Papilio Palamedes
''Papilio palamedes'', the Palamedes swallowtail or laurel swallowtail, is a North American butterfly in the family Papilionidae. Description The upperside of the wings is blackish brown with both wings having a yellow postmedian band and a yellow submarginal band.Jim P. Brock and Kenn Kaufman (2003). ''Butterflies of North America''. Houghton Mifflin, New York, NY. There is a yellow bar at the end of the forewing cell. The underside of the wings is black with the forewing having a yellow postmedian band and a yellow submarginal band.

Dru Drury
Dru Drury (4 February 1725 – 15 January 1804) was a British collector of natural history specimens and an entomologist. He received specimens collected from across the world through a network of ship's officers and collectors including Henry Smeathman. His collections were utilized by many entomologists of his time to describe and name new species and he is best known for his book ''Illustrations of natural history'' which includes the names and descriptions of many insects, published in parts from 1770 to 1782 with most of the copperplate engravings done by Moses Harris. Life Dru Drury was born in Wood Street, London. His father, also Dru Drury, was a citizen, goldsmith and silversmith of the City of London. Drury's great-grandfather, William, Lord of the Manor of Colne, Cambridgeshire, Colne, was Sheriff of Cambridgeshire and Huntingdonshire#1600–1699, Sheriff of Cambridgeshire in 1676. The Drury family traced back to a Thomas Drury, of Fincham, Norfolk, who died in 154 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernation
Hibernation is a state of minimal activity and metabolic reduction entered by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering. 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 use 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Dru Drury
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based ("Linnaean taxonomy, Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated f ...

Butterflies Described In 1773
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take ...

Papilio
''Papilio'' is a genus in the swallowtail butterfly family, Papilionidae, as well as the only representative of the tribe Papilionini. The word ''papilio'' is Latin for butterfly. It includes the common yellow swallowtail ('' Papilio machaon''), which is widespread in the Northern Hemisphere and the type species of the genus, as well as a number of other well-known North American species such as the western tiger swallowtail ('' Papilio rutulus''). Familiar species elsewhere in the world include the Mormons (''Papilio polytes'', '' Papilio polymnestor'', '' Papilio memnon'', and '' Papilio deiphobus'') in Asia, the orchard and Ulysses swallowtails in Australia ('' Papilio aegeus'', '' Papilio ulysses'', respectively) and the citrus swallowtail of Africa ('' Papilio demodocus''). Older classifications of the swallowtails tended to use many rather small genera. More recent classifications have been more conservative, and as a result a number of former genera are now absorbed withi ...

Institute Of Food And Agricultural Sciences
An institute is an organizational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute", or institute of technology. In some countries, such as South Korea and India, private schools are sometimes referred to as institutes; also, in Spain, secondary schools are referred to as institutes. Historically, in some countries, institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from the Latin word ''institutum'' ("facility" or "habit"), in turn derived from ''instituere'' ("build", "create", "raise" or "edu ...

Offspring
In biology, offspring are the young creation of living organisms, produced either by sexual reproduction, sexual or asexual reproduction. Collective offspring may be known as a brood or progeny. This can refer to a set of simultaneous offspring, such as the chick (young bird), chicks hatched from one clutch (eggs), clutch of eggs, or to all offspring produced over time, as with the brood (honeybee), honeybee. Offspring can occur after mating, artificial insemination, or as a result of cloning. Human offspring (lineal descendant, descendants) are referred to as children; male children are sons and female children are daughters (see Kinship). Overview Offspring contains many parts and properties that are precise and accurate in what they consist of, and what they define. As the offspring of a new species, also known as a child or f1 generation, consist of genes of the father and the mother, which is also known as the parent generation. Each of these offspring contains numerous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
