Sexual dimorphism and the impact of aging on ball rolling-associated locomotor behavior in Drosophila.

Insects exhibit a remarkable ability to interact with inanimate objects to facilitate essential behaviors such as foraging, reproduction, shelter building, and defense. In this study, we assessed whether Drosophila interacted with inanimate objects when they were suspended on their wings and provided with a thermocol ball (foam ball). Drosophila indeed exhibited ball rolling behavior.
