[Odonata-l] My last dragonfly of the year ;-)

[Pilon, Michel]

Hello all,
 
First of all, let me wish you a great new year 2008 filled of Happiness, Love and Health :-)
 
Here is the picture of a flying dragonfly photographied within a marsh in Quebec near the Vermont borders last August...
 
Looking at it I'm hesitating between the Canada darner (Aeshna canadensis) and the Lance-tipped darner (Aeshna constricta)....
 
Do you think we can identify it? Any idea/suggestions?

Thank you very much in advance,
