Coordinator notes: Correct ID. The author of the name wyomingo considers this an allochronic subspecies of Ridings' Satyr (N. ridingsii) as you can find the typical subspecies at some localities earlier in the year (June-July) where this satyr flies later in August-September. Each have different mate-location behaviors. Read more on this if you are interested at http://dspace.library.colostate.edu.
