Eastern Pondhawk (female)

Nice! I didn't know about the white claspers. Thanks Livan!

I believe this is actually a young male. Males start off green like females and become blue with maturity. The best way to tell the gender in dragonflies is by the shape of the end of the "tail". Yours has the white male claspers. To me it also looks like as if the tail has begun to shift to blue, very similar to this picture: http://bugguide.net/node/view/186010

males are blue
