Tremendous Mayfly Hatch Visible on Radar, Captured in Stunning Photos

A summer mayfly hatch on the Minnesota-Wisconsin border was biblical in proportion.

Watch this video showing images from a huge mayfly hatch on July 20, 2014, and check out the weather radar shot too.

The video was uploaded by DAHBOO77 and published on YouTube.

Those are some incredible images, and you know the fish in and around the Mississippi were having the feast of a lifetime!

The National Weather Service Weather Forecast Office released more information, and said that "the emergence of mayflies from their river bottom mud dwelling can occur at various times through the warm season depending on the species, [and] this particular emergence was that of the larger black/brown Bilineata species."

An official Pierce County news release, published on, suggested the mayfly swarm may have been the cause of a three car crash that sent one driver to the hospital.

Though mayflies are generally harmless to humans, with no biting or stinging capabilities, their 24-hour lifespans can still cause trouble. The swarms create clouds of bugs, and as they die off across roadways, driving becomes a slippery situation.

Here are some more images from the Wisconsin and Minnesota areas.
