Some animals and insects(昆虫)use camouflage that is, they change color so that it is the same as the color of the tree or plant on which they are sitting. Others have developed a color thousands of years which is like the color of their living place.
One of the second kind is the Peppered Moth, which is found in England. It is light brown in color, and likes to rest on trees which are also light brown. This makes the moth difficult to be seen. It means that birds are less likely to see it and eat it.
