Silkworm Life Cycle
We get silk from this beautiful creature called the silk worm.
Let's see how the life cycle of the silk worm helps us get this beautiful product called silk.
At first, the female silk moth lays eggs. When the
eggs hatch, a tiny caterpillar crawls out. This is
the silkworm or larva.
The silkworm feeds on leaves and grows.
When it is ready to enter the
next stage in its life cycle, it first weaves a net
to hold itself.
It then secretes a fibre made of protein, which hardens on exposure to air. This is the silk fibre.
It covers itself completely with this fibre, to form a cocoon. At this stage, the larva is called a pupa.
The pupa grows and changes
inside the cocoon. A few weeks later the cocoon
opens and an adult moth comes out.
The silk yarn is obtained from the cocoon of the silkworm.
