This is certainly from Platyptilia or one of the closely related genera. The form of the labial palpi and the fact that the moth does not show two large scale-teeth projecting from each wing pair probably rule out Acanthodactyla. Anstenoptilia marmorodactyla looks close, but the forewing pattern is not quite right. Platyptilia williamsii looks by far the best fit among the Moth Photographers Group photos, although my impression is that the relative widths of the two forewing lobes don't look quite right for most Platyptilia species (I'd expect a broader second lobe) and the image of a live moth on the Moth Photographers Group page has a much plainer second forewing lobe. Otherwise, could this actually be a Paraplatyptilia species? Paraplatyptilia auriga looks a plausible fit but is excluded as an eastern species. There are many North American species in this genus (see http://www.plumemoth.com/) and few are illustrated by the Moth Photographers Group (http://mothphotographersgroup.msstate.edu/species.php?hodges=6109) or by BOLD (http://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=6693).

Thank you Donald for your detailed explanation. I saw he moth was on the window of my apartment in the morning and I didn't have time to take a better picture. By the the time I came back in the evening it was gone.
