Abstract The results of the bioacoustic study carried out on larvae of Phileurus didymus (L.) which emit a sound by compression and release of air (forced air) when they are disturbed are presented. The average duration and frequency of the acoustic patterns obtained, along with illustrations are presented. The biological functions of these sounds are discussed, as well as the possible applications that techniques used and proposed may have in the behavioral study of the larvae of other Scarabaeoidea. The recording data of the sounds obtained in this work are shared.
