How do silkworms make cocoons?

• The silk used by humans comes from the domesticated silkworm, Bombyx mori.
• Silkworm moths begin their life as an egg that then hatches into a growing, feeding caterpillar.
• When a silkworm has eaten enough, it constructs a cocoon made out of silk fibres, and inside that cocoon, it turns into a pupa.
• After many days, a fully formed adult silkworm moth emerges through a spit-soaked opening in the bottom of a cocoon.
