Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates , who worked on butterflies in the rainforests of Brazil.
Comparison of Batesian and Müllerian mimicry, illustrated with a hoverfly, a wasp and a bee. In Müllerian mimicry, two or more species have similar warning or aposematic signals and both share genuine anti-predation attributes (e.g. being unpalatable), as first described in Heliconius butterflies. [53] This type of mimicry is unique in ...
Locomotor mimicry is a subtype of Batesian mimicry in which animals avoid predation by mimicking the movements of another species phylogenetically separated. [1] This can be in the form of mimicking a less desirable species or by mimicking the predator itself. [1] Animals can show similarity in swimming, walking, or flying of their model animals.
Mimicry is a form of defense which describes when a species resembles another recognized by natural enemies, giving it protection against predators. [2] The resemblance among mimics does not denote common ancestry. Mimicry works if and only if predators are able to learn from eating distasteful species.
There are few well-studied examples of mimicry in vertebrates. [1] Still, many of the basic types of mimicry apply to vertebrates, especially among snakes. Batesian mimicry is rare among vertebrates but found in some reptiles (particularly snakes) and amphibians. [2] [3] Müllerian mimicry is found in some snakes, birds, amphibians, and fish.

Bright and distinctive colour patterns in butterflies which are distasteful to predators help communicate their aposematism (toxicity or inedibility) thus preventing a predator from preying on it. In Batesian mimicry , wing colour patterns help edible Lepidopterans mimic inedible models while in Müllerian mimicry inedible butterflies resemble ...
Mimicry causes often closely related species to have completely different wing patterns, for example the genus Thisbe. [5] Many species mimic the stain and stripe pattern of toxic Nymphalidae. Batesian mimicry seems to be more common than in any other insect family of similar size. [6] Reasons for this are unknown.
