|Title:||Honeydew flicking by treehoppers provides cues to potential tending ants|
|Abstract:||The honeydew-producing treehopper, Guayaquila xiphias, is frequently tended by ants on shrubs of Didymopanax vinosum in the Brazilian savannah. Field experiments showed that the flicking of accumulated honeydew by untended treehoppers provides cues to ground-dwelling ants. Upon finding scattered honeydew droplets on the ground, the ants climb onto the host plant and start tending activity. Honeydew-soaked filter papers placed beneath unoccupied host plants induced significantly more ants to climb onto the plant than water-soaked papers. Because predation and parasitism on G. xiphias can be severe at early stages, and tending ants protect the homopterans against predators and parasitoids, the capacity to attract ants early in life can be crucial for treehopper survival.
