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.
Such a mimicry complex is referred to as Batesian and is most commonly known by the mimicry by the limenitidine viceroy butterfly of the inedible danaine monarch. Later research has discovered that the viceroy is, in fact more toxic than the monarch and this resemblance should be considered as a case of Müllerian mimicry.
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 ...
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.
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.

Size difference may permit both sexes to exploit different niches. In elaborate cases of mimicry, such as the African butterfly Papilio dardanus, female morphs mimic a range of distasteful models called Batesian mimicry, [27] often in the same region. The fitness of each type of mimic decreases as it becomes more common, so the polymorphism is ...
