Tried a Google search on winter moth and came up with Operophtera
brumata with a description like yours. A University of Massachusetts
page said it had spread from eastern Canada to western, as you said,
and then down to Washington, Oregon and New England.
But it is definitely not what I had, which local newspapers referred
to as a tent caterpillar outbreak. However, as I said, my "tents"
were like the fall webworm, while the heavy outbreak of adult moths
noted earlier definitely resembled the eastern tent caterpillar.
One other oddity - both the winter moth and fall webworm adults are
described as being attracted to lights, but not the adult of the
eastern tent caterpillar.
I definitely remember the "thump, thump, thump" of heavy moth bodies
hitting the windows at night when the lights were on. Daylight
confirmed that the moths were brown and thick-bodied, but the fall
webworm moth is described as pure white.
