A chrysalis is the pupal stage of a butterfly.

- The life cycle of a butterfly consists of four stages: egg, larva (caterpillar), pupa (chrysalis), and adult.
- The egg is the first stage, where the female butterfly lays a tiny egg on a plant or leaf.
- The egg hatches into a larva, which is commonly known as a caterpillar. The caterpillar has a voracious appetite and spends most of its time feeding on leaves. It grows rapidly and sheds its skin several times during this stage.
- After the caterpillar reaches its full size, it enters the pupal stage. The pupa is also known as a chrysalis. This is a transformative stage where the caterpillar undergoes a remarkable change inside the chrysalis.
- Inside the chrysalis, the caterpillar's body breaks down and rearranges itself into a butterfly. This process is called metamorphosis. The caterpillar's tissues, organs, and even its entire body structure are completely transformed during this stage.
- The chrysalis provides a protective covering for the developing butterfly. It is usually attached to a plant or other surfaces, and its appearance can vary depending on the species of butterfly.
- Inside the chrysalis, the butterfly undergoes a complex series of changes. It forms new body parts, such as wings, legs, and antennae, and its internal systems develop. This process can take anywhere from a few days to several weeks, depending on the species.
- Once the butterfly has fully developed inside the chrysalis, it emerges as an adult butterfly. It breaks open the chrysalis and unfolds its wings, allowing them to dry and harden. The newly emerged butterfly then flies away, ready to begin its adult life and continue the cycle by laying eggs.

In summary, a chrysalis is the pupal stage of a butterfly, where the caterpillar undergoes metamorphosis and transforms into a fully developed adult butterfly.
