Members of the Agonum, including A. cupreum, have been referenced in studies using clay models in turfgrass . A 2021 study by Khan and Joseph used generic Agonum sp. -shaped clay models to assess activity patterns, demonstrating that beetle-shaped models receive fewer attack marks than -shaped models.
