High Contrast Markings Can Negate the Benefits of Transparent Camouflage
Ecology and Evolution, Volume 16, Issue 4, April 2026.Transparency is perhaps theoretically the most efficient means of achieving camouflage; however, in application, species show considerable variance in their degree of transparency. We demonstrate the fragility of transparent camouflage, detailing how imperfections reduce efficacy with implications in predation risk. ABSTRACT Transparency is, in theory,

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 ...

Inferring Predator Behavior from Attack Rates on Prey-Replicas That Differ in Conspicuousness [PDF]
, 2014 Behavioral ecologists and evolutionary biologists have long studied how predators respond to prey items novel in color and pattern. Because a predatory response is influenced by both the predator’s ability to detect the prey and a post-detection ...

Fearful symmetry in aposematic plants [PDF]
Plant Signaling & Behavior, 2011 Symmetry has been proposed to increase the efficiency of visual aposematic displays in animals, and I suggest that it may also be true for many aposematic spiny or poisonous plants. For instance, in the very spiny plant taxa cacti, Aloe sp., Agave sp.

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Alkaloid defenses of co-mimics in a putative Müllerian mimetic radiation [PDF]
, 2014 Background Polytypism in aposematic species is unlikely according to theory, but commonly seen in nature. Ranitomeya imitator is a poison frog species exhibiting polytypic mimicry of three congeneric model species (R. fantastica, R.

Optical Diversity and Nanostructural Organization in the Colored Scales of Sternotomis
Advanced Optical Materials, Volume 14, Issue 12, 25 March 2026.Vivid colors in Sternotomis beetles originate from nanoscale photonic architectures embedded within individual scales. Here, we provide a comparative optical and structural analysis of 57 scale types that reveal how ordered, quasi‐ordered, and disordered 3D networks tune color, saturation, and angular response.

Pattern Matters in the Aposematic Colouration of Papilio polytes Butterflies
InsectsMany 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.

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.
