Experts have been flummoxed by the appearance of globe skimmer dragonflies, a wide-ranging species that is present on every continent except Antarctica.
One theory is that the country’s recurring heat waves brought them to Jeju Island, though why they congregated there en masse remains a mystery.
In footage aired by the island’s local broadcaster JIBS on Tuesday, countless dragonflies can be seen swarming a fishing vessel sailing three kilometers (1.86 miles) offshore at dawn on Sunday.
“I have never seen so many bugs flying into the vessel,” the captain told JIBS. He estimated that he saw “thousands or tens of thousands” of dragonflies that morning.
He added he was “unable to properly conduct fishing operations because the dragonflies landed on his body and face” and “wreaked havoc.”
The JIBS reported sightings of dragonfly swarms on the island have increased since they migrated south at the end of summer on the peninsula.
Prof. Kim Dong-soon from Jeju National University’s Plant Resources and Environment Department noted that previous dragonfly swarms “would have been documented if they had taken place on land before.”
But Kim added that people should not be too worried by the dragonflies as they are “harmless.”
“They consume flies and mosquitoes, so they should be considered beneficial insects,” he noted.
