The clouded Apollo (Parnassius mnemosyne) is a butterfly species of the family of swallowtail butterflies (Papilionidae) found in the Palearctic ecozone. Clouded Apollos inhabit meadows and woodland clearings with plenty of flowering plants, both in the lowlands and in the mountains. It is not usually found at altitudes above 1500 m except in the Central Asian mountains where it is also known from higher altitudes.
