Hi daucle

Sorry, we can't say anything based only on this spectrogram. Do you have a sound recording?

Hi daucle

On the recording, I hear the typical song of Eupholidoptera. If the recording originates from Northern Italy, the specific species depends on the exact location: in the northwest, it is Eupholidoptera chabrieri, while in the northeast, it is Eupholidoptera schmidti.
