they spin it so they can become a butterfly and being a butterfly is their way of browing up in life
A silkworm is a type of caterpillar. It takes a silkworm about three days to spin its cocoon around themselves. They use one long thread to spin the cocoon and if it is disturbed, the silkworm must start over.
The oldest caterpillar in the world was eating and trying to get big enough to spin a cocoon that I became 1 year old! Normally it takes 2 weeks to change!
The caterpillar makes a cocoon to complete the metamorphosis and turn in to a moth, butterflies make a chrysalis.
They lay eggs on Brassicas and their caterpillars will hatch and eat the leaves. Eventually, the caterpillar will spin a cocoon from inside which an adult butterfly will emerge.

Cocoon
The casing spun of silk by a caterpillar is called a cocoon. The caterpillar uses its silk glands to produce the silk thread and constructs the cocoon to protect itself during the pupal stage of its life cycle. The silk cocoon serves as a safe environment for the caterpillar to undergo metamorphosis and emerge as an adult moth or butterfly.
