Anti‐Predation and Size‐Dependent Gas Exchange Functions of Amazonian Architect Cicada Towers

Year: 2026
Type: article
Abstract: ABSTRACT Nymphs of several cicada species build clay towers before adult metamorphosis. However, tower function is poorly understood. Here, we show experimentally that towers of the Amazonian cicada Guyalna chlorogena reduce predation risk and display a size‐dependent growth response to gas exchange obstruction. These findings support them as adaptive extended phenotypes.
