Question

Name the fibre of which cocoon is made​

Answer 1

Answer:

Explanation:

Cocoon is defined as the protective covering that is made from silky threads that cover the larvae of moths and other insects such as butterflies. Cocoon is the place where the larvae grow into adult insects. The pupa is the stage which is covered in the cocoon.

Answer 2

When a pupa is through metamorphosis to become an adult, it creates a cocoon.

Explanation:

The cocoon is formed of a single delicate silk thread.

• A single strand of thin silk thread forms the cocoon. The cocoon must be retrieved and the threads must be taken out in order to obtain the silk.
• This is accomplished by immersing the cocoons in boiling water or dry baking them, causing the pupa to die rather than emerge from the cocoon. Boiling the cocoon also makes the silk less fragile.
• This aids in the removal of the silk fibres' threads. Silk reeling is the term for this process.
