Blue - Plebejus lupini

Blue - Plebejus lupini
Lovell Gulch, Teller County, Colorado, USA
June 7, 2010
Unfortunately, I couldn't get a shot of the underside. I think this is either Acmon or Lupine Blue. My field guide shows the Acmon as the most widespread, including Colorado, while BG suggests the opposite is true. Is it possible to tell which this is?

ID
There is some dispute which species the individuals in Colorado belongs to. Bugguide follows the viewpoint that this is Plebejus lupini. This is subspecies lutzi.

 
Thanks, Mike!
