        Peppered Moth 

Smoke kills lichen. That is what happened in large areas of Britain during the 19th century due to rapid industrialisation. The light coloured lichens disappeared as the tree trunks were blackened by soot. Pale coloured moths which had been well camouflaged when they rested on tree trunks became very conspicuous and were eaten by birds. Rare dark moths, which had been conspicuous before, were now well camouflaged in the black background. As birds switched from eating mainly dark moths to mainly pale moths, the most common moth colour changed from pale to dark. The moths had evolved. The Peppered moth is one of the best examples of evolution by natural selection and is often referred to as ‘Darwin’s Moth’.

Having adapted so well to survive the earlier damages of industrialisation, this species is now declining overall. Between 1968 and 2002 numbers of the Peppered Moth in Britain fell by almost two thirds, although the causes are as yet unknown.
