The diagram represents the butterfly’s life cycle which consists of fours stages.

Butterfly begin life as eggs which are laid by adult butterflies after mating. Those eggs stay at the plant between two and three weeks and then develop into the embryo at their second stage of the lifecycle. During this stage, one embryo grows up to a caterpillar, before they enter the next step.

After about two months, a pupa will create by the caterpillar that completes the growth of skin-shedding. The shape of pupa does not remain for long, just around two hours, and the metamorphosis happens which means that the lifecycle goes into the final stage called Pupal stage. During the phase, the metamorphosis stays about two weeks, after which it becomes the adult butterfly.

The adult butterflies will mate with their counterpart and lay eggs on some plants, and then the cycle starts anew.

Answer

Here is a corrected version of your description of the life cycle of a butterfly:

The diagram represents the butterfly’s life cycle, which consists of fours stages.

The adult butterfly represents the first stage of the butterfly’s life cycle. The adult female butterfly lays eggs on the leaf of a plant after mating. The eggs  remain on the  leaf for two to three weeks, while the embryoes develop. The second stage of the life cycle is when the embryoes have developed into tiny caterpillars, which emerge from the eggs when they are ready.

Once the caterpillars are fully grown and have shed their skins several times, they start to turn into pupas.  This is the third stage of the life cycle.  The final stage of the life cycle is represented by the metamorphosis of the pupa into a new  butterfly, which emerges from the pupa once its wings are fully developed.  This metamorphosis takes about two weeks and is known as the pupal stage.

The adult butterflies mate  and lay eggs on  plants, and  the cycle starts anew.

Got it, my friend. I don't know the section is what to use for before.
Thank you so much.
