Mül·le·ri·an mimicry

 (myo͞o-lîr′ē-ən, mə-, mĭ-)
A form of protective mimicry, especially in insects, in which two or more distasteful or harmful species closely resemble each other and are therefore avoided equally by all their predators.

[After Johann Friedrich Theodor (Fritz) Müller (1821-1897), German-born Brazilian zoologist.]

This phenomenon, known as Mullerian mimicry, is considered evolutionary biology's oldest mathematical model and was put forward less than two decades after Darwin's theory of evolution by natural selection.
"The millipedes that copy Apheloria polychroma use what is called Mullerian mimicry, where different species converge on a shared aposematic (warning signal) to defend themselves against a common predator.
These species apparently form Mullerian mimicry rings, in which toxic species adopt the same warning colour patterns so a predator will more quickly learn which species to avoid.
The differences in feeding deterrence reported in the literature for various metabolites from nudibranchs are in accordance with the concept that Batesian and Mullerian mimicry are two extreme ends of a continuum and that the species within a Mullerian mimetic circle might vary in their deterrent potential (Mallet, 1999; Balogh et al., 2008; and references therein).
