We used computer-generated stimuli to assess the stimulus parameters eliciting prey-directed behaviors in four mantis species: Rhombodera basalis (60 mm body length), Deroplatys lobata (70 mm), Hierodula membranacea (80 mm), Miomantis sp (38 mm). All responded appetitively to erratically moving disks subtending 10° or more. R. basalis responded more consistently to checkered (versus solid black) disks; only D. lobata displayed a size preference (14–23 deg disks); Miomantis sp. struck at disks as large as did the largest species; only Miomantis sp. displayed approaching behavior. H. membranacea and R. basalis preferred black disks on a white background (versus the reverse), and red disks (versus blue or green) on a brightness-matched grey background. All preferred elongated stimuli moving parallel (versus perpendicular) to their long axes.
