Ok, I found this in my driveway this morning.It was still alive and whatever Butterfly it was supposed to be it better hurry up and do it. I've never seen anything like it. I carried it all around the house this morning showing it to everybody much to their delight? It's now residing out in the prairie doing whatever it is they do.
NOTE: THANK YOU YVONNE who sent me the link: http://en.wikipedia.org/wiki/Eumorpha_pandorus to tell me what this is. Wow, isn't that amazing? I just love learning this stuff. THANK YOU SO MUCH, YVONNE!
