Distribution edit
This species is Holarctic in distribution. It is widely distributed worldwide in northern North American and Europe. It is a common in wetlands, including bogs, fens, and woodland pools.[2] In North America, it occurs throughout much of Canada and primarily in the northern parts of the United States.[2] It may be introduced in North America.[3][5] external map
