My brother-in-law has been studying insects all his work life since he got his BS in Entomology from U. Delaware in 1975. (Mostly Mayflies, but is very familiar with our NE moths). Here is an hour long video of aquatic insects he is featured in: https://youtu.be/GPBXi4N-hyU I sent him the photos and he does not think it is an Exyra. Man, do I wish I saved that moth to send him. I'll be keeping my eyes open next spring and remembering the smoke idea.
