Ants tending treehoppers for honeydew in Ecuador

These yellow treehopper nymphs and black and white adults were filmed in the Amazon rainforest of Ecuador. They feed upon sugar containing sap of a plant. Excess sap is excreted as honeydew which is collected by ants that feed upon the sugar and, in return, protect the treehoppers from predators. This is an example of mutualism, a form of symbiosis where both species benefit.
