Erebia Medusa Polaris
''Erebia polaris'', the Arctic woodland ringlet, is a butterfly of the family Nymphalidae. It is found in Lapland and boreal Asia. The habitat consists of damp grasslands, but this butterfly also occurs on dry grasslands and in waste places, often where shelter is provided by birches or juniper bushes. Description The Arctic woodland ringlet is a medium-sized butterfly with a wingspan of between . Females tend to be a little larger than males. The upperside of both the forewings and hindwings are dark brown with black eyespots with red margins in a row near the edge. In the male the eyespots are small and do not usually have a white centre except possibly the front one. In the female they may be no bigger but many of them have white centres and they may be more numerous forming a continuous line. The underside of the wings is similar to the upperside. This butterfly can be distinguished from the rather similar Lapland ringlet (''Erebia embla'') and the Arran brown (''Erebia li ...

Arran Brown
''Erebia ligea'', the Arran brown, is a member of the subfamily Satyrinae of the family Nymphalidae. This brown is widespread in south-eastern and northern Europe. It prefers mixed woodlands at low altitudes. It is rarely seen in open areas. This species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae'', and the type locality is Sweden. Description The Arran brown is a medium-sized butterfly with a wingspan of between . Females tend to be a little larger than males. The upperside of both the forewings and hindwings is dark greyish brown with a reddish-orange strip near the margin along which runs a series of black spots. Many of the spots are small but some have white centres. The underside of the forewing is dark brown with a reddish strip with black, white-centred eyespots near the outer edge. The underside of the hindwing is brown, edged with a row of more or less distinct dark coloured eyespots. The basal side of these is close to the cen ...

Butterflies Of Europe
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 fli ...

Insects Of The Arctic
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Festuca Ovina
''Festuca ovina'', sheep's fescue or sheep fescue, is a species of grass. It is sometimes confused with hard fescue (''Festuca trachyphylla''). General description It is a perennial plant sometimes found in acidic ground, and in mountain pasture, throughout Europe (with the exception of some Mediterranean areas) and eastwards across much of Asia; it has also been introduced to North America. It is one of the defining species of the British NVC community CG2, i.e. ''Festuca ovina'' – ''Avenula pratensis'' grassland, one of the calcicolous grassland communities. However, the species has a wide ecological tolerance in the UK, occurring on both basic and acid soils, as well as old mining sites and spoil heaps that are contaminated with heavy metals. Sheep's fescue is a densely tufted perennial grass. Its greyish-green leaves are short and bristle-like. The panicles are both slightly feathery and a bit one-sided. It flowers from May until June, and is wind-pollinated. It has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Ringlet
The Arctic ringlet or Disa alpine (''Erebia disa'') is a member of the subfamily Satyrinae of family Nymphalidae. It is associated with wet muskeg and bogs in subarctic and Arctic climates, and is often found near the tree-line. The larva overwinters twice before undergoing metamorphosis into an adult. It is found in Arctic Europe, Arctic European Russia (Kanin Peninsula), Sajan, Irkutsk, Yakutsk, Yablonoi and Arctic North America.

The Lapland ringlet (''Erebia embla'') is a member of the subfamily Satyrinae of the family Nymphalidae. It is restricted to sunny patches in very damp spruce and pine forests and forested unmanaged peatlands (and sometimes moors). The larva feeds on various grasses and related plants (such as ''Carex ''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' ...'') and winters twice. A dry period in the habitat will result in the decline of the species.
