Sunday afternoon, July 25, 2021 I heard back from the Butterfly identification team. If only I had taken prompt action at the time. Here is the email:

Subject: Re: Moth that emerged from cocoon today. Photo attached Hello,
It looks like a female Gypsy Moth and a cocoon for that same species. It is an invasive moth and huge pest, and it is found in your state. This year, northeastern states seem to be experiencing growth in the Gypsy Moth population.
Thank you for sharing your photos with us. The male looks different from the female and the faster it is identified, the better.

As noted in the first posting, I released the moth. I needed to take swift action last year: identify and remove egg clusters. This spring our legacy oaks, favored by Gypsy moths, were chewed up and the caterpillars, when landing on exposed skin, cause a nasty rash.
