This pair of butterflies were found today on my backporch screen. I can’t identify them nor have I ever seen them before. They appear to be mating and they really haven’t moved in hours. Can you idetify them?

Mating Prometheus Moths

Dear thefootballref,
What a wonderful image of mating Prometheus Moths.  They exhibit pronounced sexual dimorphism, with the male being darker and smaller, and with a different wing shape.  BugGuide has an excellent profile of this Giant Silk Moth which is also called the Spicebush Silkmoth.
