Its a little challenging only seeing the underside but I believe post #1 is a polyphemus moth. Its is a widspread giant silkworm moth. That one is a male and looks freshly out of its cocoon. Lives for less than a week as an adult moth. Good find.
Post #2 is a cercropia moth. Another giant silkworm moth but slightly larger, different diets and brooding. Also a good find.
Both have reduced or no mouth parts so they are harmless. I think the cercropia does not even have a digestive system as an adult.
You can actually draw both of these to lights at night with some special techniques. My boys liked doing this when young and I will admit that I also think they have some cool colors/shapes on the wings/body.
