This moth was outside our front door one morning, up in the alcove. Then a couple weeks later it was on our doorstep for the day. I assumed it was dead since it was on the ground, but poking it gently with a stick told me otherwise. It was gone once evening set in.
I used the site linked below to identify this moth. If you know more than I do, and I got it wrong, please let me know. I’ll be glad to update this post.
