This study examines how sympatry influences the evolution of iridescence in Morpho butterflies, finding evidence of convergence due to evasive mimicry and sexual dimorphism in selective pressures.

This study examines how avian predators in Ecuador respond to different prey types, finding that specialist birds avoid evasive, iridescent prey more than generalists.

This study shows wild Morpho butterflies trade speed for erraticity in escape flight, increasing unpredictability but reducing flight speed.

The paper shows that male-male competition can drive the evolution of divergent daily reproductive timing, leading to sympatric speciation through genetic incompatibilities.

The paper examines opsin gene evolution in Morpho butterflies, finding positive selection and co-evolving amino acids linked to light environment and wing coloration.

This study examines how mutualistic Mullerian mimicry influences macroevolutionary diversification patterns in Ithomiini butterflies, finding that color pattern age drives species richness but not phylogenetic diversity.

This study compares visual and chemical traits in sympatric and allopatric Morpho butterfly species to assess how ecological interactions drive trait evolution.

This study examines the Z-chromosome evolution in Morpho butterflies, finding increased genomic rearrangements and positive selection, suggesting a role in speciation through pre- and post-zygotic isolation.

This study examines the genome evolution and transmission patterns of Spiroplasma endosymbionts in Morpho butterflies, revealing genome size inflation, horizontal gene transfer, and contrasting transmission dynamics between sympatric species.

The paper assembles and annotates the genomes of three sympatric Morpho butterfly species to study chromosomal rearrangements and pre-zygotic isolation mechanisms.
