This species is Not Applicable because the Mediterranean region is at the margin of the global distribution area of the species and probably less than 1% of its global population occurs in the region.

A central European species occurring between 0-1,800 m asl. In the Mediterranean region, it is present in very small numbers in parts of France, Slovenia and Croatia. Most of the global distribution area of the species is situated outside the Mediterranean region, including southern Sweden, Finland, the Baltic States, Denmark, southeast Belgium, Pyrenees, Switzerland, Austria and as far as the northern Balkans. It is absent from southern Italy, the west and southwest Balkans, Greece and Mediterranean islands. It is further found through Siberia to Mongolia and northwest China. This species is a migrant in the north of its distribution range.

A local species with a restricted range within the Mediterranean region.

The Pale Clouded Yellow is mostly found on fields of clover or lucerne, but also on meadows that are grazed at low intensity 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 a 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, depending on geographical location and altitude of the flight area. 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), yet the caterpillars are very different. The latter species is only found on calcareous grasslands with Horseshoe Vetch (Hippocrepis comosa). Although the Pale Clouded Yellow has a preference for clover and lucerne fields, when migrating, it can turn up almost anywhere.

This species is not believed to face major threats in this part of its distribution.

This species occurs in a number of protected areas across its range. No specific conservation actions are needed.
