A remarkable dragonfly migration stretching between 14,000 and 18,000 kilometers has been discovered which spans the Indian Ocean.

The migration is by far the longest known insect migration, dwarfing the 7,000km journey of monarch butterflies. Millions of dragonflies make the epic migration every year, which spans from India to the Maldives, the Seychelles, Mozambique, Uganda and back again.

Perhaps the only thing more amazing than the migration is that it has somehow dodged scientific discovery until now. “This just illustrates how little we still know about the natural world,” said Charles Anderson, discoverer of the mass migration.

A groundbreaking study has proved that man-made light sources can change natural light cycles, triggering abnormal animal behavior that often leads to injury and even death.

The study, published in the journal Frontiers in Ecology and the Environment, confirms that polarized light pollution can cause confusion in creatures that rely on light ‘cues’ to navigate through their environment, with many animals also thrown off course by light reflecting from buildings.
