Lasionycta leucocycla is a small (forewing length 10–12 mm, males; 11–14 mm, females) widespread species from the arctic, subarctic, and northern Cordillera. It has a narrow biserrate male antenna, a dark-gray or gray-brown forewing with a pale ocellate orbicular spot, off-white to yellow hindwing, and the ventral hindwing postmedial line is faint or absent. The male and female genitalia of L. leucocycla are typical for the species group and are of limited use for diagnosis. All L. leucocycla from east of Hudson Bay are distinguished from L. flanda, which occurs in Newfoundland and Labrador, by the white hindwings and ellipsoid eyes (hindwing yellow brown ...
