The Sulphurs and Whites are sometimes common species in the summer season. They are often among the most common butterflies, from the big and fast Cloudless to the low flying Dainty Sulphur. This shot is from an erosion bank of rocky soil in Arizona. The Sulphurs are known for mass puddling and there was obviously something in the wet soil here that was exceptionally fine. Note the flapping Southern Dogface in the upper portion of the group with the yellow poodle-head silhouette. Most of the rest here are also Dogfaces. In the south and in Texas the Dogface can occur in massive numbers. In Arkansas they can be, at most, locally abundant.
