I guess I've finally got to the place where I have photo'd so many moths, that I just can't think back and remember them. I thought I should recognize it--it looked familiar, and I looked through the saturniid moths at MPG (obviously not closely enough), but didn't look through my own file of my own images.The specimen I posted before is a dead ringer for this one. I think they are photo'd only days apart, so it's possible it's the same beast. Anyway, thanks much for the ID...

The photo of the one I just posted was taken on the evening of 29 August, and the one you found in the archives was taken on the morning of 30 August. I remember I got home after that trip and was excited by some moths new to me (this one included) and I posted them here right away. Now, a couple of months later, I'm working my way through my backlog of images, and today I was working on 29 Aug. Most embarrassing, I'll try to do better.

The lighting and background is different, so I wasn't sure. If you know that these are both shots of one specimen, please link the images. If not, keep them separate.

Side by side, the images look different enough for it to be different moths, but every single marking is identical--they are the same moth and it is lighting, exposure and a slight difference in composition that are creating the differences.
