[Odonata-l] Could it be a Variable Darner??? (No response up to now...)

[Dubois, Robert - DNR]

Hi Michel,
Part of the lack of response may be that male Aeshnas are easy to identify if you can see the right parts (side stripes, face, terminal apps), but none of these are clear in any of the photographs. I agree with Jim that it is not interrupta or constricta. Based on the smidgen of side stripe partially visible in one of the photos it might be canadensis.

Have a great spring!
Bob

Michel,



>From what I can see of the thoracic markings in the second image it is not A. interrupta, and the appendages are wrong for A. constrcta. That leaves A. canadensis, although you may have to consider A. verticalis as well (not sure if the species is in that area or not).

Hello all,

Hum... It looks harder than I thought for I received no answer (0) from anybody concerning that ID...!

I'm hesitating between 3 Darners:

- Aeshna canadensis;
- Aeshna interrupta;
- Aeshna constricta;

As I said, that specimen was photographied in New Hampshire September 12th, 2008.

Maybe the date can help??? Which one can I remove from the above list?

Any suggestion about its ID will be very appreciated :-)


Thank you very much !

Hello all,

Here are 3 pictures of a Dragonfly photographied at the "Old Main in the Mountain" (White Mountain, New Hampshire), September 12th, 2008.

Could it be a Variable Darner (Aeshna interrupta)??
