Th e original description is suffi cient to characterize the species ( Lafontaine and Kononenko 1988). Type locality: Lapland.</p> <p> <b> Diagnosis.</b> <i> Lasionycta skraelingia</i> is distinguished from<i> L</i>.<i> taigata</i> Lafontaine by its undulating antemedial line (irregular in<i> L</i>.<i> taigata</i>) and more even gray forewing (mottled in<i> L</i>.<i> taigata</i>). The cucullus of the male valve is larger in<i> L</i>.<i> skraelingia</i> than in<i> L</i>.<i> taigata</i>, and the digitus is very short. Th e female genitalia are similar, but the appendix bursae of<i> L</i>.<i> skraelingia</i> is shorter than that of<i> L</i>.<i> taigata</i>. Th e CO1 sequence of<i> L</i>.<i> skraelingia</i> is identical to one of several<i> L</i>.<i> taigata</i> haplotypes.</p> <p> <b> Distribution and biology.</b> <i> Lasionycta skraelingia</i> is Holarctic, occurring from Scandinavia to northwestern North America. In North America this species is known from three specimens from Windy Pass, Ogilvie Mountains, Yukon. Th e adults are crepuscular and fly rapidly over small spruces. Th ey are collected by hand netting, rarely if ever coming to a light. Dates are from late June to early July.</p> <p> In Scandinavia the species is polyphagous when reared and has been fed on<i> Betula nana</i> L. ( Betulaceae),<i> Polygonum aviculare</i> L. ( Polygonaceae), and<i> Vaccinium uligonosum</i> L. ( Ericaceae) ( Ahola and Silvonen 2008). Th ese authors report that Eurasian populations are biennial, likely also the case in North America. The Yukon specimens were been collected in two odd-numbered years.</p> </body> </html>
