Instanz: TeilenTeilen:The scale of butterfly range shifts is far greater than previously known — affecting every continentDr. Volker Hahn Abteilung ImpactDeutsches Zentrum für integrative Biodiversitätsforschung (iDiv) Halle-Jena-Leipzig05.08.2026 11:00A new global study shows butterflies are on the move as the climate warms, with far more species expanding their ranges than contracting.
Because many species exhibited multiple types of range shift, the percentages for expansions, contractions, and elevational changes is above 100%.
Insufficient monitoring leaves many gapsThe study also makes clear that countries differ greatly in how well butterfly range shifts are being documented.
For example, in some European countries, like the Czech Republic, Finland, Luxembourg, Spain, and Sweden, records exist for more than half of the countries’ butterfly species.
