''Oeneis uhleri'', or Uhler's Arctic, is a species of butterfly in the family Nymphalidae. The larvae feed on various grasses and sedges, including ''Festuca'', ''Koeleria'' and ''Poa'' species.

Tryon Reakirt
Tryon Reakirt (21 April 1844 – after 1871) was an American businessman and entomologist. He wrote several papers on butterflies and showed great promise in his field. However his career was cut short when financial and legal difficulties forced him to flee the country. Tryon Reakirt was born in Philadelphia on April 21, 1844, the son of John Reakirt and Elizabeth Catherine (Tryon) Reakirt. He attended Central High School of Philadelphia and then joined his father in the family business, the import and distribution of pharmaceuticals. In 1868 he invested in a new business, the Delaware Lead Works which manufactured white lead and other lead products. Reakirt joined the American Entomological Society of Philadelphia in 1863 at the age of nineteen. He became well known for his studies of the butterflies of the American tropics and the Asia Pacific region. In his career as an entomologist, Reakirt described many butterflies for the first time; for example, Reakirt described the '' C ...

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.

Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus ''Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Koeleria
''Koeleria'' is a common and widespread genus of plants in the grass family, found on all continents except Antarctica and on various oceanic islands. It includes species known generally as Junegrasses. The genus was named after German botanist Georg Ludwig Koeler (1765–1807). ;Species *'' Koeleria altaica'' – Siberia, China, Kazakhstan, Mongolia *''Koeleria argentea'' – China, Mongolia, Central Asia, Afghanistan, Pakistan, Himalayas *''Koeleria asiatica'' – Russia, China incl Tibet, Mongolia, Alaska, Yukon, Northwest Territories *''Koeleria askoldensis'' – Primorye region of Russia incl Askold Island *'' Koeleria besseri'' – Europe from the Czech Republic to central European Russia *''Koeleria biebersteinii'' – Crimea *''Koeleria boliviensis'' – Bolivia *''Koeleria brevis'' – Ukraine, Russia, Caucasus, Turkey *'' Koeleria calderonii'' – Argentina ( Mendoza) *''Koeleria capensis'' – Yemen, Africa from Ethiopia + Cameroon to Cape Province *''Koeleria carol ...

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 ...

Butterflies Described In 1866
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large 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 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, and after its wings have expanded and dried, it flie ...

Oeneis
''Oeneis'' (the Arctics or graylings) is a butterfly genus of the Satyrinae. All but one of its members are Arctic, sub-Arctic or high-altitude alpine in distribution. Some of the members of the genus are among the butterflies that can get along in the harshest climates of any butterflies. Four species in Europe, more are found in Arctic Russia, Siberia, Mongolia, Arctic North America and the Rocky Mountains. Curiously, there are no observations from Greenland. The development of most species takes two years.
