Red List of European Butterflies 2025

A fully updated Red List of European butterflies was completed by researchers from BC Europe in 2025, in association with the International Union for the Conservation of Nature (IUCN). Species accounts for all the 442 European species evaluated can be found on the IUCN website.

A summary will be published in autumn 2025 and will be included on this page as soon as it is available.

Many new species have been added to the Red List due to the impact of climate change on their habitats, including Boloria freija (Freija's Fritillary) found in the far north of Scandinavia.
