    Ultrasound recordings of some Orthoptera from Sardinia (Italy)

    ABSTRACT
    During August 2013, Ultramic 250 by Dodotronic was field-tested for application in Orthopteran acoustic biodiversity studies. The songs of four species were recorded: Uromenus brevicollis insularis Chopard, 1924, Rhacocleis baccettii Galvagni, 1976, Svercus palmetorum palmetorum (Krauss, 1902) and Oecanthus dulcisonans Gorochov, 1993. The recording campaign proved the viability of Ultramic 250 for field use and provided the opportunity to assess the presence in South-Western Sardinia of two less documented species, Svercus palmetorum palmetorum (Krauss, 1902) and Oecanthus dulcisonans Gorochov, 1993.

    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.
