Coordinated movements of the head and body during orienting behaviour in the praying mantis Tenodera aridifolia
چکیده انگلیسی

The visual orienting behaviour towards prey in the free-moving mantis was investigated with a high-speed camera. The orienting behaviour consisted of head, prothorax, and abdomen rotations. Coordinated movements of these body parts in the horizontal plane were analysed frame-by-frame. Rotations of these body parts were initiated with no or slight (≤40 ms) differences in timing. The initiation timing of prothorax-abdomen rotation was affected by its initial angle before the onset of orienting. There were positive correlations in amplitude among head-prothorax, prothorax-abdomen, and abdomen rotations. The ratio of these rotations to total gaze rotation was affected by the initial prothorax-abdomen angle before the onset of orienting. Our data suggest that coordinated movements of the head, prothorax, and abdomen during orienting are ballistic events and are pre-determined according to visual and proprioceptive information before the onset of orienting.

.Highlights► The visual orienting behaviour towards prey in the mantis was analysed. ► The orienting behaviour consisted of head, prothorax, and abdomen rotations. ► There were linear correlations in amplitude among these rotations. ► The ratio of these rotations to total gaze rotation was affected by the initial posture of the mantis.
