Aeshna canadensis

Walker, 1908

Dragonfly Page|Damselfly Page|Home Page

The Canada Darner has 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.

This is a transcontinental species, but the small isolated population (northwestern and north-central counties of Nebraska plus the Black Hills of South Dakota) is over 300 miles west of the nearest Iowa population and 900 miles southeast of the Montana population. They seem to be rare in all counties except Cherry, where they are fairly common.
