Scientists from the University of Exeter discovered a massive migration of over 17 million insects passing through a narrow 30-meter stretch in the Pyrenees mountains. Lead researcher Will Hawkes described the spectacle as extraordinary, with days recording over 3,000 flies per meter per minute. This migration is crucial for biodiversity and pollination. This groundbreaking study highlights the importance of migratory insects and the role they play in ecosystems. The research revealed that millions of insects make these seasonal journeys, underscoring the need to understand and protect these vital populations.
