It is found in boreal forest, especially bogs, and is both diurnal and nocturnal.

Early instar larvae prefer to feed on the epidermis of leaves of Vaccinium vitis-idaea, but is polyphagous when reared. In Scandinavia the larva overwinters twice. In Minnesota this species occurs in raised bogs with Vaccinium vitis-idaea suggesting that this is the foodplant in North America.
