To elucidate the role of stridulatory sound in the burying beetle Nicrophorus quadripunctatus (Coleoptera: Silphidae), we investigated the type and temporal pattern of stridulatory sounds during reproduction. As a result, two types of stridulatory sounds, single and continuously repeated ones, were detected. The single sound was frequently emitted in the early stages of reproduction when hatchlings were not yet present. So, this sound may be used for parental communications. In contrast, frequencies of the continuous sound increased at the time when hatchlings appeared, suggesting that the sound is used for communication between parents and larvae.
