How many kg of mulberry leaves does a silkworm eat?
One laying contains 450 – 500 eggs and needs 12 – 15 kg mulberry leaves for its rearing. On an Average 70 – 80 kg of cocoon yield can be obtained/ 100 DFLs. Production of 1 kg of cocoon needs 18 – 20 kg of mulberry leaves but it is dependent on variety, quality of mulberry leaves and season of rearing.
How much does a silkworm eat daily?
Small Silkworms do not eat as much as older worms. Leaves should be added at least once per day. Ideally, give leaves two-three times per day when the Silkworms reach full size.

Do silkworms sleep?
Silkworms experience four phases in their life cycles: egg, larva (worm), chrysalis, and the moth. Silk worms sleep for four times in this phase, and molt during each hibernation. Each hibernation phase (molting) takes around 24 to 48 hours depending on the instars.
Can you make silk without killing the worm?
Ahimsa Silk, also known as peace silk, cruelty-free silk and non-violent silk, refers to any type of silk that is produced without harming or killing the silk worms. This is in contrast to conventional silk, whereby cocoons are steamed, boiled, or dried in the sun, killing the silk larvae inside.
How many silkworms are needed to produce 1kg of silk?

What is the best food for silkworms?
Silkworms are oligophagous insects, and mulberry leaves are their best food source. All nutrients and water silkworms need come from mulberry leaves, which is a result of the long-term co-evolution and natural selection between silkworms and mulberry trees7, 8.
