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 many cells are broken down and reorganized, while some organs stay the same.
  • Once a caterpillar hatches from the egg, it can 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.
  • Once they come out of the chrysalis, the blood veins in the wings haven't filled with blood yet. The butterfly will hang upside down so the blood flows into the wings with the aid of gravity. This process can take several hours.
  • The waste leftover from the chrysalis stage is ejected from the anus before the butterfly first flies away. This foul-smelling red liquid is called meconium.
