Looks like a gossamer wing butterfly
Western butterflies are tough for me and specimen appears faded and worn but this one looks similar to Satyrium semiluna - Sagebrush Sooty Hairstreak. Although this location is not indicated in some guides, it is a resident based upon the numerous images from nearby Grand county CO. in Butterflies of America http://butterfliesofamerica.com/t/Satyrium_semiluna_a.htm

It's a tough angle but it looks like Plebejus glandon

I agree. Don't know how I missed your ID.
Reviewed several blues and for poor reasoning got off track. The low profile of the forewing makes this a tough ID.

I'm not an expert,
but clubs at the end of antennae indicate it's a butterfly.
I am not familiar with Western butterflies.

I think you are right Nancy. Thanks!
