This is a local butterfly of southern
Europe with tendencies to migrate northwards. It is very closely similar
to the Berger's Clouded Yellow, C.
alfacariensis. Identification hints are given under that
butterfly. To illustrate how similar these species are, I recount a little
story. In some of the early books on the butterflies of the UK there was
only one known migrating "pale" Clouded Yellow. Illustrations in these
books were usually the relatively far rarer migrant Berger's Clouded
Yellow, C. alfacariensis. The speculation is that because they are
the brighter butterfly they would look better on the illustrations.
