Erebia nivalis (Lorkovic & De Lesse, 1954) is an endemic Alpine butterfly, which is restricted to the highest parts of the Eastern Alps and one small region in the Central Alps. To survive in this challenging high mountain environment, the species evolved different strategies, which might be a mixture of oppurtunism and specialised traits. The studied population showed a partial protandrous demography with the minority of males emerging prior to the females, but the majority being synchronized with them, and a comparatively high amount of long‐distance flights, especially for females (see pages 161–171).
