Genomic hotspots for adaptation: the population genetics of Müllerian mimicry in the Heliconius melpomene clade.

PLoS Genetics, 2010
Wing patterning in Heliconius butterflies is a longstanding example of both Müllerian mimicry and phenotypic radiation under strong natural selection. The loci controlling such patterns are "hotspots" for adaptive evolution with great allelic diversity ...

Evolutionary dynamics of genome size and content during the adaptive radiation of Heliconiini butterflies

Nature Communications, 2023
Heliconius butterflies, a speciose genus of Müllerian mimics, represent a classic example of an adaptive radiation that includes a range of derived dietary, life history, physiological and neural traits. However, key lineages within the genus, and across

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Disruptive sexual selection against hybrids contributes to speciation betweenHeliconius cydnoandHeliconius melpomene [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001
Understanding the fate of hybrids in wild populations is fundamental to understanding speciation. Here we provide evidence for disruptive sexual selection against hybrids between Heliconius cydno and Heliconius melpomene. The two species are sympatric across most of Central and Andean South America, and coexist despite a low level of hybridization.

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, Volume 13, Issue 19, 2 April 2026.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Female behaviour drives expression and evolution of gustatory receptors in butterflies.

PLoS Genetics, 2013
Secondary plant compounds are strong deterrents of insect oviposition and feeding, but may also be attractants for specialist herbivores. These insect-plant interactions are mediated by insect gustatory receptors (Grs) and olfactory receptors (Ors).

Are Toxic Butterflies More Easily Detected by Human ‘Predators’?

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Aposematic signals are often thought to be conspicuous and stable across environments. Yet, butterflies can have distinct colours on their dorsal and ventral sides which contradict this prediction. We found that despite toxic butterflies having similar detectability on both sides, only dorsal detectability positively correlated with toxicity.

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

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 ...
