Mayflies Make Presence Known Along Mississippi Riv

[The_Ancient]

MINNEAPOLIS How bad are the mayflies in Minnesota this summer?
So bad, snowplows were called out to clear the bug carcasses.

That's after a motorcyclist skidded out of control on a highway along the Mississippi River last week, because the bugs created a three-to-four-inch-thick layer on the road.

A sheriff in the area says the mayflies haven't been this bad since the mid '70s.

But the bugs could also mean good news. Environmentalists say mayflies are a sign of clean water.

I've seen videos of those things. They come up out of the water all at once, mate, die, and fall to the ground covering everything. I'm so glad I don't live there.
