It exhibits habitat segregation between sexes and has been documented with biased sex ratios, factors that complicate conservation efforts. The Canadian population is restricted to the Minesing Wetlands in Ontario, while U.S. populations occur in Michigan and other states with suitable calcareous wetland habitats.
