Xerces Blue
The Xerces blue (''Glaucopsyche xerces'') is a recently extinct species of butterfly in the gossamer-winged butterfly family, Lycaenidae. The species lived in coastal sand dunes of the Sunset District of the San Francisco Peninsula in California. The Xerces blue is believed to be the first American butterfly species to become extinct due to loss of habitat caused by urban development. The last Xerces blue was seen in 1941 or 1943 on land that is now part of the Golden Gate National Recreation Area. Name The specific name derives from the French spelling of "Xerxes", the Greek name of the Persian kings Xerxes I and Xerxes II of the fifth century BC. An endangered invertebrate conservation group known as the Xerces Society is named after the Xerces blue. Taxonomy Genetic analysis of museum specimens published in 2021 confirmed that the Xerces blue represented a distinct species within the genus '' Glaucopsyche'', with its closest relatives being '' Glaucopsyche australis'' ''a ...

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] |
De-extinction
De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an Extinction, extinct organism. There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered. Similar techniques have been applied to certain endangered species, in hopes to boost their genetic diversity. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues. Methods Cloning Cloning is a commonly suggested method for the potential restoration of an extinct species. It can be done by extracting the nucleus from a preserved cell from the extinct species and swapping it into an egg, without a nucleus, of that species' nearest living relative. The egg can ...

Palos Verdes Blue
The Palos Verdes blue (''Glaucopsyche lygdamus palosverdesensis'') is a small endangered butterfly native to the Palos Verdes Peninsula in southwest Los Angeles County, California, United States. As its distribution has been proven to be limited to one single site, it has one of the best claims to being the world's rarest butterfly. Overview The Palos Verdes blue (''G. l. palosverdesensis'') is a localized subspecies of the silvery blue ('' G. lygdamus''), which ranges over much of North America. It was described in 1977, shortly before it became one of the second groups of butterflies to be listed under the US Endangered Species Act in 1980. It is distinguished from other subspecies of ''G. lygdamus'' by its slightly different patterning on the underside of the wing and an earlier flight period. The subspecies was described from the southern slope of the Palos Verdes Peninsula in coastal Los Angeles County. The Palos Verdes blue butterfly was thought to be driven to extinction ...

Bohart Museum Of Entomology
The Bohart Museum of Entomology was founded in 1946 on the campus of the University of California, Davis. The museum is currently the seventh largest insect collection in North America with more than seven million specimens of terrestrial and freshwater arthropods. At least 90% of these holdings are insects. The collection is worldwide in scope with the Western Hemisphere, Indonesia, and Australasia particularly well represented. Role The principal roles of the museum are to support research at the graduate and undergraduate levels, informatics and diagnostics, and educational outreach. Areas of taxonomic specialization include the worldwide insect order Hymenoptera, freshwater non-insect arthropods, and California insect fauna. Professor Emeritus of entomology Richard M. Bohart was the museum's founder and principal contributor. In 1986 the museum was named in his honor.

Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A 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. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. 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 lar ...

Lupinus
''Lupinus'', commonly known as lupin, lupine, or regionally bluebonnet, is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centre of diversity, centres of diversity in North America, North and South America. Smaller centres occur in North Africa and the Mediterranean Basin, Mediterranean. They are widely cultivated, both as a food source and as ornamental plants, but are invasive to some areas. Description The species are mostly herbaceous perennial plants tall, but some are annual plants and a few are bush lupin, shrubs up to tall. An exception is the ''chamis de monte'' (''Lupinus jaimehintonianus'') of Oaxaca in Mexico, which is a tree up to tall. Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States and eastern South America. Th ...
