Summary1.In the blowflyCalliphora flying stationarily in a wind tunnel, compensatory head movements were elicited by rolling the fly about its longitudinal axis (Fig. 1). Responses were recorded on video tape, and evaluated by single frame analysis.2.Active head movements were observed in response to visual and mechanosensory stimuli (Fig. 2). They are not made or caused by the head's inertial momentum (Fig. 11).3.Gravity, used by walking flies to align their head with the vertical, does not… 

The halteres of the blowfly Calliphora

Compensatory head reactions of flies to imposed body rotations in yaw, pitch and roll are quantitatively analysed and the haltere is characterized as a sense organ for maintaining equilibrium as well as a method to mimick rotational stimuli by subjecting the body of a flying fly to vibrations.

Structure and kinematics of the prosternal organs and their influence on head position in the blowfly Calliphora erythrocephala Meig.

The results show that the prosternal organs of Calliphora sense pitch and roll turns of the fly's head, and control at least its roll position.

Compensatory head rolling during corrective flight steering in locusts

Locusts (Locusta migratoria) flying under open-loop conditions respond to simulated course deviations with compensatory head movements and with steering reactions of wing muscles with significant significance for course control.

Locust flight steering

It is proposed that neck proprioception assists visual and acoustic information in adaptive flight steering in closed-loop corrective steering and during avoidance steering opposite head movements may in turn favor steering overshoot.

Locust flight steering

Results show that head movements, in addition to their generally accepted role in vision improvement, also contribute to the precision and temporal coordination of correctional flight manoeuvres.

From these considerations it is concluded that Coriolis forces play the major role in detecting body rotations.

How do hoverflies use their righting reflex?

It was observed here for the first time that hoverfly reorientation is entirely achieved within 6 wingbeats at angular roll velocities of up to 10×103 deg s−1 and that the onset of their head rotation consistently follows that of their body rotation after a time lag of 16 ms.

Control of moth flight posture is mediated by wing mechanosensory feedback

The results indicate that, in addition to their role as actuators during locomotion, insect wings serve as sensors that initiate reflexes that control body dynamics, suggesting that the wings can encode information about flight dynamics.

The role of wing mechanosensory feedback in insect flight control

Results demonstrate that the wings can provide information about body dynamics during locomotion, a role previously thought to be the sole domain of the halteres, and support the wings’ role as context-dependent sensory structures.

Integration of visual and antennal mechanosensory feedback during head stabilization in hawkmoths

This study suggests that head stabilization in moths is mediated primarily by visual feedback during roll movements at lower frequencies, whereas antennal mechanosensory feedback is required when roll occurs at higher frequency, consistent with the hypothesis that control of head angle results from a multimodal feedback loop that integrates both visual and antennale mechanosENSory feedback, albeit at different latencies.



Compensatory head roll in the blowfly Calliphora during flight

Video records were made of the blowfly Calliphora erythrocephala L. mainly during tethered flight in a wind-tunnel, to study its movements about the longitudinal body axis (roll), and the limits of fly vision and the advantages of compensatory head movements for different visually guided behaviour are discussed.

Positional head reflexes and the role of the prosternal organ in the walking fly,Calliphora erythrocephala

The prosternal organ (PSO) is part of a control system that stabilizes the position of the head relative to the thorax against mechanical disturbances, but it is insensitive to passive movements of theHead around the transverse axis of the fly.

Free flights including both intact and deafferentated animals made possible an evaluation of the importance of the different groups in stability reactions, and it was shown that control of angular movement is accomplished by the forewing groups only, especially the proximal ones.

Head Movements in Flies ( Calliphora ) Produced by Deflexion of the Halteres

Behavioural observations of walking flies show that the presence or absence of halteres has a small but nevertheless significant effect on the animals9 ability to detect angular accelerations during walking or to orient with respect to gravity.

An analysis is given of the aerodynamic and elastic properties of the mechanical system which transfers air current to act as stimulus on the mechanoreceptors in the antennae.

Locusts behave as if there is a spatial representation of theVisual area in the central nervous system and always turn so that the horizon is horizontal and the brighter half of the visual field uppermost in this representation.

Analysis of the photographs shows that the wing movements act to counter the imposed angular accelerations and that during sinusoidal oscillations about the vertical axis, head turns are in antiphase with angular acceleration.

On head and body movements of flying flies

Two main points emerge from the analysis: changes in body direction and head direction occur simultaneously in almost all cases and active neck movements are initiated together and in the same direction of body movements.
