Müllerian mimicry, in which both partners are unpalatable to predators, is often used as an example of a coevolved mutualism. However, it is theoretically possible that some Müllerian mimics are parasitic if a weakly defended mimic benefits at the expense of a more highly defended model, a phenomenon known as ‘quasi-Batesian mimicry’. The theory expounded by Müller and extended here for unequal unpalatability, on the other hand, suggests that quasi-Batesian mimicry should be rare in comparison… 
THE EFFECT OF ALTERNATIVE PREY ON THE DYNAMICS OF IMPERFECT BATESIAN AND MÜLLERIAN MIMICRIES
TLDR
This experiment suggests that the availability of alternative prey affects the dynamics of both Müllerian and Batesian mimicry, but in different ways.
Mimicry between unequally defended prey can be parasitic: evidence for quasi-Batesian mimicry.
TLDR
It is shown that mimicry between unequally defended co-mimics is not mutualistic, and can be parasitic and quasi-Batesian, and that many prey species that are currently assumed to be in a simple mutualistic mimetic relationship with their co-Mimic species may be engaged in an antagonistic co-evolutionary process.
Alternative prey can change model-mimic dynamics between parasitism and mutualism
TLDR
The conditions for parasitic or mutualistic relationships between aposematic prey, and a model to examine the hypothesis that the availability of alternative prey is crucial to Mullerian and quasi-Batesian mimicry.
A tale of 2 signals: signal mimicry between aposematic species enhances predator avoidance learning
TLDR
It is demonstrated clearly and unambiguously that mimicry between 2 defended forms can provide substantial protection from uneducated predators in the manner proposed originally by Muller, and the benefits of shared warning signals may be even stronger than Muller originally proposed.
Co-mimics have a mutualistic relationship despite unequal defences
TLDR
It is shown that the relationship between unequally defended species is mutualistic, and selection for accurate signal mimicry is found.
CONSERVATIVE COEVOLUTION OF MÜLLERIAN MIMICRY IN A GROUP OF RIFT LAKE CATFISH

TLDR
Ancestral state reconstructions and statistical comparisons of color pattern divergence in Tanganyikan Synodontis indicate that Müllerian mimicry in these catfish has developed through diversification of an aposematic common ancestor with subsequent conservative mutualistic coevolution among its daughter lineages, rather than advergent evolution of a mimic toward a nonrelated model.
Optimal-Foraging Predator Favors Commensalistic Batesian Mimicry
TLDR
A psychology-based Monte Carlo model simulation of mimicry that incorporates a “Pavlovian” predator that practices an optimal foraging strategy and examines how various ecological and psychological factors affect the relationships between a Model prey species and its Mimic suggests that to understand mimicry in nature it is important to consider the likely presence of alternative prey and the possibility that predation pressure is not constant.
Diversity in Müllerian mimicry: The optimal predator sampling strategy explains both local and regional polymorphism in prey
TLDR
The dynamical consequences of the optimal strategy for sampling unfamiliar prey, based on a classical exploration–exploitation trade‐off, not only allows for a variable number of prey sampled, but also accounts for predator neophobia under some conditions.
Mimicry among Unequally Defended Prey Should Be Mutualistic When Predators Sample Optimally
TLDR
If predators forage efficiently to maximize their long-term payoff, genuine quasi-Batesian mimicry should be rare, which may explain the scarcity of evidence for it in nature.
The evolution of imperfect mimicry in hoverflies
TLDR
Hoverfly mimics fall into three major groups according to their models, involving bumblebees, honeybees and social wasps, with polymorphic and accurate forms being a key feature of mimics of the least noxious models, while highlyNoxious models have poor-quality mimicry.

The viceroy butterfly is not a batesian mimic
TLDR
This classic case of mimicry involving viceroy butterflies, Limenitis archippus (Cramer) (Nymphalidae), and two species they purportedly mimic is reassessed and it is revealed that viceroys are as unpalatable as monarchs, and significantly more unpalable than queens from representative Florida populations.
Testing Müllerian mimicry: an experiment with wild birds
TLDR
It is shown that a moderately defended prey can dilute the protection of a better defended mimic in a quasi–Batesian fashion, but can add protection to a mimic which has the same moderate levels of defence, which match predictions of unconventional theories of mimicry.
Genetics and the Evolution of Muellerian Mimicry in Heliconius Butterflies
TLDR
By hybridizing races of Heliconius melpomene and races of H. erato, it is shown that, as expected from the two-step theory, the races differ at a number of genetic loci, usually unlinked or loosely linked, including at least one mutant of major effect in each case.

TLDR
It is suggested that the most credible of the 29 predator behaviour systems are those which generate results which incorporate Batesian, quasi-Batesian and Muellerian mimicries across the ‘palatability spectrum’.
