We just found both of these in our yard in CT. Both silkworm moths, we think a polyphemus and a prometheus–any thoughts. Both about 5” wing span.

We agree with both of your identifications. The Prometheus Moth is a female. The sexually dimorphic males are smaller and have very dark coloration. The Polyphemus Moth is also a female. The antennae of the male are much more developed.
