Thank you all.

I really appreciate all the help identifying this.

Interesting

I too would say Hyalophora columbia gloveri. However, if this is gloveri, this would represent a new record, and possibly a range extension as I was unaware of their occurence in southeastern NV.

Hyalophora columbia gloveri

This species is scattered across the Great Basin and pops up regularly in areas with adequate habitat and vegetation.

Higher elevations in SE. Nevada [Mount Charleston being the highest elevation at 11,918 ft (3633 m)], are not unlikely places to encounter this species.

You KNOW I DO ;)

Usually by the time gloveri are 5th instars, the scoli are a muted yellow or pale orangish-yellow.

It looks to be a 4th instar (red scoli).....the reds of the scoli are quite vivid in this specimen (so based on that, it may look to have a bit of a kaslo to it, but this critter would be a 100% "pure gloveri").
