The clouded Apollo (Parnassius mnemosyne) is a butterfly species of the family of swallowtail butterflies (Papilionidae) found in the Palearctic realm. It is a large butterfly which inhabits meadows and deciduous woodland clearings with plenty of flowering plants, but cannot survive in denser forest. It is found both in the lowlands and in the mountains but not usually found at altitudes above 1,500 m (4,900 ft) except in the Central Asian mountains where it is also known from higher altitudes.
Its range of distribution extends from the Pyrenees, across the Central Massif, the Alps, and the Carpathians as far as central Asia. It inhabits all European countries including Norway, where it appears rarely and only in certain places. A subspecies lived in Denmark, but is now extinct. A great number of geographical races and individual forms are distinguished in this extensive region. The most striking specimens include the dark race from the eastern Bavarian Alps (subspecies hartmanni); form melania has the most pronounced dark colouring.

Possible
About 20% of wildlife watchers report a Clouded Apollo sighting in Triglav National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 109th most-seen of the 260 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May and June
In those months about 30% of wildlife watchers report a Clouded Apollo in Triglav National Park on a given day, against under 5% in August to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Clouded Apollo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 parks where we can rate Clouded Apollo sightings, Triglav National Park ranks 5th at about 20%, level with the leaders once rounded. The best odds are in Gauja National Park (Latvia, about 20%), Vanoise National Park (France, about 20%) and Mercantour National Park (France, about 20%).
GBIF citizen-science records
It is estimated from how often the Clouded Apollo is recorded against all the insects logged in Triglav National Park (17 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
