For the purpose of Batesian mimicry, ants are also good model organisms because they are unpalatable for many other animals due to characteristics, or combinations thereof, such as formic acid, stings, strong mandibles that bite, and in general an aggressive nature [21, 22, 28].
This extraordinary Batesian mimicry polymorphism has been hypothesized by Del Claro (1991) as resulting from density-dependent selection.
Batesian mimicry: In the present study the similarity between juveniles of Plotosus lineatus, Plotosus japonicus and Pholidichthys leucotaenia is emphasized.
fontandraui is chemically defended in much the same way as its aposematic co-occurring and blue-colored congeners of a proposed Mullerian mimetic circle and that it does not rely on Batesian mimicry. In view of the monophyletic origin of this group of sympatric Hypselodoris nudibranchs, the similar color pattern and their aposematism may have been inherited from their common ancestor and therefore not the result of convergent evolution.
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. Monarch caterpillars spend their leisure time eating milkweed leaves containing a toxic chemical that eventually makes their adult self taste bad.
Bates observed that some edible insects survive predation by imitating the gaudy colouring of poisonous species--a strategy now known as Batesian mimicry. In the preface to his memoirs, The Naturalist on the River Amazons, Bates wrote that he had collected 14,712 zoological species (not specimens, which were many times that number) and 'no less than 8,000 of the species here enumerated were new to science [Bates's italics]'.
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).
