Yellow-underwing Moth (Noctua pronuba): Introduced species that has spread across North America. First reported in Alaska from Haines in 2005. Present in Sitka, and presumably elsewhere in the region, by Summer 2006. Despite highly variable coloration, this species is distinctive due to its size and shape, as well as the orange-yellow hind wings. Flies from July through September.

Local Notes

  • Sitka/Noctua pronuba: Easily found around town during season when adults are present. Seems to be most abundant in August in many years. (edit)
