In Ekaterinburg on a building site appeared dusty whirlwind, suggestive fear phenomenon was filmed by witnesses. However, this is not any accident in this region, 10 km South of Yekaterinburg, in the village of Bolshoy Istok, the "vortices" of swarms of mosquitoes.

Dusty vortex is called vortex motion of air that occurs near the surface when the ground is very warm. Such vortices, unlike the tornado, not associated with clouds and there are no more than a few minutes and their height can reach several tens of meters. They raise dust and small stones, but in rare cases can even pick up the car.

It involves Mature individuals, most often of the order Hymenoptera (which include bees, ants, wasps and bumblebees). Insects begin swarming with the aim of dividing the colony.
