just noticed later in my photos as I'm uploading the Ulmus americana observation:

On birch.
One of two. Never seen before, and I handled them in an effort to be able to see the smudgy gray areas in the underwing. As I read down about the details about the species I noticed the last paragraph. The palm of my left hand has already began to itch. LOL
