Question

Difference between cocoon and pupa

Answer 1

With moths and butterflies, the first stage is the ovum or egg, the second stage the larva (larval stage) or caterpillar, the third stage the pupa (pupal stage) and finally it becomes the imago or adult, usually termed the ‘butterfly’ or ‘moth’.

Moth caterpillars spin a silk cocoon around themselves to enter the pupal stage.

Most butterfly larvae, however, split open and then the inside forms a transparent skin or cuticle. This is called a chrysalis.
