Sagebrush Checkerspot --- Chlosyne acastus ?? - Phyciodes tharos - female

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?

Sagebrush Checkerspot --- Chlosyne acastus ?? - Phyciodes tharos
Definitely a Phyciodes in the tharos group. It's a female, which makes it more difficult. It is going to be either P. tharos or P. cocyta. Not sure if P. tharos makes it to Cody, but it looks more like that species to me. Thoros tends to be in the lowlands near rivers, in agricultural lands etc. and is usually multi-brooded (your date favors a 2nd or 3rd brood of P. tharos too). P. cocyta more up in the mountains, and just one brood that usually peaks in late spring to early summer.

This image
is almost identical to the photo of Phyciodes tharos in Glassberg's "Butterflies through Binoculars - The West". Not a Mylitta and not a Northern as depicted by Glassberg.
I will move it to the tharos page

Pearl Crescent?
I'm a novice, but this one looks familiar. See

 
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.
