A computational model of stereoscopic prey capture in praying mantises

Sensitivity of mantis striking behaviour to stimulus size and stereoscopic distance.
(A) Data from [10], available at http://dx.doi.org/10.1098/rstb.2015.0262. Species was Sphodromantis lineola; stimuli were on a computer screen 10cm from the insect; nearer distances were simulated using coloured filters. (B) Data extracted from Fig 5 of [36] using WebPlotDigitiser (https://apps.automeris.io/wpd/). Species was Sphodromantis viridis; stimuli were on a computer screen 5.5cm from the insect; nearer distances were simulated using base-out prisms. Note that in this figure, we plot the strike rate, i.e. the probability that a given trial elicits striking behaviour (since this was what was available for [36]). In [10], some trials elicited several strikes. The peak strike rate in A, 0.49, is lower than the peak of the mean number of strikes, plotted below in Fig 9.
