Caterpillars to Butterflies

My parents bought Ella a butterfly growing kit for Christmas. We had to wait until spring to order the caterpillars though so he had a long wait. She was SOO excited when the caterpillars came. They came in two jars and they grew unbeleivably fast! Then when they turned into cacoons, we transferred them into the tent and waited a few more days until they came out! We fed them for a few days and then released them. The whole process was really cool! Ella loved it!
