Somatochlora hineana
Hine's Emerald, Hine's Emerald Dragonfly
Somatochlora hineana is a rare dragonfly species endemic to North America, listed as endangered in Canada since 2011 and of conservation concern in the United States. The species is highly specialized, requiring groundwater discharge areas in wetland habitats to complete its life cycle. 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.
