The Canada Darner is a northern species with a deep, right angle cut-out in the first side stripe on the thorax. The thoracic stripes on the male may be blue or green. The claspers are of the simple type. Females usually have green thoracic and abdominal markings but may also have blue markings.

There is a small isolated population in the northwestern counties of Nebraska plus Custer County, SD, which is over 300 miles west of the nearest Iowa population and 900 miles SE southeast of the Montana population. They seem to be rare in all counties exceptCherry, in which they are fairly common.
