<I>Boloria titania</I> Photo (IMAGE) Helmholtz Association Caption The purple bog fritillary (Boloria titania) is now mainly found in the Alps and in the mountains of the Balkans and the Baltics. The cold-loving species is on the common bistort (Polygonum bistortum) as their food plant, and thus reacting very sensitively to changes. A "drifting apart" of the butterfly habitat and food plant by climate change would endanger the species in the future. These cold-loving species may be among the losers of climate change.
