Mosquito Clouds

About 830,000 individuals were murdered by mosquitoes in 2018. That was a decrease from earlier figures, which typically hovered around two million annually. And even if they are not a source of diseases like malaria, mosquitoes are bothersome at the best of times. Therefore, picture how upsetting it would be to come upon a pile of them that is so large it blocks out the sun.

A mosquito swarm turned into a tornado-like cloud in Russia in July 2021, darkening the sky. Millions of male mosquitoes in the pillar-like swarms are competing for the attention of a much smaller population of female insects. It's actually a rather typical occurrence, and the size of the swarms can change from year to year depending on the weather.
