Amazing Transformation of a caterpillar to butterfly

My lovely mother is a 3rd grade elementary teacher.  Every year she goes on caterpillar hunts to find those special little ones that live near milk weed plants to take into her classroom. The kids as well as everyone around are always amazed at how the cycle of life for these little creatures goes from egg to caterpillar to chrysalis and then to butterfly.  Bryan and I adopted a couple to watch first hand.  It was so amazing! This was our first baby!
