Bizarre rainforest insect resembles a helicopter

This is a treehopper from the Amazon rainforest of Ecuador. Treehoppers are insects related to cicadas and leafhoppers. Most treehoppers have a highly modified pronotum on the back, in this case forming five hairy globes and a long spine, probably serving to deter predators. Treehoppers feed on plant sap which is rich in sugar.
