The Clouded Apollo occurs in mountainous regions on damp to moderately dry grassland, usually with woodland or scrub in the neighbourhood. The butterflies can often be seen visiting red or purple flowers for the nectar they need. The foodplant is Corydalis, that at the time of egg laying is not yet above ground. The eggs are laid on its dried stems, on grass blades, or on other plants not too far from the foodplants. The egg hibernates. In the spring, as soon as it has released itself from the egg, the small caterpillar starts its search for a suitable foodplant. When fully-grown, it pupates in a closely spun cocoon of fine threads, situated above the ground in the leaves of the foodplant. The Clouded Apollo has one generation a year.
