This study investigates whether gregarious locusts (Locusta migratoria) can use social information from robotic demonstrators to optimize predator avoidance behavior. The research explores how different robotic demonstrators, with varying shapes and color patterns, influence locusts' responses, particularly their hiding behavior. The study used biorobotic demonstrators that mimicked the size, shape, and color patterns of locusts, as well as neutral demonstrators with simple elliptical shapes. The robotic demonstrators were placed on a rod, and their rotation was used to simulate a looming stimulus, prompting locusts to hide. The results showed that locusts responded more quickly and exhibited more hiding behavior when exposed to biomimetic demonstrators, especially those with gregarious-like color patterns. Color patterns and biomimetic shapes significantly influenced the locusts' responses, with biomimetic shapes having a more pronounced effect. The study highlights the role of social information in predator avoidance contexts and suggests that robots can serve as effective tools for social learning research. The findings contribute to understanding the complex behavioral ecology and social biology of invertebrates, and have implications for the development of social robotics and environmental management strategies.This study investigates whether gregarious locusts (Locusta migratoria) can use social information from robotic demonstrators to optimize predator avoidance behavior.
