The masses of insects were filmed swirling over a river in Pune, India.
Experts have attributed it to untreated sewage.
Retired zoology professor Hemant Ghate told local media: “These insects are abundant in waters polluted with organic matter and are present everywhere on the Mula-Mutha River.”
Local Rakesh joked: “Thanks, Pune Municipal Corporation, for giving gift of mosquitoes tornado to Keshav Nagar Pune residents in return for their timely municipality tax payments.”
Sourav added: “I have seen it.
“First I thought it was smoke during late evening hours.
“This is a serious concern of health.”
And another person said: “This looks like something straight out of a movie.”
Prof Ghate said the insects do not bite but their abundance suggests sewage-polluted waters.
He added: “On a still day with no wind, the swarms appear as a plume of smoke coming from trees or buildings near the river.”
