The worm-like larva grows inside the egg. From this point on, the monarch drinks all of its food. It looks different in all its stages and, therefore, it is called 'transformation' and not 'growth'. In order for the larva to keep growing, molting must occur. Most children understand that they came from their mother, and apply the mammal style of reproduction to other living things.
