The Danube Clouded Yellow occurs in dry, warm grassland where its foodplant, species of the genus Chamaecytisus, are always abundant. However, the amount of shelter from bushes can vary considerably. While the female lays its eggs on the foodplant, the caterpillars hibernate in the litter layer. It has two to three generations a year. The species shows serious declines, especially at the western edge of its range. Within the last years it disappeared most probably from Germany, the Czech Republic, Austria, Hungary, Slovenia and Serbia. Habitats: dry calcareous grasslands and steppes (30%), mesophile grasslands (21%), dry siliceous grasslands (21%), coniferous woodland (8%), mixed woodland (8%).
