Caterpillars to cocoons

Our caterpillars have grown so much. They grew to the biggest, longest caterpillars we had seen. Then they climbed up to the top of the pot and hung down from the lid. The caterpillars then wrapped themselves up into cocoons, ready for the magic change to happen. The cocoons are now hanging in our butterfly garden and we will check every day to see when the butterflies emerge from the cocoons.
