Planthopper bugs may be small, but they attract mates from afar by sending vibrational calls along plant stems and leaves using fast, rhythmic motions of their abdomen. In a new study publishing March 12 in the open-access journal PLOS Biology, researchers at the University of Oxford show how a newly-discovered “snapping organ” enables courting bugs of both sexes to produce this shaking motion through a combination of muscle action and elastic recoil.
