    ABSTRACT
    In recent years, several species of Orthoptera were field recorded by the authors by using a low cost USB microphone with a sampling frequency up to 250 kHz. Here for the first time we propose a comprehensive review of the audio samples obtained, including envelopes, spectrograms and frequency analyses, to reveal their extension into the ultrasonic domain. Our research both extends previous similar efforts, such as the paper by Heller (1988) and covers for the first time several species for which ultrasound recordings are not reported in scientific literature.
