Egg Stage	Larva Stage	Pupa Stage	Adult Stage

___________________________________________________

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.
