Clouded Sulphur Butterfly
The markings of the Clouded Sulphur Butterfly are similar to those of an Orange Sulphur, however, there is no orange on this butterfly and the yellow colour is very light and almost faded looking. As well, the post median markings on the hind wing do not seem as prominent as those of a Orange Sulphur. At first I thought perhaps this might be a Pink-edged Sulphur as the pink edging and head on this butterfly is very rich, however, the central spot on the hind wing of this butterfly is double whereas the spot on the hind wing of the Pink-edged would be a single one. Also the Pink-edged Sulphur has no hind wing postmedian spots.
