Marsh Bluet,m - Enallagma ebrium - male

Marsh Bluet,m - Enallagma ebrium - Male
Kennebunk, Maine, USA
June 22, 2003
Enallagra ebrium,male

E. ebrium
E. aspersum would have much more black on the body. We will put this one in the guide under Marsh Bluet. Segment 7 is essentially all black and segment 6 half black with long black tip up the center. See Ed Lam, (1) page 74

A bluet perhaps
But I'm certain it's not Coenagrion puella. Nearctica doesn't list that species for North America, and indeed a web search seems to indicate that's a European species. Ditto for the other one:

 
Azure damselfly
V J Hickey: tracked it down: C puella is a European name: UK & West Europe. In Odonata of Mass.,images by Blair Nikula & J Trimble, show M&F as Enallagra aspersum, fam Coenagrionidae...Azure Damselfly. (I had no idea how many Odonata sites there are in the UK.)
