The silk worm spins its cocoon in order to create a protective container in which it can carry out its metamorphosis without being disturbed.

Do silk moths produce silk?
Yes. Silk fibre comes from their cocoons.
Is silk man made or natural?
natural. silk is made by silk wormsSilk is a natural fibre produced by silk worms -- moths, really -- that spin cocoons which, when unraveled upon the death of the worm, become silk strands.
How you get silk from butterfly?
Silkworms, which emerge from their cocoons as moths, spin cocoons that are the raw material for the fibre humans use as silk. Cocoons are harvested from domesticated silkworms by heating the cocoon to kill the animal, then the silk cocoon is unraveled. Once the moth has emerged -- in wild silkworms for example, the cocoon's silk can be harvested, but not in one continuous length. As a moth, there is no connection with the now-discarded cocoon.
Why are some cocoons boiled during harvesting of silk thread?
It must be kept in mind that about 1 per cent of total harvest of cocoons is not boiled. The insects within the cocoon are allowed to mature to form silk moths. These silk moths cut through the cocoons and are allowed to breed for silk worm eggs for future production of silk. The silk from the damaged cocoons is collected and mixed with the filaments of coarse outer portion of the cocoon as well as from the inner portions of cocoons which is left after reeling. This mixture is then spun to obtain low grade silk yarn..by DEEPANKAR MECH

Do butterflies make coccon?
Bu6terflies make chrysalises rather than cocoons. Moths make cocoons out of silk and butterflies make chrysalises during their molting.
What is the process for making silk fabric?
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.
Do butterflies spin cocoons?
No, butterflies form chrysalids but some species spin silk onto leaves to form a hibernaculum out of the leaf.
How do silkworms spin cocoons?
they secreet it to build the coccon which we collect and weave into silk
Where is silk from originally?
it is originally from these type of worms called silkworms and the silk comes from the webs made by the worms.
What are some similar things between butterflies and moths?
A silkworm is actually a caterpillar, not a worm. There cocoons are made from silk. That is how they make the silk, they actually boil the cocoons with the 'worm' still inside and then through unthreading the cocoons they start the process of making silk that you can use. Unfortunately the caterpillars die as they are 'cooked' alive.
What is the difference between a moth and a silk moth?
"Silk moth" can either refer to Bombyx mori, the species used in the commercial production of silk, or any moth in the family Saturniidae (giant silk moths). Both of these are types of moths. Bombyx mori is a medium-sized white moth with large feathery antennae that was native to China and east Asia. Saturniidae, commonly called "giant silk moths" are a very diverse group of moths found throughout the world. They tend to be large moths with gaudy colors whose caterpillars spin thick silken cocoons. The silk of Saturniidae has not been successfully used for commercial purposes.
