Male Seepage Dancer. These damselflies are classified as endangered in Ohio. Seepage Dancers are found in only a few localized populations in Ohio. 

Seepage Dancers can be seen during the summer months at Cedar Bog and Gallagher Fen. The only other place where I have seen this species is near Travertine Fen. Travertine Fen is not accessible without a permit, but you can find interesting things along the bike path near the fen. 

This is a Female Seepage Dancer. Photographed at Cedar Bog.
