The survival of the glacial relict butterfly Boloria eunomia is positively affected by warming during its egg, pre-diapause larva, and pupal stages, whereas the overwintering larva is negatively affected. The map shows differences in local climate velocities between annual and the overwintering season (September to March), calculated from monthly mean minimum temperatures between 1975 and 2050 under the RCP8.5 high-emission pathway. Reddish and/or bluish values indicate locations where overwintering thermal conditions are shifting slower and/or faster than annual means (from Fig. S3 in Brito-Morales et al. 2018).
