The eye, CBS logotype, has it!

Evidently, determining gender on these is tough. I immediately thought "male" because of the not-green abdomen. After doing some research, I'm totally unsure as to how to tell, though I've seen many different rationales, covering both color and body parts. Funniest one was in Dragonflies through Binoculars which explains the differences on the left page, but refuses to assign gender to the photo on the right page. I think that's wise.
