Answer 1

After every sexual contact, female silkworm insulates 300-400 eggs on the leaves of the mulberry treet In a span of 10 days each and every egg produces a small female insect called larvae also known as Caterpillar. Then in approximately 30 to 40 days, growth takes place, larvae becomes long, sloppy and magnified.

Now continuously for three days this insect spins his head around it and forms the solution of a single long thread which is known as Koya or cocoon or a cocoon is a protective case or shell that the silkworm spins around it. As soon as it comes in contact with the air, this thread solidifies and a silk thread which is about 1000 meters long is formed. Now, these larvae are converted into a pupa.
In the pupa stage the larval structures of the silkworm are broken down forming adult structures and the caterpillar gets transformed into a moth. The cocoon helps the worm to stay protected from the harsh and unfriendly weather conditions. Hence, usually the insects spin a cocoon around them at the start of winter, and spend the entire season inside the cocoon without the need for food and water. This stage is often referred to as the sleeping stage of the silkworm.

Usually in 12 to 15 days, PUPA becomes a silkworm (Imago) by transplantation, which, with the help of an alkaline secretion cut the Koya from one side and comes out. This makes the silk thread of Koya broken into small pieces. Therefore, to obtain silk, the Koya is put into the boiling water, so that the silkworm which is inside it, died there and segregates thread from it. In this way Silk is prepared from Silkworm. And further this silk is used in the manufacture of clothes etc.
