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.

Vaccinium is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other ericaceous plants, they are generally restricted to acidic soils.
Vaccinium vitis-idaea, the lingonberry, partridgeberry, mountain cranberry or cowberry, is a small evergreen shrub in the heath family Ericaceae, that bears edible fruit. It is native to boreal forest and Arctic tundra throughout the Northern Hemisphere, from Europe and Asia to North America. Lingonberries are picked in the wild and used to accompany a variety of dishes in Northern Baltoscandia, Russia, Canada and Alaska. Commercial cultivation is undertaken in the U.S. Pacific Northwest and in many other regions of the world.
Subularia aquatica is an aquatic plant in the family Brassicaceae which is known by the common name water awlwort. This is a small herb with awl-like leaves, and growing from a corm above a network of bright white roots. Tiny flowers, each only about a millimeter long, are borne on stalks. Flowers which rise above the surface of the water open, while those that remain submersed stay closed and self-pollinate. The seeds come inside tiny inflated pods. There are two varieties of water awlwort; S. a. var. aquatica is native to Eurasia and S. a. var. americana is native to northern North America. There may also be a Mexican subspecies. This plant grows in ponds, marshes, peat bogs, and other shallow, cold water bodies, often in gravel or sand.
