The Pale Clouded Yellow is mostly found on fields of clover or lucerne, but also on meadows that are lightly grazed where many leguminous plants are growing. It prefers open landscapes with few trees or bushes. Eggs are laid singly on many species of Leguminosae. The caterpillar feeds on young leaves and overwinters as half-grown caterpillar. It pupates, suspended in a girdle from a stalk on the foodplant. The Pale Clouded Yellow has two or three generations a year. In the northern part of its range, it is a migrant species, but in most of Central Europe it is a resident. The adult Pale Clouded Yellow is very hard to distinguish from Berger’s Clouded Yellow (Colias alfacariensis), while the larvae are very different.
