Can you see in these photographs that I have taken along the paths of La Figuerosa, in Urgell, a butterfly? This is the new visual challenge that I propose to you today in The Readers' Challenge of La Vanguardia.
The dynamics of the game are easy. I am going to show you three photographs, arranged in order of difficulty, and in each of them you have to find the butterfly that appears there. And, I can assure you, it is there.
Have you managed to find the butterfly? Yeah? And in the three photographs?... No?... Well, I'm going to give you a clue. To begin with, I will tell you that it is a specimen of Berger's colias (Colias alfacariensis), known in Catalan as "safranera pàl·lida".
Its appearance is as follows. Forewings lemon yellow on the front, with pink fimbriae, with a black dot and bands of the same color. Reverse slightly orange with silver dots, very visible, at the end of the cell. The hindwings have an orange spot. The female has a greenish-white tone, with a similar reverse. And so that you can see what this butterfly looks like, I will now show it to you in detail.
After this help you no longer have an excuse. Have you managed to overcome the Challenge? I hope so. In any case, I am going to show you the three photographs again, but this time I have marked the position of the butterfly. It's the solution.
