Moved from Butterflies and Moths. A very distinctive moth that only had a couple of matches when going thru all of the MONA Fascicle 27-2 images. I think churchillensis is the best match based upon maculation, range and the fact that this species is purely diurnal. See page 45 and images 51-53 on Plate 1 of the fascicle linked at Moth Photographers Group. I might even go as far to say that this appears to be the subspecies churchillensis churchillensis based upon the AM and PM lines as described for this subspecies in the fascicle. Although the location where this moth was found is sort of between the known range of the two subspecies, I think maybe this sighting begins to fill in a possible gap in collection.

my final answer...
Hold the bus! I am glad that something clicked in my brain about what Fascicle 27-2 says about species that may be confused with churchillensis. I went back to the fascicle and there are two more diurnal species in the Euxoa Orosagrotis subgenus that need to be considered - Euxoa nomas incognita and Euxoa montana. Euxoa montana appears to be limited to Colorado and Wyoming. Whereas the range for nomas incognita is right in the area this moth was found. So, let me redirect to page 149 and images 33-34 on Plate 8 of the fascicle. The images within the fascicle do not match up well with this moth, however one of images at BOLD for this species is almost a perfect match. So, I am now going to move to the subgenus Orosagrotis, and if there is agreement on this, we will have to create a new group and species page for BugGuide.

This one below is very close, but I'm not sure that they are the same species. It's a very big and complicated genus.
