“…Calling songs have been described for many katydid species across the world, and the acoustic properties of these calls are extraordinarily diverse (Ragge and Reynolds 1998, Naskrecki 2000, Rentz 2001, Diwakar and Balakrishnan 2007a, Cole 2010, Cheng et al 2016, Chamorro-Rengifo et al 2018, Sevgili et al 2018. Similar to crickets (Otte 1992), the temporal structure of the call usually differs between sympatric species and appears to be an important parameter for identifying a potential mate of the same species (Bailey and Robinson 1971, Tauber and Pener 2000, Deily and Schul 2004, Bush and Schul 2006, Cole 2010, Hartbauer and Römer 2014.…”

Understanding the ecology and evolution of animal communication systems requires detailed data on signal structure and variation across species. Here, we describe the male acoustic signals of 50 species of Neotropical katydids (Orthoptera: Tettigoniidae) from Panama, with the goal of providing data and recordings for future research on katydid communication, evolution, ecology, and conservation. Male katydids were recorded individually using an ultrasound-sensitive microphone and high-sampling rate data acquisition board to capture both audible and ultrasonic components of calls. Calls varied enormously in duration, temporal patterning, peak frequency, and bandwidth both across and within subfamilies. We confirm previous studies showing that katydid species within the subfamily Pseudophyllinae produced short calls (<250 ms) at long intervals and we confirm that this is true for species in the subfamily Phaneropterinae as well. Species in the Conocephalinae, on the other hand, typically produced highly repetitive calls over longer periods of time. However, there were exceptions to this pattern, with a few species in the Conocephalinae producing very short calls at long intervals, and some species in the Phaneropterinae producing relatively long calls (1–6 s) or calling frequently. Our results also confirm previous studies showing a relationship between katydid size and the peak frequency of the call, with smaller katydids producing higher frequency calls, but the slope of this relationship differed with subfamily. We discuss the value of documenting the diversity in katydid calls for both basic studies on the ecology, evolution, and behavior of these species as well as the potential conservation benefits for bioacoustics monitoring programs.
