Lethina
The Satyrini is one of the tribe (biology), tribes of the subfamily Satyrinae. It includes about 2200 species and is therefore the largest tribe in the subfamily which comprises 2500 species. Distribution Satyrini butterflies have a Cosmopolitan distribution, worldwide distribution, but the distribution pattern differs between subtribe, subtribes. Some subtribes are almost restricted to a single biogeographic region, such as the Pronophilina, which is found only in Andean cloud forests from Venezuela to Bolivia. Biology The Larval food plants of Lepidoptera, larval food plants of many species in this tribe are grasses, i.e. Poaceae. It is considered that the Satyrini diversified at about the same time as the grasses did, and that the Evolutionary radiation, radiation of the tribe is therefore closely related to the evolution of the grasses. In contrast, the tribe has a few genera which show uncommon feeding preferences. Three genera, ''Euptychia'', ''Ragadia'' and ''Acrophta ...

Satyrus Actaea
''Satyrus actaea'', the black satyr, is a butterfly of the family Nymphalidae. It is found in South-Western Europe, Asia Minor, Syria, Iran and Baluchistan (Pakistan), Baluchistan (SW Pakistan). The length of the forewings is 24 to 28 mm. Upperside of male black-brown, with a dark sheen in live specimens: the 2 ocelli of the forewing mostly represented only by the small bluish white pupils. In old specimens, with the ground-colour faded, the pupil is bordered with deep black. Between the ocelli of the forewing sometimes 2 minute white dots. The number of the ocelli may be enlarged or diminished as in all ''Satyrus'', e. g. ''merula'' Schultz, ''ornata'' Schultz. In the female the distal band is indicated by a paler, sometimes yellowish brown tint, and the ocelli are considerably larger than in the male. Underside different in the various forms, with a distinctly defined distal ban, a dark dentate line in the cell and across the hindwing, and a somewhat irregular submarginal l ...

Andean
The Andes, Andes Mountains or Andean Mountains (; ) are the List of mountain ranges#Mountain ranges by length, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18th parallel south, 18°S – 20th parallel south, 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto and La Paz. The Altiplano, Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major di ...

Pronophilina
Pronophilina is a Neotropical subtribe of butterflies of the subfamily Satyrinae. They are a species-rich group with highest diversity in the tropical and subtropical mountains, especially the Andes. Before 1970, they were poorly studied, but recent interest has resulted in high rates of species description from previously unexplored mountain ranges. However, there is still a lack of knowledge on their biology and ecology. Their relationship to other groups of Satyrine butterflies and their complex patterns of speciation within and among mountain ranges have led to several biogeographic discussions. Systematics and taxonomy Traditionally the name Pronophilini (or Pronophilidi) was used to describe a tribe of Neotropical satyrines, but modern arrangement place them as a subtribe within the tribe Satyrini of the Satyrinae.Lamas, G. 2004 ''Atlas of Neotropical Lepidoptera. CheckList: Part 4A Hesperioidea-Papilionoidea'' Scientific Publishers. The number of genera included in Pron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeographic Region
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
