(AP Photo/Carolyn Kaster)Inside trees are sugary, nutrient-heavy saps that flow through tissue called phloem. Most insects love the sap. But not cicadas — they go for tissue called xylem, which carries mostly water and a bit of nutrients.And it’s not easy to get into the xylem, which doesn’t just flow out when a bug taps into it because it’s under negative pressure. The cicada can get the fluid because its outsized head has a pump, said University of Alabama Huntsville entomologist Carrie Deans.

They use their proboscis like a tiny straw — about the width of a hair — with the pump sucking out the liquid, said Georgia Tech biophysics professor Saad Bhamla. They spend nearly their entire lives drinking, year after year.“It’s a hard way to make a living,” Deans said.
