Spilarctia Obliqua
''Spilosoma obliqua'', the jute hairy caterpillar or Bihar hairy caterpillar, is a moth of the family Erebidae. It is found in south-eastern Afghanistan, northern Pakistan, India, Bhutan, Bangladesh and Myanmar. Subspecies *''Spilarctia obliqua obliqua'' (Walker, 1855) (south-eastern Afghanistan, northern Pakistan, India, Bhutan, Bangladesh, Burma) *''Spilarctia obliqua montana'' (Guérin-Méneville, 1843) (southern India) Description The caterpillar has a black head, tufts of black hairs behind this, and similar tufts of yellow hairs on the remaining portion.

Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it “It is to him raythat the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, the publication of which beg ...

Jute
Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. "Jute" is the name of the plant or fiber used to make burlap, hessian, or gunny cloth. Jute is one of the most affordable natural fibers and second only to cotton in the amount produced and variety of uses. Jute fibers are composed primarily of plant materials cellulose and lignin. Jute fiber falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax ( linen), ramie, etc. The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and 1–4 meters (3–13 feet) long. Jute is also called the "golden fiber" for its color an ...

Moths Described In 1855
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. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establis ...

Predation
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 host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Chrysalis
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as #Chrysalis, ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as #Cocoon, cocoons, nests, or Animal shell, shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Braconid
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', ''Apanteles'', ''Asobara'', '' Bracon'', ''Cenocoelius'', '' Chaenusa'', ''Chorebus'', ''Cotesia'', '' Dacnusa'', '' Diachasma'', ''Microgaster'', ''Opius'', ''Parapanteles'', '' Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandibles. These ...

Corchorus Capsularis
''Corchorus capsularis'' (also known as patsun), commonly known as white jute, is a shrub species in the family Malvaceae. It is one of the sources of jute fibre, considered to be of finer quality than fibre from ''Corchorus olitorius'', the main source of jute. The leaves are used as a foodstuff and the leaves, unripe fruit and the roots are used in traditional medicine. Description ''Corchorus capsularis'' is an erect, annual shrub, with acute leaves, yellow five-petaled flowers and growing to two or more metres in height. It has globular fruits. It probably originated in China but is now grown in Bangladesh and India, and found spread across much of tropical Africa. It is also cultivated in the Amazon region of Brazil. Uses Fibre made from ''C. capsularis'' is whiter and of a higher quality than that made from '' ''C. olitorius''''. The fibre is extracted from the cut stems by retting in water, removing the soft tissue, curing the fibre and drying it. It is used for making sac ...

Corchorus Olitorius
Jute mallow or nalta jute (''Corchorus olitorius'', also known as " Jew's mallow", "tossa jute", "bush okra", "krinkrin", "etinyung", "Mulukhiyah", Ademe (Adémé, in Togo) and "West African sorrel", among many other local names, often invoking the most important traits) is a species of shrub in the family Malvaceae. Together with '' C. capsularis'' it is the primary source of jute fiber. The leaves and young fruits are used as a vegetable, the dried leaves are used for tea and as a soup thickener, and the seeds are edible. Origin and history It is unclear whether ''Corchorus olitorius'' originated in Africa or in Asia. Some authorities consider that it comes from the Indo-Burmese area or from India, along with several other related species. Others point out that there is a greater genetic variation in Africa and a larger number of wild species in the genus ''Corchorus''. Wherever it originated, it has been under cultivation for a very long time in both continents and probably gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
