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.
His observations of the coloration of butterflies led him to discover Batesian mimicry. The book contains an evenly distributed mixture of natural history, travel, and observation of human societies, including the towns with their Catholic processions. Only the most remarkable discoveries of animals and plants are described, and theories such ...
Genetic polymorphism and natural selection give rise to otherwise edible species (the mimic) gaining a survival advantage by resembling inedible species (the model). 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 ...
In the simplest case, as in Batesian mimicry, a mimic resembles a model, so as to deceive a dupe, all three being of different species. A Batesian mimic, such as a hoverfly, is harmless, while its model, such as a wasp, is harmful, and is avoided by the dupe, such as an insect-eating bird. Birds hunt by sight, so the mimicry in that case is ...
This is the mimicry by a palatable species of an unpalatable or noxious species. A common example seen in temperate gardens is the hover-fly, many of which – though bearing no sting – mimic the warning colouration of hymenoptera (wasps and bees). Such mimicry does not need to be perfect to improve the survival of the palatable species. [13]
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.
A familiar example is the resemblance of harmless hoverflies (which have no sting) to bees. Müllerian mimicry, where two or more distasteful or dangerous animal species resemble each other. This is most common among insects such as wasps and bees (hymenoptera). Batesian mimicry was first described by the pioneering naturalist Henry W. Bates ...
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.
