Stalk-eyed Fly

Thanks, Mark. I just read up a little on these flies - their contests do indeed involve comparing eye stalk size and females tend to go for those with longer stalks. Nature continues to amaze. Thanks again for the spotting, Albert!

Hey Maria I think I remember the male flies measure their eye separation against other males when competing for females... ? amazing end result anyway.

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

Great spotting. I wonder what the advantage is of those eyes sticking way out there in comparison to their perhaps increased vulnerability?
