Hi ya' Wim,
Yup, the males of some mayflies have these "goggly" eyes. These eyes occur mostly in mayfly species that inhabit large, open bodies of water. The enlarged eyes allow the male mayflies to detect females silhouetted against a large expanse of open sky. Mayfly species that inhabit restricted, running waters, generally, do not have these enlarged eyes as there is less sky to be seen from a creek or river. Cool, Wim
Best regards as always, my friend

And to think that so many of us mammal males hide OUR eyes behind sunglasses when we scan for females!
Good shot of a very alien-looking subject!

I have seen these large Mayflies around some of the lakes here in North Carolina but never paid them much attention since I am mainly a small stream fly fisherman. An interesting shot Wim. Next time I am bobber fishing at the lake (don't tell anyone I do such things), I will take more notice.
