It's simple: the more bug guts stuck to airplane wings, the harder it is for planes to fly. Squished bugs create drag, which means the planes need more fuel to get to where they're going, and fuel is expensive. Getting bugs off plane wings could save .5% of fuel costs, which is $240 million in the plane industry. 

Solutions that scientists, including NASA, are considering include Teflon-coated wings or a wing extension that protects the wing itself from insects. 

Nixing the bugs would be a boon for the environment as well. "When you burn less fuel, the engines require less maintenance. We produce less emissions. There's less carbon dioxide," Mike Sinnett, Boeing's vice president for product development, said. "Across the board, burning less gas is a good thing."
