Mnemosyne - Parnassius mnemosyne L.

As for C. hero, P. mnemosyne was a very local but often abundant species in forest meadows on the island of Sealand (Sjślland). It was last seen in 1961. The reasons for the extinction are mainly  drainage, planting of spruce (Picea abies) in forest meadows and lack of grazing by horses or cattle.
