In Batesian mimicry, the mimic effectively copies the coloration of an aposematic animal, known as the model, to deceive predators into behaving as if it were distasteful. [ a ] The success of this dishonest display depends on the level of toxicity of the model and the abundance of the model in the geographical area.
In Batesian mimicry, the mimic resembles the model, but does not have the attribute that makes it unprofitable to predators (e.g., unpalatability, or the ability to sting). In other words, a Batesian mimic is a sheep in wolf's clothing. Mimics are less likely to be found out (for example by predators) when in low proportion to their model.
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 ...
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.
Batesian mimicry occurs in multiple vertebrates, but is less prevalent in mammals due to a relative rarity of well-marked harmful models. However, this form of mimicry is prevalent in snakes and frogs, where chemical defense has coevolved with distinct coloration. Still, mammals have evolved Batesian mimicry systems where particularly powerful ...
The distinction between aggressive mimicry and predator camouflage depends on the signal given to the prey, not easily determined. Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host.
Poulton's 1890 book, The Colours of Animals, written during Darwinism's lowest ebb, used all the forms of coloration to argue the case for natural selection. Cott described many kinds of camouflage, and in particular his drawings of coincident disruptive coloration in frogs convinced other biologists that these deceptive markings were products ...
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.
