In the tri-states we know all too well about this! Northeast Ohio’s lakeshore was overrun with swarms of mayflies last week, with the insects covering practically everything in sight. The swarms were so dense on Wednesday night that they actually showed up on weather radar as a large mass over Lake Erie. The outcome of the swarming insects could be seen the next day, when photos surfaced of two cars and a parking lot completely covered in the dead mayfly carcasses. They say that the mayflies emerge from the depths of Lake Erie, with their winged-stage only usually lasting for around two days before they die. Nothing like getting the snow shovel back out to shovel fish food.
