Let’s look at caterpillars as an example of camouflage. The objective of the caterpillars in our scenario is to make it to adulthood so that they can lay eggs. We have three types of caterpillars. One type has spots, another is multi-colored, and the third is a solid color. The only predator of these caterpillars is a species of bird that lives in the region for twelve months of the year. These birds aren’t picky, they’ll eat any caterpillar they can find.

Take butterflies as an example. The objective of the butterflies in our scenario is to survive long enough to lay eggs. We have three types of butterflies.

The only predator of these butterflies is a species of lizard that lives in the region for twelve months of the year. These lizards aren’t picky; they’ll eat any butterfly they can find.
