I would greatly appreciate an ID on these moths. The one looked like a cecropia, but I wasn’t sure. I know that patterns can vary considerably depending on location. Thank you!

Of the three species of moths in the genus Callosamia, we believe your specimen is a female Promethea Moth, Callosamia promethea, also called a Spicebush Silkmoth. We are basing this on a photo posted to BugGuide. Our second choice would be a female Tulip Tree Silkmoth, Callosamia angulifera, also posted to BugGuide. We will tackle your second moth separately.
