Bumblebees Exhibit Adaptive Flapping Responses to Air Disturbances
Tim Jakobi, Simon Watkins, Alex Fisher, Sridhar Ravi

TL;DR
This study uncovers how bumblebees adapt their wing movements in response to air gusts from different directions, revealing specific kinematic strategies that improve flight stability in turbulent conditions.
Contribution
It provides detailed analysis of bumblebee wing kinematics during gust encounters, identifying adaptive responses that can inform robotic flight control in unsteady airflows.
Findings
Bumblebees adjust wing position based on gust direction.
Upward gusts cause coordinated posterior wing shifts.
Downward gusts increase flapping frequency and amplitude.
Abstract
Insects excel in trajectory and attitude handling during flight, yet the specific kinematic behaviours they use for maintaining stability in air disturbances are not fully understood. This study investigates the adaptive strategies of bumblebees when exposed to gust disturbances directed from three different angles within a plane cross-sectional to their flight path. By analyzing characteristic wing motions during gust traversal, we aim to uncover the mechanisms that enable bumblebees to maintain control in unsteady environments. We utilised high-speed cameras to capture detailed flight paths, allowing us to extract dynamic information. Our results reveal that bees make differential bilateral kinematic adjustments based on gust direction: sideward gusts elicit posterior shifts in the wing closest to the gust, while upward gusts trigger coordinated posterior shifts in both wings.…
