Amazon has the Live Butterfly Pavilion for $21.11
You send off for the catepillars, they come in a small plastic container with the food they need. You watch the catepillars grow bigger and become chrysalids. And then in a week (yesterday for us), we watched them emerge. Truly amazing:) Now we will enjoy them for a few days and set them free in our garden.
Here are a couple of pictures of my daughter holding her new butterflies (She has named each of them of course). She is a happy girl!
