Mayfly Swarm Causes 3 Motorcycle Accidents

It was a scene straight from a nightmare. A town in Pennsylvania was invaded by swarming mayflies on Saturday night, causing three separate motorcycle accidents and closing a bridge for several hours, fire chief Douglas Kemmerly told ABC News today. The Wrightsville Fire Department responded to a motorcycle crash along the Veterans Memorial Bridge between the towns of Columbia and Wrightsville. Firefighters and police were bombarded by nickel-sized mayflies that turned the sky into a “blizzard,” Kemmerly said.
