First leaf-to-leaf duet
Grapevine leafhoppers, known to whisper sweet nothings by sending vibrations through plant stems, can also blow kisses to a potential mate on another plant. Even though their leaves sprang from separate cuttings, a Romeo and Juliet of grapevine leafhoppers buzzed a duet across a chasm of 6 centimeters. This feat represents the first experimental result showing that insect vibrations can buzz from plant to plant, researchers in Italy and Slovenia report online May 5 in PLoS ONE. Now researchers want to know how the insects accomplish the duets. —Susan Milius
