It is found from northern Washington and south-western Alberta northward to south-western Yukon. It is found in the alpine tundra. Adults are predominantly nocturnal but also fly during the day and feed on nectar of Silene acaulis. The wingspan is about 27 mm. Adults are on wing from mid-July to mid-August. A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described.
