I was doing some reading Sunday night and I happened check Facebook when I saw a post from a friend of mine in La Crosse, WI. He had posted a screen grab of the weather radar and what appeared to be a line of showers along the Mississippi River-- except the image wasn't of rain, it was actually of tons of mayflies that had just hatched!

The Pioneer Press has the story HERE. But basically, the mayflies hatch in such huge numbers that the weather radar actually picks them up! Mayflies are harmless and only live about 24-hours. But they hatch in such large numbers that they build up on roads and highways and are a royal pain in the keester to clean up. And, according to the story, one woman actually was involved in a 3-car crash in Wisconsin, thanks to the build-up of mayflies on the road. They're so thick that snowplows are sometimes called out to clean them up.  Now, THAT'S a lot of bugs!

This time the mega-hatch was in La Crosse and Trempealeau in Wisconsin, but huge mayfly hatches have also occurred in Red Wing and Hastings. I've never witnessed such a phenomenon, and I'm fairly certain I don't want to!
