1. What is a pupa?A pupa is the stage between a caterpillar and a butterfly. It looks like a sleepy cocoon or chrysalis. Inside, the insect is changing into its adult form.
2. How does a caterpillar become a butterfly inside a pupa?Inside the pupa, old larval tissues break down and new adult parts grow from special cells called imaginal discs. Hormones tell the body when to start and finish the changes, so the caterpillar becomes a butterfly.

Histolysis: The breakdown of larval tissues during metamorphosis, providing building blocks for adult structures.
Histogenesis: The formation of new adult tissues and organs from imaginal discs and undifferentiated cells.
Imaginal Discs: Pre-programmed clusters of cells in larvae that develop into specific adult body parts.
Ecdysteroids: A class of steroid hormones that regulate molting and metamorphosis in insects.
