The male calls (vibrational signals transmitted through the plant) were recorded in Nahal Shitta, Israel, using the pickup cartridge method (Tishechkin 2022), with a EQ-7545R Preamplifier. Oscillograms and a spectrogram of the male call were prepared using the ‘spectro’ function implemented in the R package Seewave (Sueur et al. 2008). RX 9 Audio Editor v. 9.3.0.1435 was used to reduce background noise; its screen recording via Free Cam v. 8 was used to create the dynamic oscillogram and spectrogram. Terminology of vocal calls follows Bluemel et al. (2014) and Tishechkin (2021).
