The Berger’s Clouded Yellow is a butterfly of dry, open grasslands on calcareous soils. In the northern part of its distribution range, it often occurs on the south-facing slopes of hills or mountains. Eggs are mostly laid on Horseshoe Vetch (Hippocrepis comosa), also on Crown Vetch (Coronilla varia). Hibernation takes place on the foodplant, or on the ground in the litter layer. For pupation the caterpillar attaches itself to a foodplant, turning into a pupa, suspended by a silken girdle. This species has two or three broods a year. The adult Berger’s Clouded Yellow and Pale Clouded Yellow are so similar that it is not possible to identify them with certainty, while this is easy for the caterpillars.
