[Odonata-l] Are they from the species???

[Pilon, Michel]

Hello, 

I photographied these 3 green dragonflies when I went to the Great Meadows National Park (near Concord) Massachussets (August 31st 2006) for a business trip...

Are they from the same species??? Is it possible to identify them (family/genum/species)??? 

Thank you very much for your precious help :-)
