"For a second I thought it was snowing!" one commenter wrote.

Another added: "That looks like a whole bunch of NOPE."

According to the University of Iowa's State Hygienic Laboratory, the bothersome bugs are actually an "important part of Iowa's aquatic insect fauna" and "valuable in determining water quality."

"Mayflies spend most of their life as aquatic larvae or nymphs," the lab's website says. "Usually they can be found on bottom substrates of rivers, streams and lakes around the state."

Still not a fan? Well, their adult lifespan is only a few days long, so they'll be gone soon.
