Data for: Clear effects of population and sex but not rearing temperature on stress tolerance in a temperate butterfly

With temperatures rising globally due to climate change, an organism’s survival depends both on its direct tolerance to rising temperatures and its tolerance to indirect effects of warming, such as resource shortage. Genetic background and phenotypic plasticity in the form of acclimation are known to affect stress tolerance, but much about genetic variation in plasticity is still unknown, especially in insects other than Drosophila. Here we aim to study the effect of population of origin, developmental temperature, and their interaction on heat and starvation tolerance. We test the beneficial acclimation hypothesis and how it is influenced by intraspecific differences. For this, we reared Glanville fritillary butterfly (Melitaea cinxia) larvae originating from Finland, where the climatic conditions experienced are relatively cool, and Spain, where the climate is relatively warm, at high and standard temperatures. In the adult stage, we measured stress tolerance as the time until heat kn..., , , # Data for: Clear effects of population and sex but not rearing temperature on stress tolerance in a temperate butterfly

## Description of the data and file structure

Data on a rearing experiment in *Melitaea cinxia* performed on two populations at two temperatures, with three adult treatments. The experiment was performed in autumn 2021 in Helsinki, Finland, by Nadja Verspagen
