Difference between Batesian and Mullerian Mimicry

Difference between Batesian and Mullerian Mimicry

Mimicry is a form of camouflage that occurs when one species of an animal closely resembles another. There are two main types of mimicry: Batesian and Mullerian. In Batesian mimicry, the mimic is weaker and poses no threat to the predator. Mullerian mimicry occurs when multiple harmless species imitate a dangerous species in order to deter predators. While both forms of mimicry have their benefits, Mullerian mimicry is thought to be more advantageous because it results in greater protection for all of the mimicking animals.

What is Batesian Mimicry?

A Batesian mimicry is a form of camouflage in which one species (the Batesian mimic) benefits by imitating another species (the Batesian model) that is toxic or otherwise dangerous to predators.

  • Batesian mimics are often paler or less brightly colored than their models, making them less conspicuous and less likely to be eaten. In some cases, Batesian mimics may also imitate the call or other behavior of their models.
  • Batesian mimicry is named after British naturalist Henry Bates, who first described the phenomenon in 1862. Batesian mimicry is found throughout the animal kingdom, from insects to fish to mammals.
  • Some well-known examples include the kingbird-of-paradise (which resembles a venomous snake), the monarch butterfly (which tastes unpleasant to predators), and the Jacky dragon (which imitates the appearance and behavior of a much larger and more dangerous species).

Although Batesian mimicry can be beneficial to both species involved, it can also put pressure on already endangered species by increasing their likelihood of being eaten. As such, Batesian mimicry is not always considered an evolutionary success.

What is Mullerian Mimicry?

  • Mullerian mimicry is when two or more poisonous or unpalatable species share similar markings, making it difficult for predators to distinguish between them. This type of mimicry is named after German naturalist Fritz Muller, who first proposed the theory in 1879.
  • Mullerian mimicry is often found in nature, with many examples occurring among butterflies and venomous snakes. One of the most famous Mullerian mimics is the monarch butterfly, which shares its orange and black patterning with a number of other unpalatable species.
  • By looking alike, these species gain a form of protection from predators, who learn to avoid all of the look-alikes after being fooled once or twice. Mullerian mimicry is just one example of the many ways that nature has evolved to help animals survive in a hostile world.

Difference between Batesian and Mullerian Mimicry

Batesian and Mullerian mimicry are two terms used to describe how one species protects itself from predators by looking like another, more poisonous or dangerous species.

  • Batesian mimicry is named after British naturalist Henry Bates, who first described it in 1861. Batesian mimicry occurs when a harmless species (the Batesian mimic) evolves to look like a dangerous or poisonous species (the model).
  • The Batesian mimic benefits from the association with the model by deterring predators that avoid the model because of its toxicity. In contrast, Mullerian mimicry is named after German zoologist Fritz Muller, who described it in 1879.
  • Mullerian mimicry occurs when two or more dangerous or poisonous species evolve to look alike. By looking alike, the Mullerian mimics gain the benefit of deterring predators that have learned to avoid any member of the group.

Batesian and Mullerian mimicry are both examples of how evolution can lead to the development of new and innovative adaptations that help a species survive.


While Batesian mimicry is more common, Mullerian mimicry is thought to be more effective. In the world of online marketing, it’s important to know the difference between these two types of mimicry and how they can work for or against you. When you understand your competition and what strategies they are using, you can create a counterattack that will give you an edge in the marketplace.
