Anarta leucocycla var. moeschleri Staudinger, 1901; in Staudinger and Rebel 1901: 219.
Lasionycta l. moeschleri (Staudinger) occurs in eastern Canada from the east coast of Hudson Bay and southern Labrador north to the arctic islands near the Ungava Peninsula, Quebec. It is similar to subspecies leucocycla but has a more crisply marked dark-gray to black forewing with pale better defined orbicular and reniform spots and a purer white hindwing. Subspecies moeschleri is most similar to L. staudingeri of all L. leucocycla due to its white hindwing color. Th ey are sympatric on Baffin Island. Differences between them are given in the key and L. leucocycla Diagnosis section.
