Firefly phase curves inform decentralized coordination

Researchers measured how male Photuris frontalis change their flash timing in response to an external blinking LED and derived a phase‑response curve that predicts when individuals speed up or delay flashes. The result explains how local, timing‑based adjustments can propagate into whole‑group synchrony in dense aggregations. — Understanding this simple, measurable coordination rule has cross‑disciplinary implications for designing decentralized timing protocols in swarm robotics, sensor networks, and for interpreting collective behavior in ecology and social systems.
