Butterflies That Migrate Across Continents and Their Incredible Journeys

Every year, millions of butterflies embark on journeys that rival the migrations of birds and whales. Despite their delicate wings and lightweight bodies, these remarkable insects travel hundreds or even thousands of kilometres in search of warmer climates, breeding grounds or fresh food sources. Their migrations span mountains, forests, deserts and even seas, often involving several generations before the journey is complete. Scientists are still uncovering the secrets behind these extraordinary travels, including how butterflies navigate without maps or previous experience. Their incredible endurance challenges our assumptions about insects and highlights one of nature's most fascinating seasonal spectacles.
