WebMelanism has appeared in the European and North American peppered moth populations. Information about the initial rise in melanic frequency is scarce. Much more is known about the subsequent fall in phenotype frequency, because it was measured with moth traps. A black peppered moth was found in 1811, a rareity, no doubt caused by a gene mutation.
