Four Giant Swallowtails (Papilio cresphontes) during a puddling party. During these sessions, the butterflies suck up fluids and take in extra nutritions such as salts and minerals.

Don’t worry, even if the one on the left looks expired, all butterflies all were ok. They were just struggling with a strong breeze at the moment I took this picture. This gives us the opportunity to see both sides of their beautiful wings.
