Creole Pearly-eye, Enodia creola, Weymouth Woods Sandhills Nature Preserve, Moore County, North Carolina.
The three Pearly-eyes are a bit difficult to identify. I believe I've gotten these correct. You can browse them at BugGuide.
Randy Emmitt has photos of this very same individual on this page. (Note the bit of fluff on the forewing.)
See also his Pearly-eye help page. Thanks Randy!
