Silvery Checkerspot?

Saturday
The forecast promised us quite a pleasant day, with sunshine and relatively low humidity, so we made the most of it, and packed up a picnic, and drove for about 1 3/4 hours to Clifty Falls State Park, near Madison Indiana. We got there about 11.30 ish, so we decided to do a hike before lunch. "Clifty Falls and the nearby Ohio River are products of the Ice Age. The Ohio River is a trench cut by sand and gravel laden melt waters of the glacial ice mass and basically marks the southern most advance of the glaciers which came from the north. Clifty Falls and its canyon are a subsequent erosion feature. From the lip of Clifty Falls, Clifty Creek plunges down more than 70 feet. In nearly three miles of canyon, the creek descends another 250 feet to the Ohio River below." There are four waterfalls and several other minor ones in the park. Summer, however, is not the best time to see the waterfalls, as the creek is reduced to not much more than a trickle, but there is still some good hiking, some of it quite rugged. Having hiked for about 90 minutes, we returned to the car and enjoyed our picnic at one of the picnic tables. Then we got our camping chairs out of the boot/trunk and sat enjoying the sunshine and reading for a while, before hitting the trails again. For my blip, since there wasn't much water in the waterfalls, I finally chose this beautiful butterfly - I believe I'm right in my identification as a Silvery Checkerspot, but I'm open to correction, if anyone can help me out, as I'm certainly no butterfly expert!
