Clouded Yellow;

Clouded Yellows of both sexes normally have deep yellow uppersides with broad black margins, but the females have a row of pale yellow spots within the margins. About 5% of females are of a paler whitish ground colour. These are known as var. helice, and are commonly mistaken for females of the very much rarer Pale Clouded Yellow and Berger's Clouded Yellow. In both of the latter species however the upperside is a beautiful primrose yellow, and the hindwing borders are much narrower.
