The Danube Clouded Yellow occurs in dry, warm grassland where its foodplant, the broom Chamaecytisus ratisbonensis, C. supnus, C. capitatus, C. austiracus are abundant. However, the amount of shelter from bushes can vary considerably. The female lays her eggs on the foodplant, the caterpillars hibernate in the litter layer. It has two to three broods a year. In contrast to the Eastern Pale Clouded Yellow, this species has disappeared from most of its former locations in Central Europe and is now extinct in several countries.
