Popis:	The hearing system of the katydid genus Neoconocephalus functions in two contexts: intraspecific communication and predator (bat) avoidance. Male calls and bat echolocation signals differ spectrally and temporally. In order to respond appropriately, katydids must recognize and discriminate between signal types. We categorized bat avoidance behaviors and examined temporal recognition of bat cries behaviorally during tethered flight in Neoconocephalus retusus and Neoconocephalus ensiger. We used simulated bat approaches to categorize bat avoidance behaviors in Neoconocephalus. Four distinct behaviors were observed: steering, wingbeat interruption, dives and leg kicks. The first three behaviors were amplitude dependent and could be elicited by a single pulse of ultrasound. The final behavior only occurred during the terminal phase and was found to be pulse-rate dependent. Response probabilities of specific behaviors varied between species, A comparison of the two Neoconocephalus species showed that ...
