The moth was white with small black speckles but over time it evolved to being almost black in parts of the UK because of heavy industrial pollution. The change made it less obvious to predators against backgrounds of grime and soot.
Having declined by more than two thirds compared to 40 years ago, it is regarded as a classic example of natural selection and has consequently become known as “Darwin’s moth.”
