Cicadas might be a mere inch or so long, but they eat so much that they have to pee frequently, emitting jets of urine, according to a new paper published in the Proceedings of the National Academy of Sciences. This is unusual, since similar insects are known to form more energy-efficient droplets of urine instead of jets. Adult cicadas have even been known to spray intruders with their anal jets—a thought that will certainly be with us when "double brood" cicada season begins in earnest this spring.
