Evolution of Reproductive Plasticity in a Seasonal Tropical Environment

Seasonality drives the evolution of reproductive plasticity in butterflies. An extreme form is reproductive diapause, where individuals halt reproduction during unfavourable seasons through cascades translating predictive environmental cues into reproductive phenotypes. How diapause evolves from milder forms of plasticity through changes in those cascades is poorly understood. In the tropics seasonality is common, but it is unclear how phylogenetically widespread reproductive diapause is, and exactly how seasonal tropical climates drive reproductive plasticity. Here, we study reproductive plasticity in Amazon butterflies using a multi-year monthly time series of reproductive phenotypes. Sampling 4 subfamilies across Nymphalids, we observe a phylogenetically widespread occurrence of diapause, suggesting repeated evolutionary changes in reproductive plasticity. Detailed analyses of two Catonephele species reveal a shared temperature response, but dry season diapause only in C. acontius. Thus, evolution of diapause combines cue conservation with species-specific divergence of trait plasticity, suggesting gradual and modular evolution of reproductive plasticity.

Genome Report: Long read, high-coverage reference genomes of the Nymphalid butterflies Catonephele acontius and C. numilia (Nymphalidae: Biblidinae)

Withdrawal StatementThe authors have withdrawn this manuscript because in February 2026, the authors found that the Catonephele numilia specimen was misidentified and was in fact also Catonephele acontius. Thus, the data in the article describing the Catonephele numilia genome is invalid, as it in fact describes a second Catonephele acontius genome. This data invalidation has resulted in a loss of confidence in the results and conclusions reported in the article as far as they apply to Catonephele numilia. The data describing Catonephele acontius is not affected and remains valid. The authors are, therefore, retracting this article. All authors agree with the retraction. Therefore, the authors do not wish this work to be cited as reference for the project. If you have any questions, please contact the corresponding author.

First evidence for an Amazonian insect migration in the butterfly Panacea prola (Lepidoptera: Nymphalidae)

Insect migrations rival those of vertebrates in terms of numbers of migrating individuals and even biomass, although instances of the former are comparatively poorly documented. This is especially true in the worlds tropics, which harbor the vast majority of Earths insect species. Understanding these mass movements is of critical and increasing importance as global climate and land use change accelerate and interact to alter the environmental cues that underlie migration, particularly in the tropics. Here, we provide the first evidence for an insect migration for the nymphalid butterfly Panacea prola in the Amazon, the worlds largest and most biodiverse rainforest that is experiencing a shifting climate and rapid forest loss.
