Type locality: St. Martin’s Falls, Albany River, Hudson Bay, [Ontario, Canada]. <i>Anarta bohemani</i>: <b>holotype</b> ♁ [ZMHB, not examined]. Type locality: Lapland. <b>Diagnosis.</b> <i>Lasionycta secedens</i> is easily identified without dissection by the combination of dark-gray to black-gray forewing and vivid yellow hindwing with black along the costal and distal margins. <i>Lasionycta leucocycla albertensis</i> (McDunnough) and <i>L</i>. <i>illima</i> sp. n. that also have yellowish hindwings lack black on the costa. <i>Lasionycta secedens</i> is the only <i>Lasionycta</i> in which the male lacks a postsaccular flap and the female has a strongly spiraled appendix bursae. <b>Distribution and biology.</b> <i>Lasionycta secedens</i> is Holarctic. North American populations are distributed from Labrador, northern Manitoba, and Alaska southward to northern Maine, northern Minnesota, and south-central British Columbia. It is found in boreal forest, especially bogs, and is both diurnal and nocturnal. Ahola and Silvonen (2008) report that early instar larvae prefer to feed on the epidermis of leaves of <i>Vaccinium vitis-idaea</i> L. (Ericaceae), but is polyphagous when reared. In Scandinavia the larva overwinters twice. In Minnesota this species occurs in raised bogs with <i>V</i>. <i>vitis-idaea</i> (K. Johnson pers. comm.) suggesting that this is the foodplant in North America. <b>Geographical variation.</b> Populations of <i>L</i>. <i>secedens</i> are arranged in two subspecies.
