The Mulberry Wing
This moth is not what it appears to be (unlike a Yellow-breasted Chat, which is what it appears not to be).  While looking very much like a geometer -- just like a White Spring Moth with spots or a decent fit for the genus Itame -- they is it's a member of the Drepanidae family. Those are the hooktips, with this being the only one of our species that doesn't have that characteristic to its forewings. It's a Northern  Eudeilinea (Eudeilinea herminiata) and it was a first record at Pound Ridge Reservation July 29.
