Pattern Matters in the Aposematic Colouration of Papilio polytes Butterflies

Insects
Many toxic animals display bright colour patterns to warn predators about their toxicity. This sometimes leads other sympatric palatable organisms to evolve mimetic colour patterns to also evade predation.

Mimicry can drive convergence in structural and light transmission features of transparent wings in Lepidoptera

eLife, 2021
Müllerian mimicry is a positive interspecific interaction, whereby co-occurring defended prey species share a common aposematic signal. In Lepidoptera, aposematic species typically harbour conspicuous opaque wing colour patterns with convergent optical ...

Independent Major‐Effect Loci and Limited Trait Associations Characterize Warning Colour Variation Across Sexes and Life Stages in the Wood Tiger Moth (Arctia plantaginis)

Molecular Ecology, Volume 35, Issue 20, October 2026.
ABSTRACT Variation in warning colouration is common, despite strong positive frequency‐dependent selection favouring the most common morph and may arise from spatially or temporally variable selection or associations with other traits. We investigated the maintenance of warning colour variation in the wood tiger moth, Arctia plantaginis, which shows ...

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1672-1685, September 2026.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Ontogenetic shift from aposematism and gregariousness to crypsis in a Romaleid grasshopper - dataset

, 2020
Traits of chemically-defended animals can change as an individual grows and matures, and both theoretical and empirical evidence favour a direction of change from crypsis to aposematism.

Phylogeography and the evolution of correlated traits under multiple origins of aposematism in the poison frog family [PDF]

, 2009
Living organisms are under selection not only for one, but also for several inheritable characters at the same time. Well-sampled and well-supported phylogenies are necessary for the studies of character evolution and their history.

Brightly coloured tissues in limid bivalves chemically deter predators [PDF]

Royal Society Open Science, 2019
Members of the marine bivalve family Limidae are known for their bright appearance. In this study, their colourful tissues were examined as a defence mechanism towards predators.

Antipredatory Strategies of Anurans: An Updated Conceptual Review

Ethology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

Data from: Coarse dark patterning functionally constrains adaptive shifts from aposematism to crypsis in strawberry poison frogs

, 2014
Ecological specialization often requires tight co-evolution of several traits, which may constrain future evolutionary pathways and make species more prone to extinction.

The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

eLife, 2017
Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals. Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not ...
