Clouded Yellow (Colias croceus) is a small butterfly of the Pieridae family. The upper side is golden to orange yellow with a broad black margin on all four wings and a black spot near the centre forewing. The underside lacks the black borders and is lighter, with a more greenish tint, particularly on the forewings. Females differ from the males in having yellow spots along the black borders on the upper side. Like all Colias species they never open their wings at rest.
