Clouded sulphur on smartweed. The smartweed is a tall think plant with many small pink flowers. The butterfly is holding onto the left side of the flower, facing right. It is mostly yellow with a few black spots on each wing. There is a large black spot near the top of the hindwing with a white dot in the middle of it. The forewing has a large white spot in the middle, surrounded by pink. The outer edges of the wing are also pink.
