Butterfly species around the world are changing where they live. New research by Warren Cornwall reported in Anthropocene magazine cites a new study (involving 1,758 butterfly species) showing they're moving habitats towards tropic countries due to factors such as habitat loss and climate change.
🦋 Species such as the the bright blue Godartiana byses is heading south in Brazil, as temperatures increase. Europe’s endangered Danube clouded yellow is losing habitat due to more intensive agriculture.
🏝️ Roughly 1 in 10 of the world's 19,000 species are now found in different areas to in the past. Most butterfly species are found in the hotspots of the tropics, which are rich in biodiversity. Of the species reported to have altered location, 80% expanded their range, showing up in new places including Brazil’s little Godartiana.
🌍 Climate change was linked to about 79% of butterfly movements (where scientists identified a reason). As temperature rise, some are moving to areas with more suitable conditions. These mass movements of butterflies around the globe highlight the need for conservation initiatives, the authors write.
🌳 Habitat destruction and agriculture are major causes of species losing parts of their range. Intensive farming can remove the plants and habitats butterflies need to survive. This is particularly harmful to species which already have small or limited habitats.
While butterflies are attention grabbing because of their beautiful colours and remarkable metamorphises, the alarm over the changes in their locations isn’t just about the insects. It's a sign something bigger is amiss: “Butterflies are early warning indicators,” said Chowdhury. “If their ranges are shifting this dramatically, it signals profound changes across ecosystems.”
