 Pohl et al. (2010) noted that the species was reported in Alberta by Prentice (1962) and Ferguson (1978) but they were unable to locate voucher specimens. According to Pohl et al. (2018) records from western Canada are confused with Orgyia antiqua, and there are no verified observations west of Manitoba (Canada). 
There are nevertheless reports of the pest for Saskatchewan and Alberta in Natural Resources Canada (2019).
