This butterfly is very similar to the pale clouded yellow, from which it cannot always be separated with certainty. In both sexes, the wings are more rounded and appear less long and swept back - though this can be very subjective. The male is a brighter lemon yellow and the orange spot on the hindwing is also brighter in Berger's.

The species is more sedentary than pale clouded yellow and more restricted to calcarious soils. In Switzerland Berger's is the default species and is much commoner around me.
