My Panesthia angustipennis angustipennis males are very noisy!
Once in a while one of them comes to the surface and starts making noise by hammerings with its abdomen on a piece of wood. The wood and the enclosure kind of resonates and enhances the noise.
I manages to make an audio recording with my audio recorder (see attachement). There is a lot of bass to hear (it's a decent recorder), and it gives a good idea what I have to endure here
I', pretty sure this is a way to attract females.
My question: has anyone observed a similar thing?
