Cinda, those look like one of the Azure butterflies to me. That must have been awesome to see!
Looks like the butterflies are really showing up for everyone! I just released the male Black ST that came out late yesterday. He was raring to go and made a few laps before settling high up in the oak tree. I had another male Black ST come out sometime while I was asleep. He doesn't look ready to fly yet so I'm going to wait until the sun comes out a little more and then release him.
