Head points midway between the targets prior to tracking and the seeing eye of seven mantids views either a pair of simple targets (a) (n = 115 saccades) or a simple and a complex target (b) (n = 156 saccades). Arrows at bottom of histograms show mean head angles when only the left or the right target is presented.
