Protective coloration (Crypsis) and mimicry both manifest as a similarity to environmental colors, making the organism difficult to identify. Protective coloration specifically refers to matching the dominant colors of the environment. For instance, lawns are green in spring and summer, while snowy ground is white in winter. In contrast, mimicry involves resembling a specific biological or non-biological entity in the environment; the characteristics of that entity (such as color) do not necessarily dominate the overall environment.
Furthermore, protective coloration is generally independent of the state of motion. For example, the Dead Leaf Butterfly resembles a withered leaf only when it is resting on a branch; once it takes flight, the resemblance vanishes. We may have all experienced this when catching insects: sometimes we see an insect fly from one spot to another, but when we immediately search the new location, we cannot find it right away.
Many animals possess protective coloration, such as the patterns of a leopard or the green of a frog. Many can even change their color. However, the highest level of this phenomenon is mimicry, where not just the color, but the entire physical form is transformed (cases where both color and shape resemble the environment are classified as mimicry). In nature, many organisms rely on protective coloration to evade enemies and preserve themselves in the struggle for survival.
Next, we would like to introduce a cute little insect — the grasshopper! It is very common around us, though it might be harder to spot for those living in the city. Its emerald green appearance blends perfectly with green leaves and trees, such that if we are not careful, it can vanish from our sight in an instant.
