Emeralds (Family Corduliidae)
The present range of Hine’s Emerald (HEs) is limited to specialized habitats in Michigan, Missouri, Illinois and Wisconsin, but historically the species also flew in Indiana and Ohio. The UWM Field Station sits roughly midway between the northern Illinois and Door County, WI populations. HEs continue to show up near the Bog, sometimes, regrettably, as road kills. They are listed as a Federally Endangered species.
