Billions of Insects Migrate Annually Through Pyrenean Mountain Pass

Research reveals a critical migration route for diverse insect species, highlighting their ecological importance and the threats they face.

Scientists tracked 17 million insects migrating through a 30-meter-wide pass over four years.
The insects include pollinators, pest controllers, and decomposers, crucial for ecosystem health.
The migration supports genetic diversity in plants and provides food for birds.
Climate change and habitat loss threaten these vital migratory patterns.
Researchers emphasize the need to protect insect habitats to maintain ecological balance.
