Bests & Worsts Reviews from Amazon

I bought one of these last year for my nieces. I also got one for me, and I'm in my 30's. I waited until the spring time to send in my caterpillar certificate. They came in their own little container with just enough food. So you don't need to feed them anything. I tried to put some real food such as leaves from the plants they like to eat in the wild, but they preferred the food that came with them. I think I received 6 caterpillars and they all turned into butterflies. I let them go a day or two after they emerged. Kids are completely fascinated by the process from caterpillar to chrysalis to butterfly. One word of caution, it may not be the best thing to get for Christmas since you may have to wait until spring to get your caterpillars. They will send them in the winter, but I didn't want the butterflies to die on me or freeze to death if I let them go.
