This one is also a mystery to me. I really think that left eye’s weird condition is not a reflection or a refraction, because I’ve been photographing dragonflies for a couple of decades and this is the first time I’ve ever seen anything like this. When I posted it on various social media sites and asked, I didn’t get any particular information beyond “Yeah, that’s weird.” Maybe someday, someone will see this and let me know what the hell is going on.
