Caterpiller

OK, our little friend Macey was at our house last week. She is a BIG animal/nature girl, so leave it to her to find a chrysalis and/or caccoon. Of course when they were looking at it, it "fell" out of the tree. We had to save it, so we took it inside to an aquarium. It looked closed up when we first put it in, but now the caterpillar goes in and out of it and takes the chrysalis all over the place. So, our mommy friends are wondering what kind it is and what it is doing. If you have any expertise in this subject, please leave your comments and the rest of us will learn! Alex really likes checking on it daily to find out "where" it is! I'll keep you updated.
