Hamadryas Laodamia
''Hamadryas laodamia'', the starry night cracker or starry cracker, is a species of cracker butterfly in the family Nymphalidae. GBIF It can be found from Mexico to the , but is most common in lowland forest in the Caribbean area. Description The starry night cracker is a black butterfly with iridescent blue speckling on its wings. The female has a white band on the underside of the forewing that is broader than the band on the male. The wingspan is about . The caterpillars have short horns on their heads, the function of which is unknown, and the p ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Cramer
Pieter Cramer (21 May 1721 (baptized) – 28 September 1776), was a wealthy Dutch merchant in linen and Spanish wool, remembered as an entomologist. Cramer was the director of the Zealand Society, a scientific society located in Flushing, and a member of ''Concordia et Libertate'', based in Amsterdam. This literary and patriotic society, where Cramer gave lectures on minerals, commissioned and/or financed the publishing of his book ''De uitlandsche Kapellen'', on foreign (exotic) butterflies, occurring in three parts of the world Asia, Africa and America. Cramer assembled an extensive natural history collection that included seashells, petrifications, fossils and insects of all orders. Many were colourful butterflies and moths ( Lepidoptera), collected in countries where the Dutch had colonial or trading links, such as Surinam, Ceylon, Sierra Leone and the Dutch East Indies. Cramer decided to get a permanent record of his collection and so engaged the painter Gerrit Wartenaar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamadryas (butterfly)
Cracker butterflies are a Neotropical group of medium-sized brush-footed butterfly species of the genus ''Hamadryas''. They acquired their common name due to the unusual way that males produce a "cracking" sound as part of their territorial displays. The most comprehensive work about their ecology and behavior is that of Julian Monge Najera et al. (1998). The genus was erected by Jacob Hübner in 1806. Description Cracker butterflies are all fairly cryptic in their dorsal coloration, commonly covered in varying colored spots, most of which resemble bark; some are known to have little coloration, such as the '' Hamadryas februa''. Distribution and habitat This genus of butterflies are commonly found throughout South America to Arizona, where at least nine species can be found in Costa Rica. (2007).

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.

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon sys ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant community, plant cropping or crop, formed by the collection of individual Crown (botany), plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, Arboreal, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unc ...

Dalechampia Triphylla
''Dalechampia triphylla'' is a vine in the family Euphorbiaceae. It is native to tropical South America. Ecology ''Dalechampia triphylla'' is the food plant of the larvae of several species of "cracker" butterflies. ''Hamadryas feronia'' and '' Hamadryas iphthime'' both feed on the leaves. These butterflies are shades of grey, brown and white, and are well camouflaged when they exhibit their characteristic behaviour and rest on tree trunks. The larvae of '' Hamadryas laodamia'' also feed on the leaves, but this butterfly is black with iridescent blue markings; the adult is avoided by predators Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the ... such as jacamars, and the larvae appear to sequester distasteful toxic compounds present in the plant.

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as '' Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as '' Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unise ...

Aposematism
Aposematism is the Advertising in biology, advertising by an animal to potential predation, 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 animal coloration, coloration, sounds, odours, or other perception, 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 ...

Jacamar
The jacamars are a family, Galbulidae, of near passerine birds from tropical South and Central America, extending up to Mexico. The family contains five genera and 18 species. The family is closely related to the puffbirds, another Neotropical family, and the two families are often separated into their own order, Galbuliformes, separate from the Piciformes. They are principally birds of low-altitude woodlands and forests, and particularly of forest edge and canopy. Taxonomy The placement of the combined puffbird and jacamar lineage was in question, with some bone and muscle features suggesting they may be more closely related to the Coraciiformes. However, analysis of nuclear DNA in a 2003 study placed them as sister group to the rest of the Piciformes, also showing that the groups had developed zygodactyl feet before separating. Per Ericson and colleagues, in analysing genomic DNA, confirmed that puffbirds and jacamars were sister groups and their place in Piciformes. Descript ...

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chamel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
