Amazon has a great deal on a Live Butterfly Garden. Currently is is just $12.34 (reg. $25) and it ships for free with Amazon Prime! You can order the garden now and then wait to order the larvae until your weather is warm (spring/ summer for most people or now if you live down south).
When you receive your kit, you will also be given a certificate to go online and order your larvae for when you want them. The certificate allows you to get them for free, but you do have to pay a small amount for shipping. I think this makes a great “science experiment” for kids and is a great way to teach them during the summer when they are out of school.
