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

open access: yesAdvanced 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.

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

open access: yesEcology 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

open access: yesMolecular 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 ...

Las cargas polínicas en las mariposas (Lepidoptera: Rophalocera) de la parte alta de la cuenca del río Roble-Quindío-Colombia

open access: yesCaldasia, 2001
En 335 cargas de polen provenientes de las proboscides y de los ojos de las mariposas diurnas que frecuentan los pastizales y los interiores de bosque en la parte alta de la cuenca del Río Roble (Quindío-Colombia), se identificaron 31 granos de polen ...

Selective sweeps on novel and introgressed variation shape mimicry loci in a butterfly adaptive radiation.

open access: yesPLoS Biology, 2020
Natural selection leaves distinct signatures in the genome that can reveal the targets and history of adaptive evolution. By analysing high-coverage genome sequence data from 4 major colour pattern loci sampled from nearly 600 individuals in 53 ...

Two Thousand Generations of Hybridisation in a Heliconius Butterfly [PDF]

open access: yesEvolution, 1971
The neotropical butterfly Heliconius melpomnene (L.) is extremely polymorphic in some parts of its range. About fifty varieties have been named from three localities in the west of Guyane (French Guiana), where perhaps many thousands of specimens have been collected for export by dealers (Joicey and Kaye, 1917; 1919).

Predicted chemosensory proteins, odorant binding proteins and olfactory receptors in the H. melpomene reference genome

open access: yes, 2015
The data file contains putative coding and amino acid sequences for the chemosensory protein (CSP), odorant binding protein (OBP) and olfactory receptor (Or) gene families identified in the version 1.1 Heliconius melpomene melpomene reference genome ...

Natural hybridization in heliconiine butterflies: the species boundary as a continuum

open access: yesBMC Evolutionary Biology, 2007
Background To understand speciation and the maintenance of taxa as separate entities, we need information about natural hybridization and gene flow among species.

Sexual behavior, intraspecific signaling and the evolution of mimicry among closely related species

open access: yes, 2009
textMimicry, an adaptation to deceive, fascinated early naturalist and has been proof of evolution by natural selection since proposed by Henry W. Bates 150 years ago.

Sequence alignment fasta files of 634 loci from 5 Heliconius species

open access: yes, 2017
This is a compressed directory of 634 anonymous loci obtained from RNA-Seq data and aligned for phylogenetic analysis. The data come from 5 Heliconius species: Heliconius melpomene, Heliconius erato, Heliconius sara, Heliconius doris, and Heliconius ...
