I bought the Insect Lore Live Butterfly Garden for my son when he was in grade school. He loved watching the caterpillars grow (caterpillars are sent separately from the kit. Ours arrived quickly and in excellent condition), and watching them create cocoons when they were through eating leaves from our garden. The instructions to care for the caterpillars were easy to follow, giving my son a sense of accomplishment. When the butterflies hatched, we released them into our yard. This is the only drawback. I'm not sure that the species of butterfly that we were sent is native to our area. Of course we were going to release them but I am concerned about introducing non-native species.
