The annual mayfly invasion emerged from the Mississippi Valley, around La Crosse, Wisconsin and densified into such a cloud that it was visible on the weather radar in the region.

Moreover, this dark cloud of flying insects triggered car collisions (two injured) and blacked out the sun changing day into night! Freaky!

Experts were however baffled by the size of this year mayfly swarm. But as you know, these flying mayfly insects are a positive sign for good water quality. Moreover, just as quickly as they emerge, the bugs die off in about a day after mating!
