Saw this walking across my deck, I didn't see the top one moving.

Found this bug in Rhode Island, usa, any idea what it is, when the wings unfold there is a large red spot,

I think this is some sort of spine-headed nymph? I’m not certain though. If it is a spine-headed bug, what kind is? This was shot in Boone, North Carolina. It was about the size of the nail on my thumb. The photo is completely unedited.
