Evolution of diversity in warning color and mimicry: polymorphisms, shifting balance, and speciation

Mallet, James; Joron, Mathieu

Peer-reviewednarrative reviewmixed

A review of why warning colours and mimicry rings are diverse when the logic of both predicts convergence on a single pattern, drawing on field experiments with marked butterflies, predator-learning studies and population genetics.

review of warning colour and mimicry systems

Müllerian mimicry is frequency-dependent: a rare pattern is attacked more because predators have not learned it, which drives convergence locally and produces sharply bounded geographic races rather than one global pattern. Batesian mimics are subject to the opposite pressure — becoming common erodes the protection they depend on.

What it means

The authors' reading, and ours. Where they differ, that difference is the point.

How the authors put it

The diversity of warning patterns arises from local frequency-dependent selection acting on a system whose logic would otherwise homogenise it.

How NatureHQ reads it

The frequency dependence is what turns mimicry from a description into a mechanism with predictions. It says why Batesian mimics stay rare relative to their models, why Müllerian rings have hard geographic edges, and why a mimic that becomes too successful undermines itself. It also gives the field its cleanest test: manipulate frequency and predator behaviour should follow.

  • Heavily weighted towards neotropical butterflies, which are the best-studied case by a wide margin.
  • Predator learning is inferred from attack rates on artificial or marked prey rather than observed directly.
  • Geographic race boundaries have several candidate explanations besides mimicry frequency.
