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.

Female Prometheus Moth

Hi Dee,
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.
