Two-banded Checkered Skipper
''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 lef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horkelia Tenuiloba
''Potentilla micheneri'' is a species of flowering plant in the rose family. It is known by the common names Santa Rosa oceanspray, Santa Rosa horkelia and thin-lobed horkelia and is endemic to California, where it is known only from the coastal hills and mountains north of the San Francisco Bay Area. It is a plant of chaparral habitat. Description ''Potentilla micheneri'' is a perennial herb producing a low mat of hairy, glandular green foliage around a woody base. The leaves are cylindrical or somewhat flat, often tapering to a point, and each is made up of several densely packed pairs of hairy leaflets. The inflorescence is an array of flowers atop an erect stalk, each flower made up of five pointed green sepals and five white petals. At the center of the flower is a cone of stamens tipped with reddish anthers around many pistils Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop in ...

Taxa Named By Jean Baptiste Boisduval
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Described In 1852
Butterflies are winged insects from the lepidopteran Superfamily (taxonomy), superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage Biological life cycle, life cycle, and like other Holometabola, holometabolous 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 out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrgus
''Pyrgus'' is a genus in the skippers butterfly family, Hesperiidae, known as the grizzled skippers. The name "checkered" or "chequered skipper" may also be applied to some species, but also refers to species in the genera '' Burnsius'' and '' Carterocephalus''. They occur in the Holarctic with an additional group of species extending to the Neotropic. In 2019, most of the species of ''Pyrgus'' found in the North, Central, or South America were moved to the genera '' Burnsius'', '' Chirgus'', and '' Heliopetes''.

Skipper (butterfly)
Skippers are a group of butterflies placed in the family Hesperiidae within the order Lepidoptera (moths and butterflies). They were previously placed in a separate superfamily, Hesperioidea, but have since been placed 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 lack 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. The third and rather small butterfly superfamily is the moth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potentilla Drummondii
''Potentilla drummondii'' is a species of flowering plant, known by the common name Drummond's cinquefoil, in the family ''Rosaceae''. It is native to North America from Alaska to California, where it grows in many types of moist habitat. It is perhaps better described as a species complex containing many intergrading subspecies that readily hybridize with other ''Potentilla'' species. 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. The inflorescence In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches.

Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family 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, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.
