Eyes are brown (when still alive); no dark spot (or occasionally just a trace) near base and lower margin of the front wing (other species in the east normally have a prominent spot there). Row of "postmedian" round spots on front wing large and prominent. Atlantis Fritillaries have gray eyes, and Aphrodite Fritillaries have little black edging along the veins of the upper front wings (this difference is most noticeable in males, and this individual is a female). There are lots of other subtle differences, and the under sides of Great Spangled Frits are quite different. It's hard to see in most photos, but Atlantis Fritillaries are usually much smaller than Great Spangled, and Aphrodites are somewhere in between (usually closer to Great Spangled).

Speyeria cybele ssp. cybele

I'm not an expert, but it looks like Atlantis Fritillary. It's a northern species.
