Facts about How Butterflies Develop

Some of the most mysterious facts about butterflies have to do with how they grow and develop. The metamorphosis from caterpillar to butterfly is done in the hidden confines of a chrysalis and seems to be a mysterious process to most people. Some facts about their growth and development are:

  • Many caterpillars eat 27,000 times their own body weight before they are ready to enter the chrysalis.
  • In the pupa stage the caterpillar's body is turned to a gel-like liquid and the cells are broken down and reorganized.
  • Once a caterpillar hatches from the egg it will increase its size 30,000 times before it is ready for the pupa stage.
  • Chrysalises of certain butterflies can produce small sounds to frighten predators away.
  • Butterfly wings are hollow. Once they come out of the chrysalis they will hang upside down while the wings fill with fluid. By doing this they use gravity to help their wings become stiff. This process can take several hours.
