Field Notes
I put this tree band up before Thanksgiving break, and we didn't see much action until 11/26. There were quite a few moths at that point. Then 12/2 there were moths swarming the whole area. I went for a walk at night during a rain, and they were everywhere. The next day, we went out and took these photos.
Supporting Evidence
Photo of my evidence.
We set up traps on 11/22 and we checked them periodically. This photo was taken on 12/3. We counted approximately 800 on this tree. We know they are probably winter moths because this is when they start to emerge from the ground.

We know this is a female winter moth because it cannot fly and has short wing stubs.
Photo of my evidence.
The wingspan of this moth is about 1 inch, so we think it is a winter moth.
