If you thought running into a swarm of insects was bad, you've probably never come face to face with a bug tornado.

This month, The Weather Network captured footage of a vortex of pesky insects swarming parts of Ontario.

In a video shared from Mississauga on May 12, hundreds of gnats can be seen spiralling in what appears to be a tornado-like fashion. A similar incident was captured at Point Pelee National Park on May 15.

According to the Farmers' Almanac, a "bugnado" is "simply a swarm of insects in the middle of a mating duel, where the male insect attempts to swoon the female."

During this time, the bugs can actually create funnels that look like they belong in a horror movie. It is important to note that while they may look terrifying, the swarms are generally harmless. However, they can sometimes pose a danger to drivers due to the low visibility that they can cause.
