No Alberta data: elsewhere reported larval hosts include Large-tooth aspen (Populus grandidenata), willow (Salix) and cherry (Prunus) (Rockburne and Lafontaine 1996). Prentice lists single larval host records for four tree species; tamarack (Larix), Red pine (Pinus), poplar (Populus) and white birch (Betula papyrifera).
Range
Nova Scotia to British Columbia, but apparently rare everywhere. In Alberta it has been collected in the dunes southeast Edgerton and in the Red Deer River valley north of Jenner.
