The horrifying moment ‘tornadoes’ of mosquitoes blotted out the sun in a Russian region over the weekend has been captured on video. Thick, fast-moving pillars made up of millions of insects were seen on the eastern coast of Kamchatka, wreaking havoc among the locals. From a distance, pictures from the region appeared to show a cluster of tornadoes swirling dust and dirt into the air. But when filmed from within the clouds, the footage showed that the tornadoes are actually made up of millions of the unwelcome insects.
