Bates·i·an mimicry

 (bāt′sē-ən)

A form of protective mimicry, especially in insects, in which a species that is palatable or harmless closely resembles an unpalatable or harmful species and therefore is avoided by predators.

[After Henry Walter Bates (1825-1892), British naturalist.]

These nest observations are only the second published for the cinereous mourner, and they fit with the proposal that mourners exhibit Batesian mimicry.
We are concerned here with a clear case of Batesian mimicry (Bates 1862, 1863) in which a mimic ressembles another species which is unpalatable for different reasons.
This pattern is typical in cases of Batesian mimicry, in which the mimic is relatively scarce, palatable and unprotected while the model is abundant and wellprotected.
This defensive mechanism in which groups of similarly colored species share the cost of the education of predators is called Mullerian mimicry (Muller, 1879) and it implies aposematism, whereas Batesian mimicry occurs in otherwise undefended species that rely on resembling the unpalatable ones (Bates, 1862).
Chapter 3 traps Henry Walter Bates in the Amazon for 11 years of hardship where he collected 14,712 animal species (8,000 of whom were new to science) and 550 different species of butterflies, which led to the discovery of Batesian mimicry.
Batesian mimicry and complex innate behaviors exhibited by promethea moths suggest that predators are a major source of selection (Evans, 1978).
Until relatively recently, Viceroys were the textbook example of Batesian mimicry.
The selection pressure exerted by predators is strong and, as a consequence, traits associated with Batesian mimicry are expected to evolve rapidly (Mappes & Alatalo 1997).
