Adaptive Colouration: Mimicry Examples

What is Mimicry?

Mimicry is an adaptation where one species evolves to resemble another species. This resemblance can help the mimic avoid predators, attract prey, or gain other advantages.

There are different types of mimicry, including:

• Batesian Mimicry: A harmless species mimics a harmful one to avoid predators.
• Müllerian Mimicry: Two or more harmful species evolve to look similar, reinforcing the avoidance behavior in predators.
• Aggressive Mimicry: A predator or parasite mimics a harmless or beneficial species to approach its prey or host.

Examples of Mimicry

• Batesian Mimicry: The hoverfly resembles a wasp. Hoverflies are harmless, but their resemblance to stinging wasps helps them avoid predators.
• Müllerian Mimicry: The monarch butterfly and the viceroy butterfly both have similar orange and black patterns. Both are unpalatable to birds, reinforcing the avoidance behavior.
• Aggressive Mimicry: The anglerfish uses a lure that resembles a small fish or worm to attract prey close enough to be captured.

Why is Mimicry Important?

• Survival: Mimicry can increase an organism's chances of survival by reducing the risk of predation.
• Reproduction: Some species use mimicry to attract mates or ensure the survival of their offspring.
• Ecological Balance: Mimicry contributes to the balance of ecosystems by influencing predator-prey relationships.
