Butterflies and moths

 They undergo complete metamorphosis

 Female lays eggs mainly on the underside of the leaves

 Eggs hatch into larva / caterpillars which feed on leaves

 The larva spins a cocoon around itself and changes into

pupa/chrysalis which does not move or eat i.e. it is

dormant.

 When the adult is full grown, it breaks the pupa case and

comes out.
