What happened

Butterflies are on the move as the planet warms: New research Swati Mestri Scientific Editor Andrew Zinin Chief Editor Imagine spotting a butterfly species in your garden that you have never seen before.

Why it matters

You might take a photo and upload it to a citizen science app or tell a local nature group about your new encounter.

Common ground

But if that butterfly has appeared in your backyard because its old home is becoming too hot, too dry or too damaged, the sighting is more worrying.
