Do you know how to see a gray meat fly (sarcophaga carnaria) in this photograph captured in the fields of the town of Altet, in Urgell? This is the new visual challenge that I propose in El Reto de los Lectores de La Vanguardia.
The dynamics of the game is simple. Without cheats. Simply, you have to find the fly that appears in this image, which I reproduce below.
Have you managed to find the fly in the photograph? Yeah? No? Do you think it is a very difficult Visual Challenge? Do you want me to give you a clue to help you solve it?
I don't know if it will help you, although I hope so, but I am going to show you a detailed image of the fly we are looking for.
Has seeing the fly in detail helped you? Have you managed to solve the Visual Challenge? No?... In any case, I am now going to reproduce the photograph again, but this time I have marked the position of the fly with a black circle. It's the solution.
