The researchers determined that caterpillars detect electrostatic fields with bristly fibers on their bodies, which vibrate in response to electrical stimuli from approaching wasps.
Caterpillars exhibited unique defensive behaviors when exposed to a fake electrical field mimicking a wasp's approach, showcasing their ability to sense these fields for survival.
The study showcases the first documented predator-prey interaction on land using electroreception, highlighting how terrestrial animals might combine this sense with others for enhanced awareness.
Sam J. England emphasizes that for terrestrial animals, detecting electrostatic fields can significantly enhance the sensory picture of predator presence, integrating with other senses.
