J, my irreplaceable and invaluable spotter of good things, directed me to these two Clouded Sulphur butterflies in the garden who were making merry, or even hay while the sun shines, on the New England Asters. Clearly they were intent on trying to make more butterflies.

The rear butterfly is the male and can be distinguished from the female which is the one on the flower with more folded wings. The difference being that the females have distinct spots on their dark wing margins.
