Millions of mosquitoes form a 'mosquito tornado' in Russia; video viral

A video of millions of mosquitoes taking shape of a tornado in the Russian region of Kamchatka Krai has gone viral online. The man who filmed the video said he was driving right through the swarm. "There is nothing wrong here, they are male mosquitoes that...circle around one or several females in order to mate," entomologist Lyudmila Lobkova said.
