A yellow beauty

I was spoiled for blip choices today: a frog on a lily pad, a killdeer, a female wood duck with a good reflection, and two butterflies. I finally settled on this butterfly because it is a new one to me. I don't know what it is and can't find my butterfly books at the moment, so if you recognize it, please tell me. I had a great walk in North Chagrin Reservation, which is how I came by a few keepers. You can see the other ones in my blog if you have the time.
