caterpillars to butterflies

One experiment that we are doing is watching Caterpillars turn to butterflies. It is sooo amazing. Isaac received them in the mail about two weeks ago. We've watched them start off as these little tiny caterpillars to huge caterpillars. Now they have entered the pupil stage. The went up to the top of the container and are now hanging upside down. Some have already turned into Chrysallides. We will be moving them into their habitat shortly! It's going to be pretty exciting to see them break out of their caccoon and into a beautiful Monarch butterfly!
