Ecology

edit

The larvae feed on Ericaceae species, including Vaccinium vacillans and Ledum groenlandicum in the east. They feed on a wide variety of plants in the west, including Arbutus and Cuscuta species. They feed on the flowers and fruits of their host plant.

Pupation takes place in the litter at the base of the host plant. Hibernation takes place in the pupal stage.

The adult's wingspan is 22–29 mm. Adults are on wing from early May to early June in one generation.[5] They feed on flower nectar from various species, including Vaccinium, Sanicula arctopoides, Lindera, Salix, Barbarea and Prunus americana.
