Lasionycta silacea
Lasionycta silacea is a noctuid moth described by Crabo & Lafontaine in 2009 as part of a major revision of the genus Lasionycta. It inhabits high-elevation coniferous forests near the treeline in the Pacific Northwest and adjacent Rocky Mountains. The species is nocturnal and has a relatively restricted geographic range spanning from the British Columbia Coast Range and Washington Cascades to extreme southwestern Alberta.
