgus ruralis''. The other subspecies, ''Pyrgus ruralis ruralis'', occupies a much larger range stretching from British Columbia to Central California. Habitat The Laguna Mountains skipper is endemic to Southern California. It is found mostly in wet montane meadows, reaching altitudes o ...

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 ...

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 immobil ...

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are ''Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), ''Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potentilla Drummondii
''Potentilla drummondii'' is a species of cinquefoil known by the common name Drummond's cinquefoil.

The plant is variable, growing decumbent or erect, small and tufted or up to 60 centimeters tall, hairless to woolly. The leaves are divided into several leaflets, which may be cut into lobes or toothed.

Horkelia Fusca
''Horkelia fusca'' is a species of flowering plant in the rose family known by several common names, including pinewoods horkelia and dusky horkelia. It is native to the western United States from California to Wyoming, where it is generally found in mountain forests and meadows. This perennial herb forms a thick tuft of leaves, each growing erect up to 15 centimeters tall. Each leaf is made up of wedge-shaped or rounded leaflets with toothed or lobed edges. These are often gray-green and somewhat hairy. The brown or reddish hairy stem reaches a maximum height near 60 centimeters and holds an inflorescence of several clusters of flowers. Each flower has small, pointed bractlets beneath larger green, red, or magenta sepals and five white to pinkish petals. The center of the flower has a ring of ten stamens around a bunch of 10 to 20 small pistils. There are several subspecies, including: *''H. f.'' subsp.
