Question

the exact sequence of life cycle of Silk worm​

Answer 1

The exact sequence of life cycle of Silk worm is - Egg,Larva,Pupa, Adult.

• A silk worm has several biological stages in it's whole life cycle.
• There are mainly four biological stages in the whole life cycle of the silk worm, which are egg,larva,pupa and adult. (written in sequence).
• Although, there are different sub-stages included in the four main biological stages of the whole life cycle of a silk moth.
• By completing all the life stages, the egg becomes an adult moth.

We have to write the life cycle of a Silkworm.

( See in the attachment how the egg,coccon etc looks like, Now I'm going to give by the stage. )

• Stage 1 - Egg
• Stage 2 - Silkworm
• Stage 3 - Cocoon
• Stage 4 - Pupa
• Stage 5 - Moth

( As you can see there are five stages. )

Stage 1: Egg

• An egg is the first stage of the life cycle of the silkworm. The egg is laid by a female moth which is mostly the size of small dots. A female moth lays more than 350 eggs at a time. In the springtime, the eggs hatch due to the warmth in the air. This procedure happens once in every year.

Stage 2: Silkworm

• A hairy silkworm arises after the eggs crack. In this stage of silkworms, the growth happens. they feed on mulberry leaves and consume a large amount of these leaves for around 30 days before going to the next stage.

Stage 3: Cocoon

• In this stage, silkworms spin a protective cocoon around itself. It is the size of a small cotton ball and is made of a single thread of silk.

Stage 4: Pupa

• The pupa stage is a motionless stage. In this stage, people kill the pupa by plunging the cocoon into boiling water and unwind the silk thread.

Stage 5: Moth

• In this stage, the pupa changes into an adult moth. The female moth lays eggs after mating and thus the life cycle of silkworm begins again.

If you haven't understand here is another Explaination.

• The life cycle of silk moth starts when a female silk moth lays eggs.
• The caterpillar or larvae are hatched from the eggs of the silk moth.
• The silkworms feed on mulberry leaves and give rise to pupa.
• In the pupa stage, a weave is netted around by the silkworm to hold itself.
• After that it swings its head, spinning a fibre made of a protein and becomes a silk fibre.
• Several caterpillars form a protective layer around pupa and this covering is known as the cocoon.
• The silk thread (yarn) is obtained from the silk moth’s cocoon.
