May they fly away one day soon, but today mayflies are among us. Some are calling it an "invasion," but it's the time of year where cities and states near the Great Lakes region experience a repulsive visitation.

When an excessive amount is swarmed together, mayflies look like a thick large patch of dirt, and can be spotted on weather radars.
