Butterfly Life Cycle

  1. 1. Life Cycle of the Butterfly Ms. Newcombe’s 3 nd Grade Class
  2. 2. <ul><li>Metamorphosis is another word for “change”. </li></ul><ul><li>When we study the life cycle of a butterfly, we are talking about the changes that take place from the time it is born, until it becomes a  </li></ul><ul><li>Life cycle, is not the same as life span. Life span is the length of time the butterfly lives. </li></ul><ul><li>Most butterflies have a short life span of only a few weeks. </li></ul>Metamorphosis beautiful butterfly
  3. 3. <ul><li>The very first stage of the butterfly life cycle begins with the eggs that the butterfly lays. </li></ul><ul><li>* The average number of reported eggs that a butterfly will lay is about 700. </li></ul><ul><li>* They only lay one egg at a time, but they can lay many in a single day. </li></ul><ul><li>* The eggs are about the size of a pinhead. </li></ul><ul><li>* The butterflies lay their eggs on the bottom of leaves where they will be protected. </li></ul>Laying Butterfly Eggs
  4. 4. <ul><li>The female butterfly will lay her eggs under a protective leaf that will later become her baby’s first meal. </li></ul><ul><li>The butterfly eggs will take about two to three weeks to hatch. </li></ul><ul><li>When the butterfly egg hatches, a caterpillar also known as, a larva will come out. </li></ul><ul><li>The caterpillar hatches through the egg by waving its head back and forth pulling its body out slowly. </li></ul>Stage One: The Egg
  5. 5. <ul><li>Caterpillars or larva are very tiny, and are usually a pale green color when they first hatch. </li></ul><ul><li>They have strong jaws for chewing leaves; </li></ul><ul><li>* Their own egg, is the caterpillars first meal </li></ul><ul><li>* After they eat their egg, they will eat the leaf that their mother had laid them on. </li></ul><ul><li>The caterpillar will eat about thirty or more leaves, and grow to 3000 times it original size, before the next stage of its life cycle. </li></ul>Stage Two: The Larva
  6. 6. <ul><li>Before “inching along” to the third stage of the life cycle, the caterpillar must go through a molting process: </li></ul><ul><li>1. it stops feeding </li></ul><ul><li>2. it spins a small silk pad; skin will start to split </li></ul><ul><li>3. it crawls forward leaving old skin behind </li></ul><ul><li>4. it starts feeding again, beginning with the nutrient filled skin they have just shed </li></ul><ul><li>The growing stage between molts is called an instar. </li></ul><ul><li>By the fourth molt the caterpillar is almost ready for stage three. </li></ul>Caterpillars: Inching Along
  7. 7. <ul><li>The caterpillar will: </li></ul><ul><li>Find a safe strong spot, like a leaf or twig, to hang from. </li></ul><ul><li>Start squirting silk, moving from side to side, creating a silk mat with a tiny knob called a button, the caterpillar will hang from this button after shedding its skin for the last time. </li></ul><ul><li>3. A hard case called the chrysalis forms around the caterpillar for protection while it is preparing to become a butterfly. </li></ul>Stage Three: The Pupa
  8. 8. <ul><li>Inside of the chrysalis the caterpillar or pupa, becomes a green liquid. </li></ul><ul><li>The green liquid begins to form butterfly parts and the chrysalis becomes more clear. </li></ul><ul><li>A fully clear chrysalis means a butterfly is ready to emerge : come out. </li></ul><ul><li>About three weeks later the chrysalis splits, and the butterfly can make its way out ……. </li></ul>Stage Four: The Chrysalis
  9. 9. Ta-Da! <ul><li>Now the butterfly is free to travel by air. </li></ul><ul><li>The butterfly will drink nectar, instead of chewing leaves. </li></ul><ul><li>Bad News: The average butterfly will only live for about two weeks… </li></ul><ul><li>Good News: Before the butterfly dies it will lay new eggs…out will come new caterpillars…and eventually… </li></ul><ul><li>new Butterflies </li></ul>
