Colias Harfordii
''Colias harfordii'', the Harford's sulphur, is a butterfly in the family Pieridae. It is found from the southern California coastal ranges and canyons from Kern County south to San Diego County. The habitat consists of open chaparral and woodland clearings. The wingspan is . The upper surface of the male is rich yellow, with the wing bases not darkened. The cell spot in the front wing is medium-sized and black, often with a white center. The forewing border is wide and the hindwing border is narrower. The cell spot in the hindwing is not noticeable. Females resembles males but the border is less well-defined, in some cases even reduced or lacking. Adults are on wing from February to May and again from June to August in two generations per year. Adults feed on flower nectar of thistles and mints. The larvae feed on the leaves of '' Astragalus douglasii''. The species overwinters in the larval stage.

Henry Edwards (entomologist)
Henry Edwards (27 August 1827 – 9 June 1891), known as "Harry", was an English stage actor, writer and entomologist who gained fame in Australia, San Francisco and New York City for his theatre work. Edwards was drawn to the theatre early in life, and he appeared in amateur productions in London. After sailing to Australia, Edwards appeared professionally in Shakespearean plays and light comedies primarily in Melbourne and Sydney. Throughout his childhood in England and his acting career in Australia, he was greatly interested in collecting insects, and the National Museum of Victoria used the results of his Australian fieldwork as part of the genesis of their collection. In San Francisco, Edwards was a founding member of the Bohemian Club, and a gathering in Edwards' honour was the spark which began the club's traditional summer encampment at the Bohemian Grove.Garnett, 1908, p. 7. As well, Edwards cemented his reputation as a preeminent stage actor and theatre manager. Aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
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] |
Pieridae
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia.DeVries P. J. in Levin S.A. (ed) 2001 The Encyclopaedia of Biodiversity. Academic Press. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family.Carter, David (2000). ''Butterflies and Moths''. The family was created by William John Swainson in 1820. The name "butterfly" is believed to have originated from a member of this family, the brimstone, ''Gonepteryx rhamni'', which was called the "butter-coloured fly" by early British naturalists. The sexes usually differ, often in the pattern or number of the black markings. The larvae (caterpillars) of a few of these species, such ...

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 ...

Astragalus Douglasii
''Astragalus douglasii'' is a species of milkvetch known by the common name Douglas's milkvetch. It is native to California and Baja California, where it can be found in many types of desert, valley, chaparral and woodlands, and montane habitats, usually below elevation. Description ''Astragalus douglasii'' is a bushy perennial herb producing a number of erect or prostrate stems up to a meter long. The abundant leaves are up to 18 centimeters long and are made up of oval-shaped leaflets. The open inflorescence holds up to 30 whitish to pale yellow flowers, each about a centimeter long. The calyx is green with lobes. The fruit is an inflated legume pod up to 6 centimeters long and 3 wide which dries to a thin, papery texture. Varieties There are three varieties of ''Astragalus douglasii'': *''A. d.'' var. ''douglasii'' – limited to California *''A. d.'' var. ''parishii'' (Parish's milkvetch) – found throughout the mountain ranges of Southern California *''A. d.'' va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colias
''Colias'' is a genus of butterflies in the family Pieridae. They are often called clouded yellows; the North American name "sulphurs" is elsewhere used for Coliadinae in general. The closest living relative is the genus ''Zerene'', which is sometimes included in ''Colias''. This genus occurs throughout the Holarctic, including the arctic regions. They are also found in South America, Africa, China and India. Their caterpillars feed on certain Fabaceae, for example vetches (''Vicia''). While most are thus beneficial by keeping weeds at bay, some occasionally become nuisance pests on crops like alfalfa. In some species, the wings of males have brilliant ultraviolet reflection, while those of females do not. Adults of both sexes have various colour forms. Most if not all species of this genus, as usual for Coliadinae, do not sequester toxins or other noxious compounds from their food plants. They are therefore a well-loved prey item of insectivores as compared to ''Pieris'' of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
