Eurytides Marcellus
''Eurytides marcellus'', the zebra swallowtail, (formerly listed under genera ''Protographium'', ''Iphiclides'', '' Graphium'' and ''Papilio'' by some authorities) is a swallowtail butterfly native to the eastern United States and south-eastern Canada. It is the state butterfly of Tennessee. Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees. The green or black caterpillars feed on the leaves of various pawpaw species, while the adults feed on flower nectar and minerals from damp soil. Description The zebra swallowtail has a wingspan of . The triangular wings are white to greenish white with black longitudinal stripes. A pair of swordlike tails extend from the hindwings. The inner margin of the hindwing has two blue spots on the corner and a red spot near the body. A red stripe runs along the middle of ...

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] |
Mud-puddling
Mud-puddling, or simply puddling, is a behaviour most conspicuous in butterflies, but occurs in other animals as well, mainly insects; they seek out nutrients in certain moist substances such as rotting plant matter, mud and carrion and they suck up the fluid. Where the conditions are suitable, conspicuous insects such as butterflies commonly form aggregations on wet soil, dung or carrion.

Annona Muricata
Soursop (also called ''graviola, guyabano'', and in Hispanic America, ''guanábana'') is the fruit of ''Annona muricata'', a broadleaf, flowering, evergreen tree. It is native to the tropical regions of the Americas and the Caribbean and is widely propagated. It is in the same genus, '' Annona'', as cherimoya and is in the Annonaceae family. The soursop is adapted to areas of high humidity and relatively warm winters; temperatures below will cause damage to leaves and small branches, and temperatures below can be fatal. The fruit becomes dry and is no longer good for concentrate. With an aroma similar to pineapple, the flavor of the fruit has been described as a combination of strawberries and apple with sour citrus flavor notes, contrasting with an underlying thick creamy texture reminiscent of banana. Soursop is widely promoted (sometimes as "graviola") as an alternative cancer treatment, but there is no reliable medical evidence it is effective for treating cancer or an ...

Asimina
''Asimina'' is a genus of small trees or shrubs described as a genus in 1763. ''Asimina'' is the only temperate genus in the tropical and subtropical flowering plant family, Annonaceae. ''Asimina'' has large simple leaves and large fruit. It is native to eastern North America and collectively referred to as pawpaw. The genus includes the widespread common pawpaw ''Asimina triloba,'' which bears the largest edible fruit indigenous to the United States. Pawpaws are native to 26 states of the U.S. and to Ontario in Canada. The common pawpaw is a patch-forming (clonal) understory tree found in well-drained, deep, fertile bottomland and hilly upland habitat. Pawpaws are in the same plant family (Annonaceae) as the custard-apple, cherimoya, sweetsop, soursop, and ylang-ylang; the genus is the only member of that family not confined to the tropics. Names The genus name ''Asimina'' was first described and named by Michel Adanson, a French naturalist of Scottish descent. The name ...

Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Osmeterium
The osmeterium is a defensive organ found in all papilionid larvae, in all stages. The organ is situated in the prothoracic segment and can be everted when the larva feels threatened. The everted organ resembles a fleshy forked tongue (not unlike a snake tongue), and this along with the large eye-like spots on the body might be used to startle birds and small reptiles. The osmeterial organ remains inside the body in the thoracic region in an inverted position and is everted when the larva is disturbed in any way emitting a foul, disagreeable odor which serves to repel ants, small spiders and mantids. To humans, this odour is rather strong but pleasant, usually smelling like a concentrated scent of the caterpillar’s food plant and pineapple. The constitution of the osmeterial secretion varies from species to species and contains monoterpene hydrocarbons, sesquiterpenic compounds or a mixture of aliphatic acids and esters The fine structure of the osmeterium of ''Papilio ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
