Climate change is reshaping butterfly ranges worldwide. A global study found that 80% of 1,758 species in its dataset had expanded their ranges. @larspett.bsky.social and colleagues combined 6,182 reports from 105 countries. doi.org/10.1038/s415... #Biodiversity #ClimateChange #Ecology

🦋 Unusual boom in painted lady butterflies in Sweden, but global patterns have also been observed. A study of 1,758 butterfly species found that around 9 in 10 have shifted their ranges. Climate change, alongside land-use change and other pressures, is reshaping where butterflies can live.

In the last 120 years, we have lost over 50 species of native moths, and suspect many others are now at risk of extinction 🔴 This autumn, we're taking on a ‘moth-umental’ task to create the first-ever Red List for Britain’s macro-moths, and we need your help 👉 www.crowdfunder.co.uk/p/moths-matter

How 'parachute science' is failing the world's tropical insects
Monash University scientists have developed a global framework to tackle a major blind spot in biodiversity conservation: Insects underpin ecosystems and food production but remain largely invisible to conservation efforts across the tropics.

🦋 Most insect species live in the tropics, but our knowledge and conservation efforts are not. Our new BioScience paper shows why tropical insects remain overlooked and how local knowledge, citizen science and better monitoring can help close the gap. 🔗https://doi.org/10.1093/biosci/biag136

Climate change is causing widespread range shifts in butterfly species globally. Studies show that butterflies are shifting their ranges, expanding into new areas, and contracting in others, often in response to rising temperatures.

“Butterflies are early‑warning indicators and are signalling a warning across the entire planet. If their ranges shift this dramatically, it signals profound changes across ecosystems.” About 80% of butterflies expanded their ranges, often moving into newly suitable areas as temperatures rise.

80% butterflies have expanded their ranges while a quarter face range contractions due to climate change: Study
Butterflies globally are on the move across continents and new territories, shifting their ranges to adapt to the warming world and survive extreme weather events, according to a new study. The paper, published in the journal Nature Ecology & Evolution, assessed records for 1,758 butterfly species across 105 countries, representing nearly 10 per cent of the known diversity of these insects. The findings painted a complex picture of “winners” expanding into new territories and “losers” being pushed toward local extinction. The study noted that 80 per cent of the species experienced range expansions and nearly 79 per cent displayed range shifts to cooler regions associated with climate change and severe weather events. “‘Climate change and severe weather’ was reportedly associated with the horizontal range expansions of 163 species, the horizontal range contractions of 131 species and the elevational range shifts of 61 species,” the assessment said. According to the authors, a significant proportion of species — amounting to almost 27 per cent — showed contraction in their ranges while 22 per cent shifted along elevational gradients. The range shifting has been observed to be highest in Europe, making it a hotspot with countries such as Sweden, Finland, Spain, Luxembourg, and...
