Mitchell's Satyr
''Neonympha mitchellii'' is an endangered species of nymphalid butterfly of the eastern United States. There are two known subspecies:. *''N. m. mitchellii'', the nominate subspecies, commonly called Mitchell's satyr or Mitchell's marsh satyr, is found in Michigan and Indiana. The species is presumably extirpated from former ranges in Ohio (last seen in the 1950s), New Jersey (last seen in 1988), and Wisconsin. *'' N. m. francisci'', commonly called Saint Francis' satyr, is found in a single metapopulation in a 10 × 10 km area of Fort Bragg in North Carolina. Recent discoveries since 1998 of populations in Alabama, Mississippi, and Virginia are being studied for taxonomic classification, and may be grouped with ''N. m. mitchellii'' or be described as new subspecies. All subspecies, including those newly discovered, are federally protected under the Endangered Species Act. Its larvae can feed upon the highly-invasive Japanese stilt grass ''Microstegium vimineum'', so popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

Hermeuptychia Sosybius
''Hermeuptychia sosybius'', the Carolina satyr, is a butterfly of the family Nymphalidae. It is found in the United States from southern New Jersey south along the coast to southern Florida, west to south-eastern Kansas, central Oklahoma and central Texas. It is also found in Mexico and Central America. The wingspan is 32–38 mm. The upperside is brown without markings. The underside is also brown, but with small eyespots rimmed with yellow on both wings. They feed on sap and rotting fruit. Its larvae can feed upon the highly-invasive Japanese stilt grass '' Microstegium vimineum'', so populations of this butterfly are potentially at risk from efforts to remove stilt grass. The endangered Mitchell's Satyr '' Neonympha mitchellii'' is also able to feed upon stilt grass. The larvae also feed on various Poaceae species, including '' Axonopus compressus'', '' Eremochloa ophiuroides'', ''Stenotaphrum secundatum St. Augustine grass (''Stenotaphrum secundatum''), al ...

Eclosion
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosis ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Register
The ''Federal Register'' (FR or sometimes Fed. Reg.) is the official journal of the federal government of the United States that contains government agency rules, proposed rules, and public notices. It is published every weekday, except on federal holidays. The final rules promulgated by a federal agency and published in the ''Federal Register'' are ultimately reorganized by topic or subject matter and codified in the '' Code of Federal Regulations'' (CFR), which is updated annually. The ''Federal Register'' is compiled by the Office of the Federal Register (within the National Archives and Records Administration) and is printed by the Government Publishing Office. There are no copyright restrictions on the ''Federal Register''; as a work of the U.S. government, it is in the public domain. Contents The ''Federal Register'' provides a means for the government to announce to the public changes to government requirements, policies, and guidance. * Proposed new rules and regulat ...

Microstegium Vimineum
''Microstegium vimineum'', commonly known as Japanese stiltgrass, packing grass, or Nepalese browntop, is an annual plant, annual grass that is common in a wide variety of habitats and is well adapted to low light levels. Despite being non-native in the United States, it serves as a host plant for some native satyr butterflies, such as the Carolina satyr ''Hermeuptychia sosybius'' and the endangered Mitchell's satyr ''Neonympha mitchellii''. Owing to its invasive potential, the plant has been put on the European list of invasive alien species. This means the plant can no longer be imported into or traded in the European Union. Distribution It is native in much of South Asia, East Asia, and parts of Southeast Asia, and has since moved to the United States. Description It typically grows to heights between and is capable of rooting at each Node (botany), node. The plant flowers in late summer and produces its seeds in the form of a caryopsis shortly thereafter. It is quite simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.
