Ischnura damula is very similar and we may not be able to separate them in areas where their ranges overlap. But damula does not range into southern British Columbia, Washington, Oregon, California, Nevada, Idaho, Montana, and western Wyoming. So all similar images in those areas can be assumed to be Ischnura cervula.
