Welcome back to the new NEFF. Take a break from Twitter and Facebook. You don't go to Dicks for your fly fishing gear, you go to your local fly fishing store. Enjoy!
I was looking at the picture myself trying to figure out the same thing. I studied it for a while and tried to figure out if the eyes were bigger (male) or smaller(female). It was a tough call for me, but now that I look at the tails, I think you might be right. When I'm on the Beaverkill in the morning, I'm going to hopefully capture a few more and take pics of them.
