In which sequence does the pupa develop in the life cycle of a butterfly?

The life cycle of a butterfly consists of four main stages: egg, larva (caterpillar), pupa (chrysalis), and adult butterfly. Each of these stages is critical for the butterfly's development.

Initially, the egg hatches into a caterpillar, which is the larval stage where the butterfly primarily feeds and grows. After a period of eating and maturing, the caterpillar then enters the next stage of development, transforming into the pupa, which is often referred to as a chrysalis. During this stage, the caterpillar undergoes a remarkable transformation where it reorganizes into a butterfly.

Finally, from the pupa, an adult butterfly emerges, completing the life cycle. This sequential progression indicates that all stages mentioned are integral parts of the butterfly's development, confirming that the complete sequence of development is accurately represented in the answer provided. Each step is a fundamental aspect of a butterfly's metamorphosis.
