Transposable element insertions are associated with Batesian mimicry in the pantropical butterfly Hypolimnas misippus

This study identifies transposable element insertions at the M locus in Hypolimnas misippus that drive adaptive atavism for Batesian mimicry of Danaus chrysippus.

Repeated genetic adaptation to high altitude in two tropical butterflies

This study identifies genetic regions under selection in two tropical butterflies adapted to high altitude, showing that standing variation and introgression from high-altitude specialists contribute to parallel adaptation.

Clustering of loci controlling species differences in male chemical bouquets of sympatric Heliconius butterflies

The paper investigates the genetic architecture of male pheromone compound production in Heliconius butterflies, finding significant QTL clustering on specific chromosomes.

Cortex cis-regulatory switches establish scale colour identity and pattern diversity in Heliconius

The paper identifies cis-regulatory regions controlled by cortex that determine scale color identity and pattern diversity in Heliconius butterflies through CRISPR perturbations and chromatin accessibility analysis.

A major locus controls a biologically active pheromone component in Heliconius melpomene

This study identifies a major genetic locus controlling octadecanal production in Heliconius melpomene, a biologically active pheromone component involved in mate choice.

Adaptive introgression across semipermeable species boundaries between local Helicoverpa zea and invasive Helicoverpa armigera moths

The paper examines hybridization and introgression between invasive Helicoverpa armigera and native H. zea moths in Brazil, finding widespread gene flow but limited species boundary loss except for a specific insecticide-resistance region.

Whole-chromosome hitchhiking driven by a male-killing endosymbiont

The paper investigates the origin and spread of a neo-W chromosome in Danaus chrysippus, showing it hitchhiked with a male-killing Spiroplasma endosymbiont due to suppressed recombination.

A novel terpene synthase produces an anti-aphrodisiac pheromone in the butterfly Heliconius melpomene

The paper identifies a novel terpene synthase in Heliconius melpomene that synthesizes (E)-β-ocimene, an anti-aphrodisiac pheromone, showing it evolved independently from plant and other insect TPSs.
