What changes have the caterpillars undergone? Tell me your reasons.

The caterpillar is just a caterpillar at first, and then it will become a pupa after a period of time. After this pupa lasts for a period of time, it will become a very beautiful butterfly.

The butterfly in larval stage is a small bug, which feeds on leaves and often perches behind them. As the larvae grow up day by day, the small skin can't bear the big body, so it falls off. Every time the larvae shed their skin, they sleep, which is equivalent to growing one year. In larval stage, they have to go through this molting for four times, and after four molting, they will obviously see that the body has grown up.

Growth experience

After growing up, the larva will spin silk and form cocoons, wrap itself in it, and then slowly become a pupa. Soon, the larva will complete metamorphosis, break the cocoon into a butterfly, and after coming out of the pupa, it will complete metamorphosis and become a butterfly.

The butterfly is the adult stage of the caterpillar, and its life habit and shape are completely different from those of the larva stage. With beautiful wings, it can fly freely in the sky, but it can't be as low as a bird. Since then, a small caterpillar has completed its transformation.

After becoming a butterfly, it will mate, and after mating, it will lay eggs, and then the eggs will develop into larvae, and this cycle will continue to breed offspring and extend life.
