Abstract

Nine adult specimens of Aeshna subarctica, a boreal dragonfly typically associated with muskeg wetlands, were collected from Black Lake and Breitzman Lake in northwestern Wisconsin (Douglas County). Viable populations likely exist in both lakes. Oviposition by three females is described. This represents the first published report of A. subarctica for the state of Wisconsin. Because Black Lake lies on the border of Wisconsin and Minnesota, A. subarctica likely occurs in Minnesota as well. Further sampling of acidic peatland habitats for aquatic macroinvertebrates is recommended to document populations of northern at the southern periphery of their ranges. These could function as indicators of climate change.
