Well our butterfly are all grown up and they have ventured out into the world on their own. We let them go on Wednesday and they were anxious to get out and discover the world. We were lucky that they left one at a time so that we could watch them just a little bit longer. Out of 5 caterpillars - 4 turned into butterflies. The last one stayed in his cocoon. I'm going to put that in a small jar and add it to ur science center.
