Amiga (butterfly)
''Amiga'' is a monotypic butterfly genus in the family Nymphalidae erected by Shinichi Nakahara, Keith R. Willmott and Marianne Espeland in 2019. ''Amiga arnaca'', formerly of the genus '' Chloreuptychia'', is the only species in the genus ''Amiga''. In 2019, Nakahara et al. described this new genus after molecular phylogenetic research showed it was not closely related to the other species of ''Chloreuptychia''. ''Amiga arnaca'' is found from southern Mexico through most of Central and South America to southern Brazil, and is common in rain and cloud forests. The larvae feed on grasses, including ''Eleusine'', ''Ichnanthus'', '' Lasiacis'', ''Oplismenus'', and ''Paspalum ''Paspalum'' is a genus of plants in the grass family. The group is widespread across much of Asia, Africa, Australia, and the Americas. Commonly known as paspalum, bahiagrasses, crowngrasses or dallis grasses, many of the species are tall pere ...''.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Oplismenus
''Oplismenus'' is a small genus of annual or perennial grasses, commonly known as basketgrass, found throughout the tropics, subtropics, and in some cases, temperate regions of the Americas, Africa, Asia, and Australia. The systematics of the genus are unclear, with over 100 described species, only 7 species are officially recognized as of 2016. Accepted species The following list includes all currently recognized species of the genus ''Oplismenus'' accepted by the Catalogue of Life and World Checklist of Selected Plant Families as of March 2016, sorted alphabetically. For each, binomial name is followed by author citation. Description The members of this genus are scrambling or trailing herbaceous grasses, both annual and perennial.

Paspalum
''Paspalum'' is a genus of plants in the grass family. The group is widespread across much of Asia, Africa, Australia, and the Americas. Commonly known as paspalum, bahiagrasses, crowngrasses or dallis grasses, many of the species are tall perennial New World grasses. They are warm-season C4 grasses and are most diverse in subtropical and tropical regions. ''Paspalum scrobiculatum'' (''koda'', ''varuka'', ''varuku'', etc.) is a millet locally grown as food grain. Some species, such as bahiagrass (''P. notatum'') and '' P. nicorae'', are grown for pasturage, especially with the perennial forage peanut (''Arachis glabrata'') as a companion crop. Bahiagrass has also some significance as a honey plant. Water finger-grass (''P. vaginatum'') resembles bermudagrass (''Cynodon dactylon''), but has a higher salinity tolerance and can consume greywater. It is not infrequently used for arena and golf course turf in warmer coastal regions, such as Baja California, Florida, Peru, Texas ...

Butterflies Described In 1776
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 ...

Euptychiina
The butterfly subtribe Euptychiina ( Lepidoptera: Nymphalidae) is a diverse group within the tribe Satyrini, occurring throughout Central and South America, in addition to a few species known from North America. Euptychiina is a predominantly lowland group, with the exception of one Asian taxon '' Palaeonympha opalina'' Butler, 1871 and the Andean genus '' Forsterinaria'' Gray, 1973. The taxon was erected by Lee Denmar Miller. Euptychiina Despite its members being common, this subtribe has been a challenging subject for taxonomic and phylogenetic studies for many years because of their dull coloration, intraspecific variation, lack of clear morphological characters, and morphological homogeneity. However, with the exception of pioneering work by W. Forster and L. D. Miller, the group received little attention from butterfly researchers until recently due to their typically dull brownish coloration. Currently, 50 genera and over 400 described species are recognized within this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
