The paper shows that optic flow-processing interneurons in butterflies increase baseline spiking activity during wing flapping and phase-lock to the wing-beat cycle, suggesting suppression of self-generated visual motion signals.

This study quantifies how gaze stabilisation limits motion blur in freely flying Monarch butterflies, showing that thoracic oscillations broaden the effective photoreceptor acceptance angle, degrading spatial acuity.

This study shows that wing mechanosensation modulates optic-flow-sensitive descending neurons in butterflies by altering excitability and timing, not visual feature encoding.

The paper investigates spectral sensitivity in butterfly motion-vision pathways, finding that pre-motor neurons have distinct spectral responses related to their functional roles in flight control.

This study shows that Drosophila adjusts flight speed through adaptive feedforward control, not just feedback, by observing changes in speed after wing damage and antennae ablation.

The paper shows that blowfly motion vision is tuned to maximize signal energy transfer between mechanical input and sensor output, improving observability and controllability.

The paper develops a device to generate moving polarised light patterns for insect vision studies and tests its effectiveness on butterfly and blowfly photoreceptors and neurons.

The paper shows hoverflies use passive inertial damping in their head anatomy to stabilize gaze during high-speed flight, unlike blowflies and horseflies which rely on sensory feedback.

This study identifies novel fly visual cells that encode translatory optic flow and depth during motion, contributing to navigation in cluttered environments.
