ENTOMOLOGY - SPOTTY WINGS MAKE MONARCH BUTTERFLIES MORE AERODYNAMIC
BBC Science Focus
|July 2023
New research shows that the butterflies fly better when they have more spots on their wings
-
Monarch butterflies with more white spots on their wings are able to survive longer migrations, according to scientists. A study conducted by ecologists at America's University of Georgia, Athens, focused on the butterflies - which migrate thousands of kilometres every year to reach their wintering destination found that evolution favours spottier specimens.
It's not yet clear exactly how the spots aid migration, but the authors' conjecture is that they change airflow patterns around the butterflies' wings.
