I encountered this moth on Friday, April 25 at the Scherman-Hoffman Sanctuary. I thought it was a butterfly at first. I was hoping for a Compton Tortoiseshell. When it landed on the trunk of a tree, I realized it was a moth. I thought it might be a Tulip-Tree Beauty, because it was on a tulip tree. Unfortunately, the photo is garbage. I'll post it to bugguide.net and see what they think. Any thoughts from the readers out there?
