Coordinator notes: There is no doubt this is a male Edwards Fritillary, Speyeria edwardsii. You can check this website for pictures of the Aphrodite Fritillary and compare the underside of it to your specimen. Usually the disc on the underside of the hindwings (where the silver spot are) is greenish on most edwardsii. Yours look quite more brownish but that may just be the lighting in the picture. If there is no upperside photo you can note that on your specimen of Edwards Fritillary it has a nearly solid black outer wing margin (or border) on the forewings. Yours is not quite so solid but more so than typical of any Aprhodite Fritillary.
