Batesian mimicry is a case of protective or defensive mimicry, where the mimic does best by avoiding confrontations with the signal receiver. It is a disjunct system, which means that all three parties are from different species. [ 11 ]
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.
Batesian mimicry, named for the 19th century naturalist Henry Walter Bates who first noted the effect in 1861, "provides numerous excellent examples of natural selection" [16] at work. The evolutionary entomologist James Mallet noted that mimicry was "arguably the oldest Darwinian theory not attributable to Darwin."
This is known as Batesian mimicry, after Henry Walter Bates, a British naturalist who studied Amazonian butterflies in the second half of the 19th century. [79] Batesian mimicry is frequency dependent: it is most effective when the ratio of mimic to model is low; otherwise, predators will encounter the mimic too often. [80] [81]
Mimicry is a resemblance of one species to another which protects one or both species. The resemblance can be in visual appearance, behaviour, sound, and scent. There are many types, which can be combined. [5] Defensive or protective mimicry enables organisms to avoid harmful encounters by appearing to their enemies to be something that they ...

Research has argued that the viceroy may be unpalatable to avian predators. If that is the case, then the viceroy butterfly displays Müllerian mimicry, and both viceroy and monarch are co-mimics of each other. [17] Some literature suggests that the queen-viceroy may not be a good model-mimic pair for Batesian mimicry.
