  • Our topic for today is Life Cycle of a Butterfly.

  • A butterfly lays eggs on the leaves of a plant.

  • These eggs hatch and young ones called larvae or caterpillars come out of the eggs.

  • The caterpillar first feeds on the egg shell from which it is born.

  • It then starts feeding on the leaves and starts to grow.

  • The caterpillar sheds its skin several times so that it can grow.

  • Once the caterpillar is big enough, it stops eating.

  • It then forms a protective layer around itself.

  • This stage is called chrysalis.

  • In this stage, the caterpillar is now called pupa.

  • The pupa remains motionless in the chrysalis.

  • Inside the chrysalis, the pupa undergoes a series of changes.

  • After about 15 days, a beautiful adult butterfly emerges out of the chrysalis.

  • When the butterfly comes out, it's wings are small and wet.

  • The butterfly pumps fluids into its wings to make them strong and to expand.

  • After a few hours, the wings become strong enough and the butterfly is able to fly.

  • These series of changes in the life cycle of a butterfly is called metamorphosis.

  • The End.
