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 ...
It had been long accepted that the viceroy practiced Batesian mimicry, with the monarch and the queen serving as models. Batesian mimicry is a type of defensive behavior in which a palatable species closely resembles unpalatable or toxic species to avoid predation.
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.
The butterfly is large with a 120 to 150 millimetres (4.7 to 5.9 in) span. It has four male and many female forms, the females being highly polymorphic and many of them being mimics of unpalatable butterflies. This species has been studied extensively for understanding the genetic basis for polymorphy and Batesian mimicry. As many as twenty-six ...
Sesiidae are characterized by their hymenopteriform [a] Batesian mimicry, frequently of identifiable species. [2]: 11, 16 Most species of Sesiidae have wings with areas where scales are nearly completely absent, resulting in partial, marked transparency. [2]: 11 Forewings are commonly elongated and narrow in the basal half.
In Batesian mimicry, wing colour patterns help edible lepidopterans mimic inedible models, while in Müllerian mimicry, inedible butterflies resemble each other to reduce the numbers of individuals sampled by inexperienced predators. [8] Scales may have evolved initially for providing insulation.
Papilio dardanus, the Saharan swallowtail, African swallowtail, mocker swallowtail or flying handkerchief, is a species of butterfly in the family Papilionidae (the swallowtails). The species is broadly distributed throughout Sub-Saharan Africa. [2] The British entomologist E. B. Poulton described it as "the most interesting butterfly in the ...
