Silk is a natural fiber derived from worm larvae, which are the larvae of the mulberry silk moth Bombyx mori.

The Life Cycle of the Silkworm
– The female moth lays 300-500 small eggs and after 10 days, the silkworms hatch.
– Worms only eat a lot of leaves on a mulberry tree for about 30-40 days.
– Silk larvae shed their skin up to four times, or molt, as they continue to feed and grow.
– After their last larva, the embryo forms a cocoon itself. The cocoon is a protective coating made from silk.
– Inside the coconut, the silkworm turns into a caterpillar, the stage between the caterpillars and the old moths.
– After two weeks, the caterpillar comes out of the hole like an old moth.
– The old moth is looking for a mate so that the female can lay more eggs and start the cycle again.
– A cord from a marble coconut when not open can be up to 900 meters long
– More than 50 000 coconuts are needed to make 1 kg of silk
– To feed 25 worms from an egg to the flu stage you need a 10-foot mulberry tree or two small shrubs to provide enough leaves.
– The caterpillar increases its size 10,000 times before it is ready to spin its cocoon. A small branch will probably last a week and it takes four weeks for the silkworm to develop before it can develop into a cocoon.
