Butterfly ranges shift worldwide amid climate change, with most species expanding their reach

A global analysis of range-shift records for 1,758 butterfly species—10% of known butterfly species—found that 80% had expanded their range and that 79% of all recorded range shifts were linked to climate change and extreme weather events. The new study, published in Nature Ecology & Evolution, also reports range contractions for 27% of species, and 22% of s

The top 3

  1. Top 3 Butterfly Species with Significant Range Shifts: Climate change is driving notable range expansions and rapid shifts in several butterfly species globally, making them key indicators of environmental change.
  2. Top 3 Regions Most Affected by Butterfly Shifts: Butterfly range shifts are occurring on every continent, but some regions, particularly in Europe and mountainous areas, show more pronounced and well-documented changes.
  3. Top 3 Ecological Impacts of Butterfly Range Shifts: Butterfly range shifts, while often an adaptation to climate change, can lead to complex ecological consequences, affecting plant-pollinator interactions, species competition, and food web dynamics.
