Swarm of Mayflies Invade Ohio

It’s like the modern-day equivalent of the biblical plague of locusts invading Egypt: : mayflies have invaded Ohio. The swarm of mayflies was dense that a weather radar was able to capture it. CNN World has the details: 

These mayflies come from the waters of Lake Erie.

They won't be around for long, though. Individual mayflies live up to two days once they come on land. The swarms typically last about a month.

Ohio Sea Grant dispels the fear of a plague, telling the residents that the swarm is nothing but a good indicator and wouldn’t disturb them for long: 

Residents may find them annoying, but the mayfly swarm is an indication of good water health in the Great Lakes.
