Stridulation in <i>Nicrophorus investigator</i> as a Possible Means of Cooperation during Carcass Sequestration
Abstract
Burying beetle stridulation has been observed and documented when caring for their young, as well as among agonistic beetles competing for carrion. Burying beetles in the genus Nicrophorus require a small carcass, typically 16-50 grams, in order to reproduce. Once located, the carcass is buried by the burying beetles, after which the beetles lay their eggs in the underground chamber and partake in biparental care. This study found that N. investigator pairs use stridulation during carcass sequestration when faced with an obstacle, but found no significant difference between the beetles’ use of stridulation and lack thereof in terms of their ability to move carrion.
