Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Observation notes: Saw this butterfly flying by and landing on the ground. It was a warm, sunny day.

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.
