There are thought to be about 17 quadrillion flies alive on Earth at any one time. That’s 17 million for every living human.

They’re predators and parasites and pests, but they’re pollinators too. They help us solve crimes, heal wounds, and understand genetics and evolution. And they literally help at least one artist paint his paintings.

Also this hour: A look at David Cronenberg’s 1986 remake of The Fly on the week of its 35th anniversary.
