Alypia langtoni
Langton's Forester, Six-spotted Forester
Alypia langtoni, known as Langton's Forester or the Six-spotted Forester, is a diurnal moth in the family Noctuidae. First described by William Couper in 1865, this species exhibits sexual dimorphism in wing spotting pattern. Males possess eight white spots on black wings, while females have six. The species has a broad transcontinental distribution across North America, with larvae that feed on fireweed (Chamaenerion species). Adults are active during daylight hours, an unusual trait among noctuids.
