Dakota Skipper
''Hesperia dacotae'', the Dakota skipper, is a small to medium-sized North American butterfly. It has a wingspan of approximately one inch and the antennae form a hook. The male's wings are a tawny-orange to brown on the forewings with a prominent mark and dusty yellow on the lower part of the wing. The female wing is a darker brown orange and white spots on the forewing margin. Reproduction The adult Dakota skippers are active for only three weeks in June and July which is their total lifespan. Their eggs, which are laid on the underside of leaves, are hatched in July and the caterpillar larvae feed on native grass until they go dormant in late summer. The caterpillar larvae then winter in shelters very close to the ground. In spring they come out of dormancy in their adult form. They are found in healthy natural tall grass and prairie grass from Minnesota to Saskatchewan. They are now considered extirpated from Illinois and Iowa. The largest most stable population is now found i ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ...

Prairie
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of North ...

ESA Threatened Species
The European Space Agency (ESA) is a 23-member international organization devoted to space exploration. With its headquarters in Paris and a staff of around 2,547 people globally as of 2023, ESA was founded in 1975 in the context of European integration. Its 2025 annual budget was €7.7 billion. The ESA Human and Robotic Exploration programme includes human spaceflight (mainly through participation in the International Space Station programme); as well as the launch and operation of missions to Mars and Moon. Further activities include science missions to Jupiter, Mercury, the Sun, Earth observation, Asteroid impact avoidance and Telecommunications missions, designing launch vehicles; and maintaining Europe's Spaceport, the Guiana Space Centre at Kourou (French Guiana). Further programmes include space safety, satellite navigation, applications and commercialisation. The main European launch vehicle Ariane 6 is operated through Arianespace with ESA sharing in the cost ...

Taxa Named By Carl Linnaeus
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 ...

Butterflies Described In 1758
Butterflies are winged insects from the lepidopteran 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 The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), ..., 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 i ...

Hesperia (butterfly)
''Hesperia'', the branded skippers, is a Holarctic genus in the skippers (Hesperiidae) butterfly family. Most species are endemic to North America, ''Hesperia comma'' is widespread throughout the region. ''H. florinda'' is endemic to temperate eastern Asia. ''H. nabokovi'' is endemic to Hispaniola. Presumably, Johan Christian Fabricius named the genus for Hesperia, one of the Hesperides. Species The following species are recognised in the genus ''Hesperia'': * '' Hesperia assiniboia'' (Lyman, 1892) – Plains skipper * '' Hesperia attalus'' (W. H. Edwards, 1871) – dotted skipper – south United States * '' Hesperia caucasica'' Riabov, 1926 Caucasus * '' Hesperia colorado'' (Scudder, 1874) – western branded skipper * '' Hesperia columbia'' (Scudder, 1872) – Columbian skipper – California to Southwest Oregon * ''Hesperia comma'' (Linnaeus, 1758) – silver-spotted skipper or common branded skipper * '' Hesperia dacotae'' (Skinner, 1911) – Dakota skipper * '' Hesperia ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting and conserving 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 Presidency of Richard Nixon#Environmental policy, 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 wher ...

10th Edition Of Systema Nature
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ...
