The method is suggested to calculate the virtual angular speed of turning from the measurements of turning tendency in tethered insects. For the regular patterns with periods of 15—120° the speed of turning exceeds that of the stimulus up to 80—100°/sec. The real landscape contains a wide band of low spatial frequencies exciting a strong optomotor reaction (OMR). In the models of real landscapes the speed of turning is 2—4 times higher, than that of the stimulus, for stimulus speed 1—30°/sec. Under these conditions the continuous turning could be compensated lo 70—80%. The OMR is most effective during small continuous rotation caused by slight asymmetry of legs or wings. At swift yaws the OMR fails to hinder the turning. During straight-line movement the OMR may be caused by the asymmetrical stimulation of eyes.
