Investigating the stimuli that elicit dynamic defensive displays can indicate when throughout the predation sequence prey are likely to perform them. This is crucial to understanding whether these displays function as classic deimatic 'startle' displays, facultative aposematism or aid in facilitation of predator learning. We investigated the triggers of defensive display in three different praying mantis species found in eastern Australia; Archimantis latistyla, Hierodula majuscula and Pseudomantis albofimbriata. Dynamic displays in praying mantises have been described as 'deimatic' and given the risks inherent in sustaining an attack, especially as mantises are not chemically defended, we predicted that mantises would perform their displays to stimuli that simulate early cues of predation. In a randomised order, we exposed each mantis to five different stimuli simulating a nonspecific predator, including tactile and non-tactile stimuli. All species performed their display in response to tactile stimuli however A. latistyla and H. majuscula were more likely to respond than P. albofimbriata. The smallest species, P. albofimbriata, did not readily respond to simulated attacks and was the least likely to perform a display. Our results do not meet the prediction that mantises should respond to stimuli that correspond with early stages of the prédation sequence. This raises questions surrounding the utilisation of defensive displays in non-chemically defended prey and contributes to our understanding of predator-prey dynamics during the prédation sequence.
