Sagebrush Checkerspot --- Chlosyne acastus ?? - Phyciodes tharos - Female
Cody, Park County, Wyoming, USA
September 17, 2005
Size: 1 1/2 inch
Found in sagebrush country, 5200 ft elevation. The closest I could come in my guides is a Checkerspot. Although it says flies in spring and early summer. Maybe a second brood? -- Sorry, this is the only image I captured of the wings below.

Phyciodes mylitta?
The bottom teir of cells on the hind wing is "eyed" - unlike acastus. The Audubon guide book has a picture of Phycoides orseis that looks very similar but is not reported in your locale. Howe reports P. orseis and P. mylitta can be easily confused. P mylitta is widely distributed in the west so I would put my money there.

http://pick4.pick.uga.edu/mp/20q has a great picture. Use the search.

Crescent
I can see more clearly now. Thanks to Steve and Jim, they suggested Mylitta or Pearl Crescent. I do note the bottom teir of cells on the hind wing is "eyed" and antenna clubs appear orange, so I lean toward Mylitta Crescent -- Phyciodes mylitta. Wish I had a better image of below. Oh well, next time. Thanks to all.
