Response Statement - Mottled Duskywing, Boreal population
This butterfly is declining throughout its North American range. In Canada, this particular population is restricted to a small area of pine woodland in southeastern Manitoba. All locations are under threat. One location is predicted to become flooded within ten years and the other four are expected to experience substantial population declines due to natural forest succession. The species’ habitat at all locations is at risk of Btk spraying to control Gypsy Moth. Any currently undocumented sites are likely to be experiencing a similar range of threats.
