Insects use different signal modalities to communicate with their conspecifics. Substrate-borne vibrations are widely used among those communicating with mechanical signals. We studied the role of signal intensity for the mating behaviour in Scaphoideus titanus, a vibrational communicating leafhopper that is a vector of the lethal phytoplasma grapevine disease Flavescence dorée. As males called for the females and the intensity of the female replies was in the range between 0.0005 - 0.001 mm/s, males either walked around randomly and emitted long, irregular identification signals, or performed call-fly behaviour, by jumping off the plant after a female reply. As the male was approaching the female and the perceived intensity of the reply increased to more than 0.001 mm/s, a short location duet with more regular pulse latencies took place. Only when male and female were on the same leaf, courtship duets with regular male and female pulse emissions were recorded with intensities <0.01 mm/s. These results show that the rate of signal production and the perceived signal intensity are necessary parameters for species recognition or for location of the conspecific partner.
