One of the most common families of butterflies that can be seen through out the summer are the sulphurs. Sulphurs are recognizable because of their yellow, sulphur, color. We have five different types of sulphurs in the area in which I live, they include the clouded sulphur, orange sulphur, pink-edged sulphur, dainty sulphur, and the little yellow.
The most common sulphur around here is the clouded or common sulphur. It can be distinguished from the orange sulphur because it lacks orange on the fore wing, although cross breading between clouded and orange sulphurs does sometimes occur. It can be distinguished from the pink-edged because it has two spots, one large and one small on the hind wing. Sulphurs are often found sucking moisture out of sand, puddles or animal dung. When groups are found drinking, as in the photo above, it is called puddling.
