Hine’s Emerald is a medium-sized dragonfly (about 60 millimetres long) with bright green eyes, a metallic green thorax with two lateral yellow stripes, and a blackish-brown abdomen.


In Ontario, Hine’s Emerald has been documented at just one site in Minesing wetland in Simcoe County (west of Barrie). It is also found in Wisconsin, Michigan, Illinois and Missouri.


Hine’s Emerald lives in groundwater-fed wetlands with grassy vegetation. Larvae use crayfish burrows during periods of low water and during the winter.


This dragonfly is threatened by changes to water level fluctuations and quality in wetlands. The European Common Reed, an invasive species which forms dense stands in fens, virtually eliminating native biodiversity, threatens the only Ontario site for this species.


Hine’s Emerald and its habitat are protected under Ontario’s Endangered Species Act.
