Happy #WorldSwallowtailDay!
We are excited to launch our "Swallowtail of the Month" feature in celebration of today, but acknowledging that for many of us, World Swallowtail Day is EVERY day!
If you have a favourite swallowtail, let us know. We would like to feature your favourites too!

Great yet alarming work by @pro-pink.bsky.social & collaborators! Time to increase our efforts to assess, plan and ACT for (especially mountain, but also all) butterflies!
A major milestone of our >4-year effort to bring #butterfly diversity and its threat to global attention. We show most species and hotspots cluster in mountains, with #climatechange projected to erode up to 67% of the thermal niche supporting this diversity. www.nature.com/articles/s41...

🚨"We project that up to 64% of the temperature niche space of butterflies in tropical realms will erode by 2070" thus turning mountains - known centers of butterfly diversity - from refugia to traps for butterfly diversity.
Another sobering outlook for butterflies! www.nature.com/articles/s41...
