Bug Swarm Causes Accident

Snowplows had to be called out in Minnesota, Sunday night.

However, the plows weren't dealing with snow this time.

An area around Hastings Bridge was swarmed by may flies, which covered the bridge.

Four inches of crushed bugs ended up being the result, causing an accident when one driver lost control on the slick surface, before the bridge was shut down.

Swarms of may flies are common near water, during the summer, and their attraction to light draws them to vehicles at night.

Accidents are not common from them, but authorities say they'd never seen a swarm so large before.
