1) The target species on this image is a Heraclides (Papilio) anchisiades, Id:ed by Jorge Bizarro, one of the top people on Nymphalides and Moths and Hawk Moths in tropical America. The yellow ones and white ones I have not Id:ed. I have learned there are several similar species. I ´d appreciate if you like to give them a try.

Thanks for sending your image of a puddling Ruby Spotted Swallowtail. According to Learn About Butterflies: “Heraclides anchisiades is a very common and widespread species, found from Texas to Paraguay.” The yellow and white butterflies are in the family Pieridae, the Whites and Sulphurs, but we cannot provide you with a conclusive species identification based on your image. There are many species pictured on Butterflies of the Amazon & Andes. This puddling behavior is a communal activity that often involves several different families of butterflies congregating to take in moisture as well as dissolved minerals.
