Orange Sulphur

 The orange sulphur is a common yellow butterfly that can be found through out most of North America. They are very similar in appearance to the clouded sulphur when perched, as in the photo above. However when they open their wings the upper surface is more of an orange color where the clouded sulphur is yellow on the tops of their wings.

It is possible to tell the difference between male and females by looking at the black border on the upper side of the wings. With the male the border is solid black, like in the photos above, while the females have yellow spots in the border. Orange sulphurs larval host plant is alfalfa, clovers, and other legumes.
