...Nellie Linander; Marie Dacke; Emily Baird ABSTRACT When flying through narrow spaces, insects control their position by balancing the magnitude of apparent image motion (optic flow) experienced in each eye and their speed by holding this value about a desired set point. Previously, it has been...

... be varied. Manipulation of pattern motion revealed that the speed of flight is controlled by regulating the image motion that is experienced by the eyes. Flight speed is surprisingly robust to changes in the contrast and/or spatial texture of the visual environment, suggesting that the underlying movement...

...M. V. Srinivasan; S. W. Zhang; N. J. Bidwell ABSTRACT The ability of honeybees to gauge the distances of short flights was investigated under controlled laboratory conditions where a variety of potential odometric cues such as flight duration, energy consumption, image motion, airspeed, inertial...

...Miriam Lehrer ABSTRACT In a series of behavioural studies we found that bees use depth information extracted from self-induced image motion in several visual tasks involving pin-pointing the goal. Some of the results are reviewed here in an attempt to emphasise the active nature of this performance...

.... the evaluation of retinal image motion for distance estimation, has been demonstrated here. This would put mantids in the company of some other insects that are generally believed to use movement parallax in spatial orientation (e.g. locusts, Collett, 1978 ; Sobel, 1990 ; Collett and Paterson, 1991...
