Somatochlora septentrionalis, the muskeg emerald, is a species of dragonfly in the family Corduliidae. It is endemic to Canada, where it is found from Yukon and British Columbia east to Nova Scotia and Newfoundland. [2]
Adult muskeg emeralds are 39–48 mm (1.5–1.9 in) long. [4] The body is metallic green, brown and black, with a faint yellow spot on the thorax. This species is identical to Whitehouse's emerald (Somatochlora whitehousei) except in the shape of the male cerci and the female subgenital plate. [4]
Muskeg emeralds occur in open fens with pools of open water. Males patrol over the pools, and females lay eggs by tapping in the open water and in floating vegetation. [4] Adults fly from June to August. [4]
