Each peppered moth in the samples was identified by phenotype as melanic (solid black), typical (patterned wings), or intermediate (insularia). The range of phenotypic differences results from multiple alleles at a single locus, with the allele producing full melanism as dominant (Lees and Creed 1977; West 1977).
Biston betularia f. typica, the light-coloured peppered moth. The evolution of the peppered moth has been studied in detail over the last 150 years. At first, almost all of the moths were light coloured. This gave them camouflage against the light-coloured trees and lichens where they rested during the day. As pollution increased during the Industrial Revolution in England, many of the lichens died out. The trees became blackened by soot, and most of the light-coloured moths, or typica, became rare. At the same time, the dark-coloured, or melanic, moths, c
