| Povzetek: | Many insects, including bushcrickets, use acoustic communication for mate finding and mate choice. These signals often produce simultaneous substrate vibrations, potentially aiding localization. However, independently produced vibratory signals are rarely documented in Orthoptera, despite their potential to enhance close-range communication. In the duetting bushcricket Ancistrura nigrovittata, acoustic communication has been extensively studied. We investigated whether any previously overlooked vibratory signals occur during close-range interactions in this species, and characterised their properties and interplay with acoustic signals. Combining laser vibrometry, audio and video recordings, we revealed soundless abdominal tremulation signals in both sexes during partner search and pair formation. Although subtle, these movements produce substrate vibration with amplitudes exceeding those induced by acoustic signalling (stridulation) by an order of magnitude. In both sexes, tremulation and acoustic signals can occur simultaneously or separately, demonstrating independent production mechanisms. Females combine song with tremulation during longdistance calling, use primarily tremulation after a male enters a plant, and typically cease signalling upon being found. Males add tremulation to the song after entering a plant and use it as the primary signal after partner contact. In both sexes, tremulation comprises mostly grouped pulses, emitted at a rate of about 2.5 Hz. Male tremulation exhibits a lower pulse number per train, higher dominant frequencies and amplitudes than female tremulation, and is typically accompanied by a short acoustic tick at the beginning of each pulse. Our findings reveal a previously unknown complexity of vibroacoustic communication in A. nigrovittata. |
