Paonias excaecata, the 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.

Adult moths are nocturnal; after a brief bout of activity after dusk, they seem to prefer the later hours of the night.

Primary food sources for the larvae are deciduous trees such as willows, birch and cherries, as well as shrubberies, like ninebark and roses.

[3] Like the rest of the family Sphingidae, they burrow shallowly into soil to pupate.
