Another moth adaptation is mimicry, which confuses or frightens off predators. Moths that can blend into their surroundings during rest have a distinct advantage for survival from predation, as exhibited by the peppered moth. Now the melanic variation had a distinct advantage over the paler moths, as they were better camouflaged on the birch trees. Industrial melanism is a classic example of adaptation, and a classic case took place in the British Isles involving the moth species Biston betularia.
