The top photo makes me happy, because that tiny critter is an El Segundo blue butterfly, which is on the Federal Endangered Species list. He has been on that list since about the beginning of the Endangered Species list. Turns out, if you give the guy just enough of a certain milkweed, he'll be happy to come back. I think the bottom one may be an El Segundo blue, maybe ... If you know, tell me. At any rate, This habitat for flutterby-ity project is simple and nonetheless an amazing success story.
