This is Hyalophora columbia, the Columbia silk moth. Found in Burleigh County, North Dakota. It's similar to a cecropia moth, and is in the same genus, but based on color and pattern, this is definitely not a cecropia. See notes in photo for identification marks.

Fantastic great big moth! He's a beauty! Too bad his wing got nipped - I wonder if that was from a narrow escape?

I was wondering the same thing zxgirl.
This is a fantastic shot!

Looks like a Cecropia moth to me See www.butterfliesandmoths.org/species?l=3281 It is not purple enough to be a Columbian. See www.butterfliesandmoths.org/species?l=3282

Make sure you're looking at the dorsal side of the wing, and not the ventral side, which is mostly what's visible in this shot. There is a lot of red on the inside of the postmedian line here. Cecropias are grey. I added notes. Also, your link displays a photo of Hyalophora columbia gloveri, the Glover's silk moth, a very purple subspecies, and is labeled as such in the photo. H. columbia is also red, but not quite as purple as H. columbia gloveri.
So basically I know my moth is Hyalophora, and that it isn't H. cecropia. I know that it's also not H. euryalus, which has red both before and after the PM line. I know that it looks like H. columbia, but that it could potentially be some other Hyalophora, depending on what they look like and where they live.

H. cecropia typically has red shading just beyond the outer border of the PM line. That feature is lacking here, making this Hyalophora columbia - Columbia Silkmoth.

Thanks, Kiwi. I just wasn't sure if there were maybe more species of Hyalophora here than I was aware of. The only two in that genus that I'm familiar with are cecropias and columbians, but I don't know how many are native here.

I got a shot of the same looking moth and thought it was a cecropia: bit.ly/Kn7179. I guess it's not.
