Last month, many butterflies hatched on my lime trees. I have been looking through some of the You Tube videos to see how Butterflies transform – well, I have seen hundreds but they are still very interesting. The ones that grew on my two lime trees are now flying about in the yard which is wonderful to see. In this YouTube video, the complete life-cycle of the Monarch butterfly is shown from a tiny caterpillar hatching from an egg on a Milkweed leaf through metamorphosis to become a glorious adult butterfly. Filmed utilizing high-powered microscopic cameras and time-lapse photography. Produced for the Chicago Nature Museum in Chicago, IL.
