Hi James,
Well, as I expect you know, species of some groups of odes are so similar that they cannot be positively identified in the field or from photos. This is true of the spreadwings, bluets and the meadowhawks to name a few groups. They must be captured and the male terminal appendages examined with a hand lens (or microscope) and compared to a chart as those found on page 32 (for the bluets) and page 20 (for the spreadwings) in the Massachusetts Dragonflies/Damselflies field guide. Interestingly, although some 19 species of bluets are covered in the guide, of which 11 occur in Nova Scotia, river bluet is not one of the 19. Could you give the scientific name and possibly the basis for your tentative ID?
Despite all of the above, I would be pleased to take a look at your photos. Thanks for your report.

Hi all:
I also have a recent bluet photo, which I think is a river bluet. I would like opinions. Let me know if you would like to take a crack at the id.
Sincerely,
James R. Hirtle
