The second one is a male Polyphemus Moth (Antheraea polyphemus)

#1 possibly Schinia florida, the primrose moth, but I can't find any pix with wings nearly lacking any pink such as your moth. The pink legs, furry thorax, wing shape all fit.
The traces of wing pink I see do fit the pattern.

Do you have any primroses around?

Being in Missouri...I am sure there are Primroses around...wonder if he is a freak of nature that isn't going to match the pink on the flowers.
Was wondering about the little side piece on the edges of the wings...didn't see that on the Schinia...
He stayed by my light for two nights, but is gone this morning...was going to check his underside.

In your photos there is a pink diagonal starting from the FW tip and the main leading FW vein is pinkish.

This is the piece I was wondering about...I didn't see it in any of the images of Schinia florida when I Googled it...is it insignificant?

It's part of the hindwing; insignificant in this case.

Ok...thanks!!

Oh my goodness that large moth is gorgeous! How lucky you are to have seen it up close!!
