Abstract

AimAllochronic speciation occurs when sympatric populations sharing similar feeding regimes diverge because they mate at different times. Such speciation mode is fascinating because it permits the study of subsequent adaptations and/or geographic range shifts undergone by the populations that face new ecological constraints. Moreover, exploring whether intraspecific differentiation is accompanied by niche divergence is crucial for planning efficient biodiversity management and invasive species control. Here, we address the topic of potential climatic niche divergence between two sympatric populations of the pine processionary moth Thaumetopoea pityocampa (PPM) that diverged under allochrony. The larval development of a PPM population recently discovered in coastal regions of Portugal, referred to as the summer population (SP), occurs in the spring-summer instead of the autumn-winter as for all other populations of this species.
