Bug Helmets: Treehoppers Detect Electric Signals

casualSTEM delivers brief and informative summaries of the latest science news every Saturday. Full of jokes, silly polls, and a cartoon!

Bug Helmets

Treehopper insect’s “helmets” have a shocking secret. Their pronotums house sensory organs that tap into bioelectric signals.

• Pronotum = helmet-like structure, varying widely across insect species

• Researchers observed treehopper behavior while playing various wasp signals

• Treehoppers ran from predatory signals and didn’t react to others

Electroception (detecting and reacting to electric stimuli) is rare among land animals. Further research could uncover deeper insect communication and inspire bio-sensors. Orrr high-tech bike helmets.
