Clouded Sulphur (Colias philodice)

Found more commonly in the NC mountains and piedmont, Clouded Sulphurs are fairly rare in the coastal plain. Care must be taken to properly distinguish these butterflies from the similar and more common Orange Sulphur, especially in the springtime when some Orange Sulphurs show very little orange on the dorsal surface. Clouded Sulphurs do not show any orange coloration in the dorsal forewing, although a hint of orange may be present in the ventral forewing of some populations (see Colias eriphyle below).

I took several in-flight photos to try to document the lack of orange on the dorsal wing surfaes. These dorsal shots are blurry and highly cropped but they do suffice!

Many authorities now recognize Eriphyle Sulphur (below) as a separate species from Clouded Sulphur (above).

Note that looking at the ventral might give you the impression of Orange Sulpbur, but the dorsal clearly shows no orange in the forewing.

Note that this very well could be an Orange Sulphur (C. eurytheme), but I do not recall seeing any orange on the dorsal surface in flight, and C. p. eriphyle can show ventral orange on the forewing.

Nice side by side comparison of male sulphurs. Note that the Orange Sulphur shows stronger orange in the disc of the ventral forewing, and a wider black forewing border.
