Heliconiinae
The Heliconiinae, commonly called heliconians or longwings, are a subfamily of the brush-footed butterflies (family (biology), family Nymphalidae). They can be divided into 45–50 genera and were sometimes treated as a separate family Heliconiidae within the Papilionoidea. The colouration is predominantly reddish and black, and though of varying wing shape, the forewings are always elongated tipwards, hence the common name. Most longwings are found in the Tropics, particularly in South America; only the Argynnini are quite diverse in the Holarctic. Especially tropical species feed on poisonous plants, characteristically Passifloraceae vines, as larvae, becoming poisonous themselves. The adult butterflies announce their acquired toxicity with strong aposematic colours, warning off would-be predators. There are several famous cases of Batesian mimicry, Batesian and Müllerian mimicry both within this group and with other butterflies. Other commonly seen food plants are Fabaceae ( ...

Argynnini
Argynnini is a Tribe (biology), tribe of butterfly, butterflies in the subfamily Heliconiinae, containing some of the fritillaries. This group has roughly 100 species worldwide and roughly 30 in North America. Systematics This group has also been classified as subtribe Argynnina of the Heliconiini, or even as a distinct subfamily Argynninae in the Nymphalidae. Genera Following studies of molecular phylogeny, genus delimitation has been unstable in recent years. Several earlier genera are now junior synonyms of ''Argynnis'' (''Argyreus'', ''Argyronome'', ''Damora'' and others, but ''Speyeria'' and ''Fabriciana'' have been split off again). Similarly, ''Boloria'' now includes ''Clossiana'' and ''Proclossiana'', and ''Issoria'' includes ''Kuekenthaliella''. * ''Euptoieta'' Doubleday, 1848 * ''Pardopsis'' Trimen, 1887 (uncertain placement, possibly in Acraeini, although more recent analysis places the genus in Argynnini) * ''Yramea'' Reuss, 1920 * ''Boloria'' Moore, 1900 (now inclu ...

Acraeini
The Acraeini are a tribe (biology), tribe of butterflies of the subfamily Heliconiinae in the family Nymphalidae. Genera The recognized genera are: Tree of Life * ''Abananote'' Potts, 1943 * ''Acraea (genus), Acraea'' Fabricius, 1807 – acraeas * ''Actinote'' Hübner, [1819] – actinotes * ''Altinote'' Potts, 1943 – altinotes * ''Bematistes'' Hemming, 1935 *''Cethosia'' (Fabricius, 1807) – lacewings * ''Miyana (butterfly), Miyana'' (Fruhstorfer, 1914) The genus ''Acraea'' is highly paraphyletic and needs to be redelimited. This will possibly re-establish the old genus ''Telchinia'', and perhaps others. The genus ''Pardopsis'' Trimen, 1887, previously included in Acraeini, has tentatively been moved to the Argynnini tribe.

Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. In the simplest case, as in Batesian mimicry, a mimic resembles a model, so as to deceive a dupe, all three being of different species. A Batesian mimic, such as a hoverfly, is harmless, while its model, such as a wasp, is harmful, and is avoided by the dupe, such as an insect-eating bird. Birds hunt by sight, so the mimicry in that case is visual, but in other cases mimicry may make use of any of the senses. Most types of mimicry, including Batesian, are deceptive, as the mimics are not harmful, but Müllerian mimicry, where different harmful species resemble each other, is Honest signal, honest, as when species of wasps and of bees all have genuinely Aposematism, aposematic warning coloration. More complex types may be bipolar, involving only two speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliconius
''Heliconius'' comprises a colorful and widespread genus of brush-footed butterflies commonly known as the longwings or heliconians. This genus is distributed throughout the tropical and subtropical regions of the New World, from South America as far north as the southern United States. The larvae of these butterflies eat passion flower vines (Passifloraceae). Adults exhibit bright wing color patterns which signal their distastefulness to potential predators. Brought to the forefront of scientific attention by Victorian naturalists, these butterflies exhibit a striking diversity and mimicry, both amongst themselves and with species in other groups of butterflies and moths. The study of ''Heliconius'' and other groups of mimetic butterflies allowed the English naturalist Henry Walter Bates, following his return from Brazil in 1859, to lend support to Charles Darwin, who had found similar diversity amongst the Galápagos finches.

Brush-footed Butterflies
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.

Batesian Mimicry
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, who worked on butterflies in the rainforests of Brazil. Batesian mimicry is the most commonly known and widely studied of mimicry complexes, such that the word mimicry is often treated as synonymous with Batesian mimicry. There are many other forms however, some very similar in principle, others far separated. It is often contrasted with Müllerian mimicry, a form of mutually beneficial convergence between two or more harmful species. However, because the mimic may have a degree of protection itself, the distinction is not absolute. It can also be contrasted with functionally different forms of mimicry. Perhaps the sharpest contrast here is with aggressive mimicry where a predator or parasite mimics a harmless species, avoiding detection and improving its ...

Passifloraceae
The Passifloraceae are a family of flowering plants, containing about 750 species classified in around 27 genera. They include trees, shrubs, lianas, and climbing plants, and are mostly found in tropical regions. The family takes its name from the passion flower genus (''Passiflora'') which includes the edible passion fruit (''Passiflora edulis''), as well as garden plants such as maypop and running pop. ''Passiflora'' vines and '' Dryas iulia'' (among other heliconian butterflies) have demonstrated evidence of coevolution, in which the plants attempted to stop their destruction from larval feeding by the butterflies, while the butterflies tried to gain better survival for their eggs. The former Cronquist system of classification placed this family in the order Violales, but under more modern classifications systems such as that proposed by the Angiosperm Phylogeny Group, this is absorbed into the Malpighiales and the family has been expanded to include the former Malesherb ...

Cladistic
Cladistics ( ; from Ancient Greek 'branch') is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a ' grade', which are fruitless to precisely delineate, especially when ...

Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematic
Aposematism is the Advertising in biology, advertising by an animal, whether terrestrial or marine, to potential predation, predators that it is not worth attacking or eating. This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous animal coloration, coloration, sounds, odours, or other perception, perceivable characteristics. Aposematic Signalling theory, signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. ...
