Plebejus - Moved
I also vote for Plebejus; assuming that is correct:

Going by Glassberg,(1) I would have said Acmon.

Going by Pyle,(2) both Acmon and Lupine are likely and difficult to differentiate.

Moved from Blues, Coppers, Hairstreaks, Harvesters.

Moved
Moved from ID Request.

Acmon Blue?
I don't know most of the western blues very well, but could this be a male Acmon Blue, Plebejus acmon?

 
Plebejus
It certainly looks like a Plebejus species, I will look into that more. Thanks!
