Paonias excaecatus (blinded sphinx) is a moth of the family Sphingidae. It is found in Nova Scotia, New Brunswick and Prince Edward Island, and across the rest of Canada all the way to British Columbia. In the United States it ranges south to Florida in the east, and westward to eastern California and as far south as central Texas. The wingspan is 60–85 mm. Adult moths are nocturnal; after a brief bout of activity after dusk, they seem to prefer the later hours of the night.
