A friend of ours has a place in Tatamagouche, Nova Scotia (opposite the Eastern tip of Prince Edward Island). Here is a picture of the moth. On of our field biologists and Biosphere (Bras d’Or Lake Biosphere Reserve Association) directors identified it as a type of Hawk Moth. But from all of my readings these moths are basically nocturnal yet it came to them in the middle of the day.

This beauty is a One Eyed Sphinx or Cerisy’s Sphinx, Smerinthus cerisyi, and your image wonderfully illustrates the illusion of a large predator created when the moth flashes the eyespots on its underwings. According to Sphingidae of the Americas: ” Here on Prince Edward Island, Cerisy’s Sphinx is one of the earliest Sphingidae (both male and female) to come in to lights, with most appearances occuring [sic] from early June to mid July from 10:00 – 11:30 pm. When we have an early spring, this moth can be taken as early as mid May.” We don’t know why this individual was flying during the day.
According to David Harris (at Cape Breton University) these types of moths (he didn’t classify as neatly as you did) in the Springtime seem to get ‘confused’ and will come out during the day.
