For Paul's birthday Grandma gave him a butterfly habitat along with a coupon to mail off for caterpillars. They arrived about two weeks ago and spent several days chomping through the food that came with them before they developed into chrysalis. A few days ago the butterflies emerged, which was very exciting. Today Paul reluctantly set them free. I know he was very sad to see them go, but I bet the butterflies are happier to be out in the world doing what butterflies do.
