Variable Darner

Aeshna interrupta

Variable Darner, Aeshna interrupta interrupta
This is a typical individual of the nominate subspecies, showing broken thoracic stripes. This subspecies is the most commonly found east of about Thunder Bay. I photographed this individual in Algonquin Provincial Park, Ontario during July, 2006.

Some individuals of the nominate subspecies show a partly connected thoracic stripe. This photo was taken in Algonquin Provincial Park, Ontario during July, 2006.
 
Variable Darner, Aeshna interrupta interrupta
This is a very abnormal individual. I had never seen A. interrupta with such connected thoracic stripes. A search of E.M. Walker's Odonata of Alaska and Canada revealed reference to individuals such as this. I photographed this individual in Algonquin Provincial Park, Ontario during August, 2006.
 
Variable Darner, Aeshna interrupta lineata
This is the typical form of the "Lineate" subspecies (A. i. lineata) showing narrow, straight thoracic stripes. I photographed this individual in southeastern Manitoba, where this subspecies was common. Interestingly, I caught this individual as it was in tandem with a female Canada Darner (A. canadensis). I took this photo in August, 2006.
