What is a butterfly?

• Butterflies are not born exactly how they look.
  They undergo a very big change.
• There are three stages they must undergo before
  becoming a butterfly.

The Egg

• A butterfly starts its life as an egg, often laid
  on a leaf.

4
The Larva

• The larva (caterpillar) hatches from an egg and
  eats leaves or flowers almost constantly.
• The caterpillar molts (loses its old skin) many
  times as it grows. The caterpillar will increase
  up to several times in size before pupating.

5
The Pupa (Cocoon)

• The caterpillar turns into a pupa. The pupa is a
  cocoon or chrysalis.
• This is its resting stage.

6
The Butterfly

• At the end of the resting stage a beautiful,
  flying adult emerges.
• It is a butterfly!

The Anatomy

  basic parts
