Why do treehoppers look so weird?! Our latest paper, out this week in @pnas.org, suggests a perhaps unexpected reason - static electricity ⚡ We show that treehoppers can detect the electrostatic cues of predators and that their crazy shapes may boost their electrosensitivity! doi.org/10.1073/pnas...

In some species, the function of the treehopper's pronotum (the body part that forms the crazy structures) is intuitive - for example, there are species that look like thorns, which presumably helps them hide from predators or injure attackers. But in many species, a function is not obvious...
