This study examines the relationship between diversification and phenotypic evolution in Ithomiini butterflies, finding trait-specific and geographically structured links between forewing shape evolution and diversification.

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 examines elevational gradients in Ithomiini butterfly communities across two Neotropical regions, finding consistent patterns in diversity and phylogenetic structure shaped by habitat filtering and biotic interactions.

The paper quantifies how different antipredator defenses—crypsis, aposematism, and evasiveness—effectively reduce predation in wild butterfly-prey systems.

This study examines spatial patterns of Mullerian mimicry in Neotropical butterflies, revealing convergent climatic niches and vulnerability to climate change.

This study examines two Neotropical butterfly radiations, revealing high rates of hybridization and chromosomal rearrangements as drivers of diversification.

This study reconstructs the phylogeny of Neotropical limenitidine butterflies to explore the evolution of mimicry patterns and their relationship with speciation.

This study identifies shared genetic mechanisms underlying convergent mimicry coloration in Lepidoptera, showing that non-coding regions near ivory and optix genes are consistently associated with color pattern switches across distantly related species.

The paper uses citizen science data to analyze wing pattern similarity in Neotropical butterflies, revealing widespread convergence in mimicry rings across regions.

The paper challenges the holocentricity of butterfly chromosomes by showing acrocentric and sub-metacentric chromosomes through improved cytogenetic techniques.

The paper investigates the developmental and structural basis of wing transparency in the glasswing butterfly Greta oto, identifying reduced scale precursor cell density and wax-based nanopillars as key features.
