Kel, I like your comment about this fly. I think you have a valid point regarding this fly being the "joke of nature"... ;)

Thank you Sergio and Beaker, your comments are very inspiring!

Thank you Rams and Riekos :)

Leuba and Mark, I guess that is is easy to do a full body exam with eyes like this... And of course the males compares body parts, it's in our nature :P I guess Leuba, that it must be more vulnerable to have this eye setup. But perhaps one eye works just good enough for them. I wonder if the stalk is movable or not.

Sintija, wise comment. I really hope you find them too :)

Tom, thak you for your comment. Too bad I did not understand that it was a jackpot until I uploaded them here. I should have explored them a bit more I think...

Great find and pics Tina! You really hit the jackpot with 7 all in the same place!

Not evolution in general, specific case of natural selection - sexual selection is to blame. Females choose those males who have eyes further away from each other ;) and slowly they move away even more.
Amazing spotting, I want to see them, too! :))

Ha ha! Imagine the view. I wonder if the males compete over eye-width.

They look cute all together in pic 3. Wonder if the eyes are vulnerable at all ?
Great spotting Tiz !

they are a joke of nature, como ornitorrincos e Condylura.

Interesting looking fly. I agree and wonder why these creatures were made this way.

I wonder how much they can move those "stalks"... And why evolution made them eyes this way. I agree Arlanda, impressive little fly! Thank you for your comment!
