We got butterflies from a company called Insect Lore, www.insectlore.com last Easter. We ordered the kit than came with a reusable butterfly sanctuary so we just order the larvae each year from now on. The kids really enjoyed watching the hatching process last year. We're going to do it again this year so that we can continue with the idea of new life. I appreciate the idea about featuring the growing butterflies during coffee hour, that's a great idea. I highly recommend this company for purchasing. They send everything ready for Easter release and they have good customer service and help.
