first stages eggs which is kept in the temperature of 25 degree Celsius to 31 degree Celsius for 21 days then the 2nd stage is Larvae which is also known as caterpillars that feeds on Mulberry leaves for 2 to 3 weeks then the 3rd stage in coccon on which which is liquid protein raped on Lava that's the definition of account then the Cockroach develops into silkworm it is 200 to 300 eggs then it dies then again the eggs developed into Larvae and the Cockroach and cocoon to Silk thanks hope this will help you. that is the life cycle of a silkworm then the Silk is made first step of making Silk is releasing Silk worms which I told you then the second step is excreting thread from them they are put in the parts of boiling water to kill the insect inside and to make the outer coating soft and lose than the thread is pulled out from the cocoon by a special technique is single thread is pulled and reeled this process is called reeling of silk then the fibres are going to dying and spinning it is died in two different colours and different qualities are spreading by this process then the process is weaving yarn is woven into beautiful fibres

1. The silk moth lays thousands of eggs.
2. The silk moth eggs hatch to form larvae or caterpillars, known as silkworms.
3. The larvae feed on mulberry leaves.
4. Having grown and moulted several times silkworm weaves a net to hold itself
5. It swings its head from side to side in a figure '8' distributing the saliva that will form silk.
6. The silk solidifies when it contacts the air.
7. The silkworm spins approximately one mile of filament and completely encloses itself in a cocoon in about two or three days. The amount of usable quality silk in each cocoon is small. As a result, about 2500 silkworms are required to produce a pound of raw silk
8. The intact cocoons are boiled, killing the silkworm pupae.
9. The silk is obtained by brushing the undamaged cocoon to find the outside end of the filament.
10. The silk filaments are then wound on a reel. One cocoon contains approximately 1,000 yards of silk filament. The silk at this stage is known as raw silk. One thread comprises up to 48 individual silk filaments.
