Butterflies are adapting fast to climate change, but even their super-evolution skills have limits! Scientists in Sweden found that wall brown butterflies can speed up their growth and nail winter timing as they move north, but freezing winters still stop them from going further. Turns out, evolution can’t outsmart every climate challenge. Why does it matter? Knowing these limits helps predict which pollinators (and pests!) might move as the planet warms.
