Ringed Bush-cricket Grasshopper recording using Dodotronic Ultramic 384k

This Ringed Bush-cricket , Rhacocleis annulata, first report for Northern Italy

Here the recording of the grasshopper Ringed Bush-cricket, Rhacocleis annulata, first for Northern Italy, which produces a call that is difficult to hear without the aid of a bat detector.
The first ten phrases using a bat detector; the second ten phrases using a Zoom H1 and an AOM5024 PUI microphone.

Below a recording using an ultrasonic USB microphone Ultramic 384k by Dodotronic.

Seven prashes using USB microphone Ultramic 384k by Dodotronic, at different distances, set to mid gain.
Ultramic 384k recording distance: 0,5 meters – 2 meters – 8 meters


For comparison, I also made a recording using a Zoom H1 recorder and an external DIY stereo microphone system with 2x Primo EM172 capsules.
Despite having a decidedly higher self-noise than the EM172 capsule, the 384k has proved to be more suitable for recording high frequencies, as it was likely to be expected.

note: I didn’t cut the passage of the car to highlight the difference at low frequencies.

I wish to thank my friends Cesare Brizio e Filippo Maria Buzzetti for helping me in recognizing the species.
