Life cycle of a Butterfly

Egg Stage
  • The female butterfly lays an egg on a plant.
Larva Stage
  • The egg hatches and the larva (caterpillar) comes out.
Pupa Stage
  • The caterpillar feeds on the plant and grows. When its skin becomes too small, the old skin splits open and the caterpillar pops out with a new skin on. This happens four or five times. When the caterpillar is fully grown it makes a little silk pad on a leaf or twig and attaches itself to it. The caterpillar's skin splits for the last time. It is now in the pupa stage.
  • Under the skin is the chrysalis. Many changes happen to the chrysalis. The wings, legs and rest of the butterfly are formed inside the chrysalis.

Adult Stage
  • The last stage is the adult stage when the chrysalis splits and the butterfly comes out.
