Question

Where do silk worms originate from?


Thats it really :D

Answer 1

They come from moths that are indeginous to China

Answer 2

Silkworms are the larvae of the Bombyx Morii moth and originated in the Far East. Apocrypha indicates they are from China where their fiber and the method of unreeling the silk from the cocoons was supposedly discovered when a cocoon dropped into a cup of hot tea held by a princess sitting under a mulberry tree. She noticed that the heat and tannic acid in the tea had loosened the end of a strand and she began to pull on it, unreeling the fiber as she did.



Silkworms and cocoons were regulated by law there since nowhere else could such a light and strong fiber be found. Anyone being caught trying to smuggle them out of China was executed to protect the secret of silk. Eventually cocoons were smuggled out, again, apocrypha indicates that they were smuggled out in the hem of the gown a princess wore to her wedding outside the country. Other stories indicate they may have been smuggled out by Marco Polo.



Silk is a continuous strand of what is basically caterpillar spit, much like spinder web silk, and is, for its diameter, stronger than a similar width of steel wire. I can attest to its strength, having had it cut off a fingernail while I was spinning, the fiber simply eroded into the nail and cut it. Shorter lengths of silk may be from cocoons where the moth emerged and broke through the silk.

Answer 3

China. The female silkworm lays more than 300 eggs, which is why it's possible to make so much clothing out of silk. The silkworm makes a silk cocoon which is how we get silk.

Answer 4

silk worms originate

Answer 5

Asia. Specifically, China.

Answer 6

it originated during the 800s AD and the silk worms eat mulberry tree leaves Silk is a "natural" protein fiber, some forms of which can be woven into textiles. The best-known type of silk is obtained from cocoons made by the larvae of the silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance for which silk is prized comes from the fibres' triangular prism-like structure which allows silk cloth to refract incoming light at different angles. Silk is also the strongest natural fiber known to man. Wild silks" are produced by caterpillars other than the mulberry silkworm (Bombyx mori). The term "wild" implies that they are not capable of being domesticated and artificially cultivated like Bombyx mori. A variety of wild silks have been known and used in China, India, Vietnam, and Europe from early times, although the scale of production has always been far smaller than that of cultivated silks. Aside from differences in colours and textures, they all differ in one major aspect from the domesticated varieties: the cocoons that are gathered in the wild have usually already been damaged by the emerging moth before the cocoons are gathered, and thus the single thread that makes up the cocoon has been torn into shorter lengths. Commercially reared silkworm pupae are killed before the adult moths emerge by dipping them in boiling water or piercing them with a needle, thus allowing the whole cocoon to be unravelled as one continuous thread. This allows a much stronger cloth to be woven from the silk. Wild silks also tend to be more difficult to dye than silk from the cultivated silkworm. There is some evidence that small quantities of wild silk were already being produced in the Mediterranean area and the Middle East by the time the superior, and stronger, cultivated silk from China began to be imported (Hill 2003, Appendix C). Many different types of silk are produced by a huge variety of different types of insect (other than moth caterpillars), yet none of these have been exploited for commercial purposes, though there is basic research into the structures of such silks, as there is some variation at the molecular level. It is most commonly produced by larvae, and thus largely limited to insects with complete metamorphosis, but in some cases it is produced by adult insects such as webspinners. Silk production is especially common in the Hymenoptera (bees, wasps, and ants), and is sometimes used in nest construction. Other types of arthropod produce silk, most notably various arachnids such as spiders (see spider silk).

Answer 7

China. They are actually not a worm, but a moth caterpillar.

.

Answer 8

china. That is why it is so expensive, because silk is really hard to make and it is a talent to do so.

Answer 9

asia i think. that is where silk comes from originally
