Parasemia
''Arctia plantaginis'', the wood tiger, is a moth of the family Erebidae. Several subspecies are found in the Holarctic ecozone south to Anatolia, Transcaucasus, northern Iran, Kazakhstan, Mongolia, China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ..., Korea and Japan. One subspecies is endemic to North America. This species was formerly a member of the genus ''Parasemia'', but was moved to ''Arctia'' along with the other species of the genera ''Acerbia'', ''Pararctia'', ''Parasemia'', ''Platarctia'', and ''Platyprepia''. ''P. plantaginis'' males occur predominantly in two distinct color phenotypes: yellow and white. They are aposematic, meaning their colorations serve to deter predators from attacking. In populations of aposematic species, it is common to have a single color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arctiina
The Arctiina are a subtribe of moths in the family Erebidae. Taxonomy The subtribe was previously treated as a higher-level taxon, the tribe Arctiini, within the lichen and tiger moth family Arctiidae. The ranks of the family and its subdivisions were lowered in a recent reclassification while keeping the contents of the family and its subdivisions largely unchanged. These changes in rank triggered changes in the suffixes in the names. The family Arctiidae as a whole was reclassified as the subfamily Arctiinae within the family Erebidae. The original subfamilies were lowered to tribes, and the original tribe Arctiini was lowered to subtribe status as Arctiina. Thus the name "Arctiini" used to refer to the subtribe that is the topic of this article, but now that name refers to the tribe that includes this subtribe. Genera As a result of research published in 2016 by Rönkä et al., 33 genera of Arctiina were determined to be new taxonomic synonyms of 5 genera, leaving the followi ...

Lepidoptera In The 10th Edition Of Systema Naturae
In the 10th edition of ''Systema Naturae'', Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Butterflies and moths were brought together under the name Lepidoptera. Linnaeus divided the group into three genera – ''Papilio'', ''Sphinx'' and ''Phalaena''. The first two, together with the seven subdivisions of the third, are now used as the basis for nine superfamily names: Papilionoidea, Sphingoidea, Bombycoidea, Noctuoidea, Geometroidea, Tortricoidea, Pyraloidea, Tineoidea and Alucitoidea. Themes When naming the nearly 200 species of butterflies known to him at the time, Linnaeus used names from classical mythology as specific names. These were thematically arranged into six groups, and were drawn from classical sources including the ''Fabulae'' of Gaius Julius Hyginus and Pliny the Elder's ''Naturalis Historia''. The first such group was the ''Equites'', or knights, which were divided into the ''Equites Trojani'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanin
Melanin (; from el, μέλας, melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Eumelanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid tyrosine is followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. Functionally, eumelanin serves as protection against Ultraviolet, UV radiation. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin. Pheomelanin, which is produced when melanocytes are malfunctioning due to derivation of the gene to its recessive format is a cysteine-derivative that contains polybenzothiazine portions that are largely responsible for the of red yellow tint given to some skin or hair colors. Neuromelanin is found in the brain. Research ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arctia
''Arctia'' is a genus of tiger moths in the family Erebidae. Therein, it belongs to the subtribe Arctiina in the tribe Arctiini in the subfamily Arctiinae. Species are well distributed throughout North America, Palearctic, India, and Sri Lanka. As a result of phylogenetic studies by Rönkä et al. in 2016, the following genera were determined to be synonyms with ''Arctia'', and their species were reclassified in this genus. :''Acerbia'' :''Ammobiota'' :''Atlantarctia'' :''Borearctia'' :''Callarctia'' :''Chionophila'' :''Eupsychoma'' :''Gonerda'' :''Nemeophila'' :''Oroncus'' :''Pararctia'' :''Platarctia'' :''Platyprepia'' :''Preparctia'' :''Sinoarctia'' Description Palpi porrect (extending forward), reaching beyond the frons where the first two joints are hairy. Antennae bipectinated in male, with short branches swollen at extremity, and with a terminal bristle, whereas female has serrate. Legs hairy with hind tibia bears two spur pairs. Forewings rather short and broad. Spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Tit
The Eurasian blue tit (''Cyanistes caeruleus'') is a small passerine bird in the tit family, Paridae. It is easily recognisable by its blue and yellow plumage and small size. Eurasian blue tits, usually resident and non-migratory birds, are widespread and a common resident breeder throughout temperate and subarctic Europe and the western Palearctic in deciduous or mixed woodlands with a high proportion of oak. They usually nest in tree holes, although they easily adapt to nest boxes where necessary. Their main rival for nests and in the search for food is the larger and more common great tit. The Eurasian blue tit prefers insects and spiders for its diet. Outside the breeding season, they also eat seeds and other vegetable-based foods. The birds are famed for their acrobatic skills, as they can hold on to the outermost branches of trees and shrubs and hang upside down when looking for food. Taxonomy The Eurasian blue tit was described by Carl Linnaeus in 1758 in the 10th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moths Described In 1758
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Phenotypic Plasticity
Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be permanent throughout an individual's lifespan. The term was originally used to describe developmental effects on morphological characters, but is now more broadly used to describe all phenotypic responses to environmental change, such as acclimation (acclimatization), as well as learning. The special case when differences in environment induce discrete phenotypes is termed polyphenism. Generally, phenotypic plasticity is more important for immobile organisms (e.g. plants) than mobile organisms (e.g. most animals), as mobile organisms can often move away from unfavourable environments. Nevertheless, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-oxidant
Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals. This can lead to polymerization and other chain reactions. They are frequently added to industrial products, such as fuels and lubricants, to prevent oxidation, and to foods to prevent spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress. The only dietary antioxidants are vitamins A, C, and E, but the term ''antioxidant'' has also been applied to numerous other dietary compounds that only have antioxidant properties in vitro, with little evidence for antioxidant properties in vivo. Dietary supplements marketed as antioxidants have not been shown to maintain health or prevent disease in humans. History As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxidants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
