Data from: Diversity in Müllerian mimicry: the optimal predator sampling strategy explains both local and regional polymorphism in prey

The convergent evolution of warning signals in unpalatable species, known
as Müllerian mimicry, has been observed in a wide variety of taxonomic
groups. This form of mimicry is generally thought to have arisen as a
consequence of local frequency-dependent selection imposed by sampling
predators. However, despite clear evidence for local selection against
rare warning signals, there appears an almost embarrassing amount of
polymorphism in natural warning colors, both within and among populations.
Because the model of predator cognition widely invoked to explain
Müllerian mimicry (Müller’s “fixed nk” model) is highly simplified and has
not been empirically supported; here, we explore the dynamical
consequences of the optimal strategy for sampling unfamiliar prey. This
strategy, 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. In contrast to Müller’s “fixed
nk” sampling rule, the optimal sampling strategy is capable of generating
a variety of dynamical outcomes, including mimicry but also regional and
local polymorphism. Moreover, the heterogeneity of predator behavior
across space and time that a more nuanced foraging strategy allows, can
even further facilitate the emergence of both local and regional
polymorphism in prey warning color.
