Lasionycta luteola
Lasionycta luteola is a small noctuid moth with a wingspan of approximately 27 mm. It inhabits alpine tundra environments in northwestern North America, ranging from northern Washington and southwestern Alberta northward to southwestern Yukon. Adults are active from mid-July to mid-August and exhibit a distinctive activity pattern: while predominantly nocturnal, they also fly during daylight hours. The species has been observed feeding on nectar of Silene acaulis, a cushion-forming alpine plant.
