Being in a worm like state ex. maggots, caterpillars, silk worms...
well, catapillars dont really spin silk, silk worms make silk. catapillars make a sort of spider string but only when they cacoon themselfs up.
Many species of catepillars and worms are dosmestic and raised for human benefit. Perhaps the most well-known example is of the silk worm (Bombyx mori)
Silk is the material produced by the silk worm to make its cocoon. The silkworm that makes the best quantity of silk is the mulberry silkworm. Shortly before the silkworm is going to eat its way through the silk of the cocoon, the worm is killed by humans so the cocoon can be unraveled into a single thread.
silk worms are tiny worms hanging from silk on a tree
yes,there is a market for silk from silk worms.
Silk worms create silk. That's where silk comes from.
Silk is not made out of silk worms. Silk is made by silk worms which spin to make a cocoon for themselves.
As a group, the silk worms have a corner on this answer: it's they who produce the most silk used by humans as fibre. If, however, you want to know which animals -- spiders, caterpillars and so forth, produce the most 'silk', your answer may depend on a more narrowly defined question.
No. Many kinds of insects and spiders produce silk.
Caterpillars form their cocoons out of silk. They have silk glands near their mouths that weave the silk, which they then wrap around their body to form the cocoon.
first you raise silk "worms" they are really caterpillars and turn into moths. Then you kill them all by boiling the cocoons which they weave. The substance the cocoons are made of is raw silk which is later cleaned and woven into threads in a similar way cotton is.
