Field Notes
During the early evening we let the dogs in the house and a moth flew in with them. The moth landed and the ceiling and my boys commented that they were surprised to see a moth out when it was so cold. We looked at the moth and thought it looked a lot like a winter moth.
Supporting Evidence
Photo of my evidence.
The moth looked a lot like a picture of a winter moth. A lot of moths are small and brownish, but the moth we found had some dark fringe on the end of the wings and a few darker bands along the wings. The body was a bit lighter in color.

This moth may be either the invasive winter moth or the native Bruce spanworm. Both are flying now and the only way to tell the two apart is to dissect the moth. Please feel free to send the moth (or moths) to me in a ziplock bag in an envelope to:
