Drosophila melanogaster rely on wide-field optic flow fields to detect perturbations from their flight path. Previous research has identified that flies will shift their attention forward during forward flight to discount lateral portions of their visual field that are too noisy due to motion blur. The loss of these large regions of the visual field may be costly to navigating flies. For instance, distinct optic flow fields can have small regions which are highly ambiguous. If flies can sample the optic flow field over the entire visual field, these ambiguities can be reduced. We investigated the effects of restricted-area optic flow fields on fly steering errors. We also looked at which restricted-area regions resulted in the smallest steering errors.
