Cynthia Moth
''Samia cynthia'', the ailanthus silkmoth, is a saturniid moth, used to produce silk fabric but not as domesticated as the silkworm, ''Bombyx mori''. The moth has very large wings of , with a quarter-moon shaped spot on both the upper and lower wings, whitish and yellow stripes and brown background. There are eyespots on the outer forewings. The species was first described by Dru Drury in 1773. Eri silk The common name, ailanthus silkmoth, refers to the host plant ''Ailanthus''. There is a subspecies, ''S. cynthia ricini'' in India and Thailand that feeds upon the leaves of castor bean (''Ricinus communis''), and is known for the production of eri silk, and is often referred to by the common name eri silkmoth. The eri silk worm is the only completely domesticated silkworm other than ''Bombyx mori''. The silk is extremely durable, but cannot be easily reeled off the cocoon and is thus spun like cotton or wool. Range Peigler & Naumann (2003),Peigler, R.S. & Naumann, S., 200 ...

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] |
Instar
An instar (, from the Latin '' īnstar'' 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs 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 ny ...

Moths Described In 1773
Moths are a group of insects that includes all members of the order Lepidoptera that are not butterflies. They were previously classified as suborder Heterocera, but the group is paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although 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.

Saturniinae
The Saturniinae or saturniines are a subfamily of the family Saturniidae, also known as giant silkmoths. They are commonly known as emperor moths or wild silk moths. They are easily spotted by the eyespots on the upper surface of their wings. Some exhibit realistic eye-like markings, whilst others have adapted the eyespots to form crescent moon or angular shapes or have lost their wing scales to create transparent windows. They are medium to very large moths, with adult wingspans ranging from 7.5 to 15 cm, in some cases even more. They consist of some of the largest sized Lepidoptera, such as the luna moth, atlas moth, and many more. The Saturniinae is an important source of wild silk and human food in many different cultures. The saturniine genera, approximately 169 in number, are divided into four major and one minor ( Micragonini) tribes. The genus '' Adafroptilum'' presently consists of a group of species with undetermined relationships. Adults in the Saturniinae typ ...

Sericulture
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the Bombyx mori, domestic silkmoth is the most widely used and intensively studied silkworm. This species of silkmoth is no longer found in the wild as they have been modified through selective breeding, rendering most flightless and without defense against predators. Silk is believed to have first been produced in China as early as the Neolithic period. Sericulture has become an important Putting-out system#Cottage industry, cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, Russia, and Thailand. Today, China and India are the two main producers, with more than 60% of the world's annual production. History According to Confucius, Confucian text, the discovery of silk production dates to about 2700 BCE, although archaeological records point to silk cultivation as early as the Yangshao ...

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced species, introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native, though many localities define them as necessarily being non-native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forestry, forest management, nature reserves, regional park, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introd ...

Ailanthus Altissima
''Ailanthus altissima'' ( ), commonly known as tree of heaven or ailanthus tree, is a deciduous tree in the quassia family. It is native to northeast and central China, and Taiwan. Unlike other members of the genus ''Ailanthus'', it is found in temperate climates rather than the tropics. The tree grows rapidly, and is capable of reaching heights of in 25 years. While the species rarely lives more than 50 years, some specimens exceed 100 years of age. It is considered a noxious weed and vigorous invasive species, and one of the worst invasive plant species in Europe and North America. In 21st-century North America, the invasiveness of the species has been compounded by its role in the life cycle of the also destructive and invasive spotted lanternfly. Description ''Ailanthus altissima'' is a medium-sized tree that reaches heights between with a diameter at breast height of about . The bark (botany), bark is smooth and light grey, often becoming somewhat rougher w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
