A number of species of moths live in the Alps, some of which are believed to have evolved in the same habitat up to 120 million years ago, long before the Alps were created. Blue moths can commonly be seen drinking from the snow melt; some species of blue moths fly as high as 1,800 m (5,906 ft). The butterflies tend to be large, such as those from the swallowtail Parnassius family, with a habitat that ranges to 1,800 m (5,906 ft). Twelve species of beetles have habitats up to the snow line; the most beautiful and formerly collected for its colours but now protected is the Rosalia alpina. Spiders, such as the large wolf spider, live above the snow line and can be seen as high as 400 m (1,312 ft). Scorpions can be found in the Italian Alps.
