Peppered moth insularia on the bark of a lichen-covered birch. By the time of Kettlewell, it was known in England that there were three varieties of peppered moth. The normal, typica, is whitish-grey in colour with dark speckles on the wings. The colour was a perfect camouflage on light-coloured trees covered with lichens.
Biston betularia f. typica, the white-bodied peppered moth Biston betularia f. carbonaria, the black-bodied peppered moth . The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution.
The peppered moth (Biston betularia) is a temperate species of night-flying moth. [1] It is mostly found in the northern hemisphere in places like Asia, Europe and North America. Peppered moth evolution is an example of population genetics and natural selection. [2] The caterpillars of the peppered moth not only mimic the form but also the ...

Between these two bands is a white space sprinkled with black dots as well as a crescent-shaped black mark near the middle. The overall appearance gives the oak beauty a mottled look. B. strataria ‘s forewings are 17–27 mm (0.67–1.06 in) in diameter, while its wingspan ranges from 40–56 mm (1.6–2.2 in).
Trichodezia albovittata, the white-striped black moth, is a moth in the family Geometridae. It is found from Alaska to Newfoundland and Labrador, south in the east to North Carolina and in the west to northern California. [3] The wingspan is 20–25 mm. Adults are on wing from April to September. The larvae feed on Impatiens species.
Industrial melanism is known from over 70 species of moth that Kettlewell found in England, and many others from Europe and North America. [17] Among these, Apamea crenata (clouded border brindle moth) and Acronicta rumicis (knot grass moth) are always polymorphic, though the melanic forms are more common in cities and (like those of the peppered moth) are declining in frequency as those ...
Haimbachia placidellus, the peppered haimbachia moth, is a moth in the family Crambidae. It was described by Frank Haimbach in 1907. [2] It is found in North America, where it has been recorded from New York and Massachusetts to South Carolina, west to Tennessee. The larvae probably feed on grasses. [3]
