Morpho Amathonte
''Morpho amathonte'' is a Neotropical butterfly belonging to the subfamily Morphinae of the family Nymphalidae. It is considered, by some authors, to be a subspecies of ''Morpho menelaus''. The genus ''Morpho'' is palatable but some species (such as ''M. amathonte'') are very strong fliers; birds – even species which are specialized for catching butterflies on the wing – find it very hard to catch them.Young A.M. 1971. Wing colouration and reflectance in ''Morpho'' butterflies as related to reproductive behaviour and escape from avian predators. ''Oecologia'' 7, 209–222. The conspicuous blue coloration shared by most ''Morpho'' species may be a case of Müllerian mimicry, or may be 'pursuit aposematism'.Edmunds M. 1974. ''Defence in Animals: a survey of anti-predator defences''. Harlow, Essex and NY: Longman. . On p255–256 there is a discussion of 'pursuit aposematism': :"Young suggested that the brilliant blue colours and bobbing flight of ''Morpho'' butterflies ...

Émile Deyrolle
Émile Deyrolle (1838–1917) was a French naturalist and natural history dealer in Paris. The business was originally owned by his naturalist grandfather, Jean-Baptiste Deyrolle who opened his shop in 1831 at 23, Rue de la Monnaie. Émile’s father Achille Deyrolle ran the business for many years. Émile took over in 1866. The address from 1881 (and now) was (and is) 46, Rue du Bac, the former home of Jacques Samuel Bernhart. Deyrolle specialized in natural history publications and specimens taxidermy, minerals, rocks, fossils, botanical specimens, shells, taxidermy, microscopic specimens and microscopes.

Neotropical
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphinae
The Morphinae are a subfamily of Nymphalidae butterflies that includes the morphos, the owl butterflies (''Caligo''), and related lineages. It is either considered a sister group of the Satyrinae, or disassembled and included therein. Systematics This group sometimes includes the monotypic (sub)tribe Biina, otherwise placed in the Brassolini. This group is the subject of intense study and the following classification is subject to modification.

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.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morpho Menelaus
The Menelaus blue morpho (''Morpho menelaus'') is one of thirty species of butterfly in the subfamily Morphinae. Its wingspan is approximately , and its dorsal forewings and hindwings are a bright, iridescent blue edged with black, while the ventral surfaces are brown. Its iridescent wings are an area of interest in research because of its unique microstructure. Due to its characteristic blue color, ''Morpho menelaus'' is considered valuable among collectors and was widely hunted in the 20th century. Range This neotropical butterfly is found in Central and South America, including the Cerrado which is a vast tropical savanna in Brazil. Other locations include Mexico and Venezuela. Ancestors of the ''Morpho'' ''menelaus'' butterfly may have been distributed in the Andean regions. Morpho menelaus is one of the six species of Morpho in Costa Rica. The genus of Morpho is present in regions beginning in Mexico and throughout South America, except Chile. Moreover, the Morpho menelau ...

Morpho
The morpho butterflies comprise many species of Neotropical butterfly under the genus ''Morpho''. This genus includes more than 29 accepted species and 147 accepted subspecies, found mostly in South America, Mexico, and Central America. ''Morpho'' wingspans range from for '' M. rhodopteron'' to for ''M. hecuba'', the imposing sunset morpho. The name ''morpho'', meaning "changed" or "modified", is also an epithet. Taxonomy and nomenclature Many names attach to the genus ''Morpho''. The genus has also been divided into subgenera. Hundreds of form, variety, and aberration names are used among ''Morpho'' species and subspecies. One lepidopteristLamas, G. (Ed.) (2004''Checklist: Part 4A. Hesperioidea-Papilionoidea''. Gainesville, Florida: Association for Tropical Lepidoptera. includes all such species within a single genus, and synonymized many names in a limited number of species.

Müllerian Mimicry
Müllerian mimicry is a natural phenomenon in which two or more well-defended species, often foul-tasting and sharing common predators, have come to mimic each other's honest warning signals, to their mutual benefit. The benefit to Müllerian mimics is that predators only need one unpleasant encounter with one member of a set of Müllerian mimics, and thereafter avoid all similar coloration, whether or not it belongs to the same species as the initial encounter. It is named after the German naturalist Fritz Müller, who first proposed the concept in 1878, supporting his theory with the first mathematical model of frequency-dependent selection, one of the first such models anywhere in biology. Müllerian mimicry was first identified in tropical butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals including poison frogs and coral snakes. The mimicry need not be visual; for example, many snakes share a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematism
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences 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 coloration, sounds, odours, or other perceivable characteristics. Aposematic 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. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
