Have you ever wondered from where those beautiful silk sarees are made? They are made from silk which is obtained from silkworms. In order to understand the method of obtaining silk from silkworm, it is essential to understand the lifecycle of a silkworm. In this video, we will be learning about the lifecycle of a silkworm. The lifecycle of silkworm starts when a female silk moth lays its eggs on the leaves of a mulberry tree. These eggs then hatch into larvae. These larvae are known as caterpillars. The caterpillars are voracious eaters; they keep munching on the mulberry leaves for days together and grow in size. This stage is followed by the pupal stage, where the caterpillars weave a layer of silk around their body and get enclosed by it. This structure is called the pupa. The layer of silk surrounding the pupa is known as the cocoon. The pupa is the one from which we get silk. The pupa then develops inside the cocoon and emerges as an adult by breaking open the cocoon.
