Anatomy and Appearance

Peppered moths are white with black sprinkles. But some are completely black. The ones that are best at hiding from their predators survive. This is called natural selection. Many animals use camouflage as one of their defense mechanisms, or even their only defense.

Senses and Abilities
Peppered Moth Can Change Their Colors
Over 200 years ago, industrialization in England caused whole landscapes to be covered in soot, which meant that the trees were darker. The white peppered moths were suddenly more visible on the darker trees and were discovered by predators more easily.
Thankfully, there were some darker moths. They were hard to spot on the darker trees and were able to reproduce rapidly. From then on, there were lots of dark and fewer light peppered moths. So, the predators didn’t run out of food. If there were only light moths, only a few of these animals would have survived and this would have had an effect on other animals.
Diversity is important for the survival of a species. In the meantime, the trees in England are light again. There’s hardly any factory soot to dirty the land. And guess what: there are now more light peppered moths than dark.
