Two of three black swallowtails have emerged and a spicebush swallowtail still growing

First of three June 2008 Black Swallowtails 
The first of our three black swallowtail emerged sometime this morning while we were out running errrands. It wasn't quite ready to fly so we each got to hold it for a little bit, though by the time it was handed to Jonathan it was about to fly and spent more time on his head than his hand. The next picture is the second, emerged this afternoon. Still with much munching to do is a spicebush swallowtail caterpillar that i found enjoying my sassafras. I expect it to go green any day now.
