Well, I didn't get to witness it, but one of the butterflies emerged yesterday (Tuesday, August 24) I think it is a female, but I'm not certain. It flew off and landed in the grass, just long enough for me to get a couple of pictures, then off it went. I'm still waiting for the other one to emerge. Maybe I'll get to witness that one.
We also found a chrysalis on the side of our garage. I'll be watching that one too.
