Insect Vision: Judging Distance with Binocular Motion Disparities.
Curr Biol. 2018 Feb 19;28(4):R148-R150
Authors: Ruiz C, Theobald J
Praying mantises, like humans, calculate distance by triangulating angular disparities of corresponding image regions between their eyes. New work shows they can do this using just dynamic luminance changes, and thus judge distance in scenes that we see as flat.
