Chironomids
Chironomidae , commonly known as non-biting midges or chironomids , are a family of Nematoceran flies with a global distribution. They are closely related to the families Ceratopogonidae, Simuliidae, and Thaumaleidae. Although many chironomid species superficially resemble mosquitoes, they can be distinguished by the absence of wing scales and elongated mouthparts characteristic of the Culicidae (true mosquitoes). The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects. Some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They ar ...

Chironomus Plumosus
''Chironomus plumosus'', also known as the buzzer midge, is a species of Chironomidae, nonbiting midge (Chironomidae) that occurs throughout areas in the Northern Hemisphere. Description Adult Adults are pale green with brown legs and grow to . Males have feathery antenna (biology), antennae, while females' antennae are sleek. A dark brown band is seen at the end of each abdominal segment. Adults of the sibling species ''C. muratensis'' and ''C. nudiventris'' cannot be distinguished from ''C. plumosus'' based on morphological characters. Immature The larvae are called bloodworms because some larvae are bright red, but they can also be found in brown and almost black. When the larva pupate, they drift towards the surface, making them vulnerable to many types of fish. Other common predators include the Notonecta glauca, common backswimmer (''Notonecta glauca''), Gerris lacustris, common pondskater (''Gerris lacustris''), common toad (''Bufo bufo''), lesser water boatman (''Corixa ...

Ahimsa Silk
Ahimsa silk (: Sanskrit for 'nonviolence'), also known as ''peace silk'' is a method of nonviolent silk breeding and harvesting. Wild silk moths are bred rather than the domestic variety. It allows the completion of the metamorphosis of the silkworm to its moth stage, whereas most silk harvesting requires the silkworms to be killed in their cocoon stage. No animals suffer or die for the silk to be produced, making it a favourable alternative to normal silk for those who object to harming animals. Process The pupa is allowed to hatch and the leftover cocoon is then used to create silk. While the ''Bombyx mori'' (also called mulberry silkworm or mulberry silk moth) are the preferred species for creating ahimsa silk, there are a few other types of species that fall under the category of ahimsa silk, which is defined not necessarily by the species of the moth involved but by the methods for harvesting the cocoon. The other types of silkworm that are used for this process are a subspec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombyx Mori
''Bombyx mori'', commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of '' Bombyx mandarina'', the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the Osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths, which are other species of ''Bombyx'', are not as commercially viable in the production of silk. Sericulture, the practice of breeding silkworms for the production of raw silk, has existed for at least 5,000 years in China, whence it spread to India, Korea, Nepal, Japan, and then the West. The conventional process of sericulture kills the silkworm in the pupal stage. The domestic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironomus
''Chironomus'' is a genus of nonbiting midges in the subfamily Chironominae of the bloodworm family, Chironomidae, containing several cryptic species that can only be distinguished by experts based on the characteristics of their giant chromosomes. In the early 20th century the name ''Tendipes'' Meigen, 1800 was often used instead. In 1963 the International Commission on Zoological Nomenclature restored the traditional name ''Chironomus''. Description Adult ''Chironomus'' are midges with the pronotum widest in the middle and bearing a notch, the head usually bearing a pair of small tubercles above the antennal bases, the antennal flagellum of males having 11 segments, and the male genitalia has inferior volsella large and larger than superior volsella. They range from 5 to 13 mm in length. Larvae are red and usually have tubes on the side or bottom of the eighth abdominal segment. These features are not unique to ''Chironomus'', also being found in some related genera. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silk
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Harvested silk is produced by several insects; but, generally, only the silk of various moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gr ...

Belgica Antarctica
''Belgica antarctica'', the Antarctic midge, is a species of flightless midge, endemic to the continent of Antarctica. At long, it is the largest purely terrestrial animal native to the continent. It also has the smallest known insect genome as of 2014, with only 99 million base pairs (Mbp) of nucleotides and about 13,500 genes. It is the only insect that can survive year-round in Antarctica. Taxonomy and etymology The first specimens of ''Belgica antarctica'' were collected on the Belgian Antarctic Expedition (1897–1899). During this expedition organized by the Belgian Government, Romanian biologist Emil Racoviță collected, among other specimens, a flightless midge and its larvae. Based on these specimens, the Belgian doctor and entomologist, Jean-Charles Jacobs, described ''Belgica antarctica'' Jacobs, 1900. Jacobs named the new genus and species of insect after the location where it was collected off the Antarctic Peninsula, "''canal de la Belgica antarctica''" (Belgian ...

Sandfly
Sandfly or sand fly is a colloquial name for any species or genus of flying, biting, blood-sucking dipteran (fly) encountered in sandy areas. In the United States, ''sandfly'' may refer to certain horse flies that are also known as "greenheads" (family '' Tabanidae''), or to members of the family ''Ceratopogonidae''. The bites usually result in a small, intensely itchy bump or welt, the strength of which intensifies over a period of 5-7 days before dissipating. Sandfly bites can be distinguished from mosquito bites as sandfly bite are usually found in clusters as they attack animals in groups. Moderate relief is achieved with varying success through the application of over-the-counter products such as Benadryl (ingested) or an analgesic cream such as After Bite (applied topically). Outside the United States, ''sandfly'' may refer to members of the subfamily Phlebotominae within the Psychodidae. Biting midges (Ceratopogonidae) are sometimes called sandflies or no-see-ums ...
