The American emerald is a member of the emerald family of dragonflies. Most emeralds can be identified by their metallic green eyes, which is where the Corduliidae family gets its common name. The American emerald is a common emerald or Cordulia. They are usually found in the north eastern part of Minnesota where they like wooded lakes and pond. It can easily be identified here in Minnesota because it is the only emerald with a white ring around the base of the abdomen. I photographed this American emerald at the Tamarac National Wildlife Refuge.
