There's a good photo of a female at http://www.veluwe...ylota.html which shows the eye separation, and another at http://www.garden...1_6303.jpg which shows how the tip of the abdomen often has a bit of the ovipositor showing. The males are "finished off" in a more rounded shape. Of course, when the females are full of eggs, the abdomen is much more swollen.
