Blue Dasher - Pachydiplax longipennis - female

Blue Dasher - Pachydiplax longipennis - Female
The Woodlands, Montgomery County, Texas, USA
June 10, 2006
This one's wings are showing its age. Is it a blue dasher? Can you tell the gender?

Yes, Pachydiplax female
It has the coloration of a female or a young male. It has the heavy body of a female. An old male would be blue and would have longer appendages at the rear to hold onto the female during mating. The only thing confusing us are what appear to be green eyes??

 
A very similar specimen confused me today, July 20
I am from Southern Michigan and live about two blocks from a lake and a very large and beautiful bog. The specimen had the same grey-blue-green eye color and thick body as the specimen in this photograph with dull green-yellow thorax and 'hollow' black striping. It had the classic blue dasher hunting strategy making short dashes from and returning to the same perch, landing in a forward leaning position with its abdomen raised. In certain light the abdomen had a dull blue cast but also double striping on the top. No pruinosity was apparent. I also concluded it was Pachydiplax longipennis. I figured it was probably a young male because of the eye color but I am not familiar enough with the species to know if it is the right time of year to see emerging males. Otherwise I guess it could just be a variation of the female coloring? Maybe a subspecies?
