Last year we raised frogs from tadpoles... this year it was butterflies. If you are going to attempt butterflies, make sure you check your mail everyday. Our caterpillars sat in our box for a couple days... I don't think that it mattered, because I think that they sent us two caterpillars and three cocoons!
Oh well, in a matter of two weeks, the two caterpillars turned into cocoons and then butterflies. The whole process was fairly easy! We kept the butterflies for a couple days and released them out on the deck this evening. The boys loved it... especially Ethan. He's the kid who wants a bigger house so that he can get two more dogs and two more cats!
