Heliconius Eratosignis
''Heliconius eratosignis'', the eratosignis longwing, is a butterfly of the family Nymphalidae. It was described by James John Joicey and George Talbot in 1925. It is found in the south-western Amazon basin, from Brazil to Peru and Bolivia. The habitat consists of sandy rainforests. The larvae are gregarious and feed on species in the ''Passiflora'' subgenera ''Astrophea'' and ''Mitostemma''. Full-grown larvae have a yellow body with black bands and a black head. They reach a length of about 20 mm. Adult ''H. eratosignis'' are distinguished morphologically from their sister species '' Heliconius demeter'' because they lack a yellow streak on the base of the forewing costa underside; in contrast, ''H. eratosignis'' has a solid orange basal costal margin on the underside of the forewing. Keith S. Brown and Woodruff W. Benson in 1975 argued the two forms were the same species, but recorded both ''H. eratosignis'' gregarious and ''H. demeter'' solitary larvae in their paper. ...

James John Joicey
James John Joicey FES (28 December 1870 – 10 March 1932) was an English amateur entomologist, who assembled an extensive collection of Lepidoptera in his private research museum, called the Hill Museum, in Witley, Surrey. His collection, 40 years in the making, was considered to have been the second largest in the world held privately and to have numbered over 1.5 million specimens. Joicey was a fellow of the Zoological Society of London, the Royal Geographical Society, the Royal Entomological Society, the Royal Horticultural Society, and the Linnean Society of London. Joicey employed specialist entomologists including George Talbot to curate his collection and financed numerous expeditions throughout the world to obtain previously unknown varieties. More than 190 scientific articles were produced during the active period of the Hill Museum. This body of research was described as "a contribution to the study of the exotic Lepidoptera of very great scient ...

Heliconius Demeter
''Heliconius demeter'', the Demeter longwing, is a butterfly of the family Nymphalidae. It was described by Otto Staudinger in 1897. It is found in the Northern and Eastern part of the Amazon basin, from Guyana to Northern Brazil and Peru. The habitat consists of sandy rainforests. The larvae are solitary and feed on ''Dilkea'' (Passifloraceae) species. Full-grown larvae have a yellow body with black spots and a black head. They reach a length of about 20 mm. Adult ''H. demeter'' are distinguished morphologically from their sister species ''Heliconius eratosignis'' because they have a yellow streak on the base of the forewing costa underside; in contrast, ''Heliconius eratosignis'' has a solid orange basal costal margin on the underside of the forewing. Brown & Benson in 1975 recognized these differences but argued that the two forms were subspecies of the same species. They also recorded both ''Heliconius eratosignis'' gregarious and ''H. demeter'' solitary larvae in their ...

Fauna Of The Amazon
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ...

Lepidoptera Of French Guiana
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ...

Nymphalidae Of South America
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. Nomenclature Rafinesque introduced ...

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. Model for evolutionary study ''Heliconius'' b ...

Heliconius Erato
''Heliconius erato'', or the red postman, is one of about 40 neotropical species of butterfly belonging to the genus ''Heliconius''. It is also commonly known as the small postman, the red passion flower butterfly, or the crimson-patched longwing. It was described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. ''H. erato'' exhibits Müllerian mimicry with other ''Heliconius'' butterflies such as ''Heliconius melpomene'' in order to warn common predators against attacking, which contributes to its surprising longevity. It also has a unique mating ritual involving the transfer of anti-aphrodisiacs from males to females. Recent field work has confirmed the relative abundance of this butterfly. Habitat and home range ''H. erato'' is a neotropical species, found from southern Texas to northern Argentina and Paraguay, and resides on the edges of tropical rainforests. It is philopatric, having a particularly restricted home range. In areas of dense population in ...

Tree Of Life Web Project
The Tree of Life Web Project is an Internet project providing information about the diversity and phylogeny of life on Earth. This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The site has not been updated since 2011, however the pages are still accessible. The pages are linked hierarchically, in the form of the branching evolutionary tree of life, organized cladistically. Each page contains information about one particular group of organisms and is organized according to a branched tree-like form, thus showing hypothetical relationships between different groups of organisms. In 2009 the project ran into funding problems from the University of Arizona. Pages and Treehouses submitted took a considerably longer time to be approved as they were being reviewed by a small group of volunteers, and apparently, around 2011, all activities ended. History The idea of this project started in the late 1980s. David Maddison was wor ...

Passiflora
''Passiflora'', known also as the passion flowers or passion vines, is a genus of about 550 species of flowering plants, the type genus of the family Passifloraceae. They are mostly tendril-bearing vines, with some being shrubs or trees. They can be woody or herbaceous. Passion flowers produce regular and usually showy flowers with a distinctive corona. There can be as many as eight coronal series, as in the case of ''P. xiikzodz''. The flower is pentamerous and ripens into an indehiscent fruit with numerous seeds. List of species Distribution ''Passiflora'' has a largely neotropic distribution, unlike other genera in the family Passifloraceae, which includes more Old World species (such as the genus ''Adenia''). The vast majority of ''Passiflora'' are found in Mexico, Central America, the United States and South America, although there are additional representatives in Southeast Asia and Oceania. New species continue to be identified: for example, '' P. xishuangbannaensis ...

George Talbot (entomologist)
George Talbot FES (26 October 1882 – 13 April 1952) was an English entomologist who specialised in butterflies. He wrote about 150 scientific papers, the majority being primarily systematic, consisting of the description of new species or the revision of various genera. He was also responsible for the curation and preservation of the Joicey collection of Lepidoptera prior to its accession by the Natural History Museum. Life and career George Talbot was born "in rather humble circumstances" in Croydon, Surrey, in 1882. As a young man, he was assistant to Percy Ireland Lathy. He then curated for the wealthy amateur butterfly collector Herbert Adams, followed by the insect dealer William Frederick Henry Rosenberg. During the First World War he worked with Arthur Bacot at the Lister Institute on trench fever and typhus diseases carried by lice. From 1915, he was head curator of the large and increasing collection of amateur lepidopterist James John Joicey at the Hill Museu ...

Gregarious
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal''. The highe ...
