 | | Around the beautiful countryside of Devon, England, lives Biston betularia, the peppered moth. |
 | | Normally this moth is hard to find because it rests on the bark of lichen-covered tree trunks and has wonderful cryptic appearance (it is well camouflaged). |
 | | No longer concealed among the lichen on the tree bark, these moths were eaten at a higher and higher frequency, while the darker moths now survived. |
