Acoustic and vibrational signaling in true katydid Nesoecia nigrispina: three means of sound production in one species.

ABSTRACT: The males of Mexican katydids Nesoecia nigrispina (Stal, 1873) produce calling songs and protest sounds using the typical stridulatory apparatus, situated, as in most of the other Ensifera, at the bases of the tegmina. It includes a stridulatory file on the upper tegmen and a plectrum on the lower one. The calling sounds, which are of two types (fast and slow), are two-syllabic series, with a repetition rate fluctuate within 3-4.5 s^-1 (fast) and 1.2-2 s^-1 (slow). After tactile stimulation, males produce protest signals in the form of short trills of uniform syllable duration. The syllable repetition rate is higher than that of the calling sounds: 7.7 s^-1. The frequency spectra of these signals have maxima in the band of 14-15 kHz. However, in additio
