Notes: The Clouded Sulphur, while common, is greatly outnumbered by the Orange Sulphur. It seems to be more common in the late summer and fall. This species is sexually dimorphic. Dorsally male Clouded Sulphurs have a solid black forewing margin. In females this margin contains yellow spots. In addition there are albinic females who cannot be reliably separated from similar Orange Sulphur females. Males do not reflect unltraviolet as do Orange Sulphur males. Hybrids between Clouded and Orange Sulphurs are common.
