|From the side.|
You can tell by the little dot on the middle of the wing that it was a female. Males don't have that, and they are more brightly colored. The weird thing was that after awhile, it just didn't want to leave. So I encouraged it to fly away by dropping it (that's what you do with birds after they're banded!), but it wouldn't go! So, after ten minutes or so, I finally got it to fly off. It was pretty cool - You don't get to hold Cloudless Sulphurs every day!
