When butterflies molt, they shed the exoskeleton and grow another one. There is no question that we need to preserve existing habitats, but we can also begin to reestablish habitats and increase diversity by integrating native plants into the landscape, both on a large scale and in our own backyards. Exploring the facets of different life cycles gives children a firmer grasp of how living things must exist together for the benefit of all. It is the Once the larva embeds a hook-like structure at its rear end into the button, the rest of the skin can slip off.
