Coordinator notes: This is a female of the Mormon Fritillary. It had an exceptional flight everywhere in the higher forested areas of western Colorado. Aphrodite did also but it is more localized at lower altitude especially in the oak-zone just below the pine forests. One way you can tell Aphrodite from several other species is that it has brown eyes and not bluish-gray eyes (as you can see in your photo). Only it, the Great Spangled and Nokomis Fritillary have brown eyes in our area, all the other grayish-blue ones. Mike
