A swarm of supersized dragonflies invade Misquamicut Beach in Rhode Island.
Beachgoers were seen ducking for cover while others tried swatting them away as the swarm took over the beach.
The insects can travel in swarms of billions, so large that the swarms can show up on radar systems.
Experts say the insects swarm like this while breeding in the summer or when smaller insects they eat are thrown in the air by weather disturbances.
