Your moth is the Eight-spotted forester moth. Chimera you did know the genus, thanks! If you look at the hind wing I think there are 2 spots on each so it is the 8 not the 6 spotted.
Here is a website from Canada that compares three similar species of that genus. - http://www.cbif.gc.ca/spp_pages/noctuoidea/jpgs/image_e.php?image%5B%5D=109318.jpg%2CAlypia+langtoni&image%5B%5D=109314.jpg%2CAlypia+octomaculata&image%5B%5D=109319.jpg%2CAlypia+ridingsii
These moths are found over most of North America. The larvae feed on grapes, Ampelopsis spp. and Virginia creeper. So, they will be seen near woodlands and woodland edges. The moths feed on nectar from herbaceous plants and unlike most moths they do fly during the day.
There would be one generation in NE, bur has 2 generations in the south. They overwinter as pupa in the soil.
Here are photos of the caterpillar and adult moth - http://bugguide.net/node/view/485/bgimage
Alypia sp. Forester moth by: Chimera
Looks like an Alypia species, pehaps A. langtoni Six-spotted Forester Moth.
