Life Cycles

• Butterflies and moths have a life cycle with four
  steps/stages
• An adult lays an egg
• The egg hatches an out comes the larva
  (caterpillar)
• The larva eats and grows and becomes a pupa
  (chrysalis)
• The pupa changes into an adult (butterfly)

10
Eggs

• Butterflies and Moths
• Very tiny (grain of salt)
• Laid underneath a leaf
• - Safe from sun, water, predators
• - The plant will act as food for the larvae
• Still very few eggs will grow into adults

11
Larva

• Most eggs hatch into larvae in 3-10 days
• Long bodies with six main parts
• Always eating
• - eats its shell
• - then eats leaves around them
• Outgrows its stiff exoskeleton
• New skin underneath that gets hard
• - this happens many times as the larvae grows

12
Pupa

• The biggest change
• Each larva forms a covering around itself (Pupa)
• Smooth surface
• Hang from leaves or twigs
• A butterfly pupa is called a chrysalis
• A moth pupa is called a cocoon
• Stage lasts for a week or two
• The pupa sheds its covering and now is an adult

Adults

• The flying moths and butterflies we see are
  adults
• They have stopped growing
• Most live only a short time
• - a few days or a few months
• Some eat nectar, tree sap or the juice from fruit

• The cycle continues
