A video has recently appeared on YouTube showing an unexpected scene on a beach in the United States.

In Westerly, on the southwest coast of Washington State, a swarm of swimmers was caught off guard by a flock of dragonflies.

The video, which is currently going viral, is already enjoying great success on social media: it has already been viewed by millions, and many netizens are confused by the scene.

“When you are on the beach, suddenly a dragonfly apocalypse occurs,” the author captioned the post. According to him, the dragons appeared suddenly, and the swarm consisted of several thousand of the mentioned insects.

Otherwise, dragonflies are considered very useful insects that feed on mosquitoes. One wasp can eat more than 100 mosquitoes in a day, which is very nice to have near the house.
