A pupa is a stage in the life cycle of certain insects, such as butterflies or moths. It is a protective cocoon or casing where the insect undergoes metamorphosis and transforms into its adult form. For example, a caterpillar spins a cocoon around itself and becomes a pupa before it emerges as a butterfly. The word pupa would be used in this context to refer to the stage of development where the insect is inside the cocoon or casing.
