Last week a mayfly invasion nearly entombed the front door of our Eden Prairie news office. They are attracted to our lobby lights. The swarm of flies, which only lasts for a couple of days, rarely happens at the same time every year, but when they descend, it arrives with biblical intensity.
They target your ears, eyes and nose with no discernable pattern. A pair of gardening delivery guys were so engulfed, they began swatting and flailing as they carried bags of mulch back to their truck. The insects themselves are like specks of ash when you squash them. If those delivery guys came back this week, there would be no evidence of the summery insect’s existence.
