In late April 2022, while listening to audio files from an unsupervised bioacoustic assessment of the shearwater populations (Aves, Procellariiformes) on the coast of Pantelleria island (Sicily, Italy), a cricket song of unknown attribution was heard. The first bioacoustic analyses, including FFT-based spectrograms and sound pressure envelopes, con...

In recent years, several species of Orthopterans were fi eld-recorded by authors 1 and 3 thanks to an innovative, low cost USB microphone with a sampling frequency of 250 kHz. In August 2019, during an acoustic exploration for Orthopterans, author 1 intercepted sounds from a burrow in the soil, from which a Sphecid wasp – here tentatively determine...

The burrowing buzz of Sphex sp. extends to the inaudible range. In recent years, several species of Orthopterans were fi eld-recorded by authors 1 and 3 thanks to an innovative, low cost USB microphone with a sampling frequency of 250 kHz. In August 2019, during an acoustic exploration for Orthopterans, author 1 intercepted sounds from a burrow in...

Since field research requires a lot of effort, time, economic and resource investment, it necessitates fact-based tools for a sound preliminary evaluation of the actual possibility to achieve its objective. Such a tool, the Encounter Predictability Scorecard (EPS), is here described for the first time. The rediscovery of the endemic Orthopteran Uro...

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...

A practical, manual workflow to obtain a quick, exhaustive digital photographic coverage of all the items in a collection is described, together with the technical details of the equipment used. Even though no radical technological improvement over similar techniques is adopted, the unique combination of a professional video camera, dimmable indire...

Recent findings of the Sardinian endemic Bushcricket Uromenus annae (Targioni Tozzetti, 1881) allowed the authors to retrace the nomenclatorial history of the species. The rearing of living specimens resulted in the recording of the male song, previously unknown. Since the Neotype previously established by Fontana & Buzzetti (2001) is lost, a new N...

During August 2013, a low-cost ultrasonic USB microphone (Ultramic 250 by Dodotronic), was field-tested for its first application ever in Cicadomorphan bioacoustics studies. Two different species were recorded in the ultrasonic domain, with 250 kHz sampling frequency, one of them also with 96kHz audio recordings for comparison purposes. Ultramic 25...

During August 2013, Ultramic 250 by Dodotronic was field-tested for application in Or-thopteran acoustic biodiversity studies. The songs of four species were recorded: Uromenus brevicollis insularis Chopard, 1924, Rhacocleis baccettii Galvagni, 1976, Svercus palmeto-rum palmetorum (Krauss, 1902) and Oecanthus dulcisonans Gorochov, 1993. The recordi...
