In brief
Scientists at Macquarie University, together with Southern Medical University, discovered that honeybees display behaviours remarkably similar to mammalian emotions. By observing changes in activity after rewarding or aversive stimuli, researchers argue that bees possess an internal experience, reshaping how we view insect cognition. The findings open new avenues for understanding animal consciousness and could influence pollination strategies worldwide.
In a first‑of‑its‑kind project, researchers from Macquarie University in Australia and Southern Medical University in China recorded behaviour that mirrors emotional responses in mammals. By testing how worker bees reacted after tasks that were either rewarding or aversive, the team noticed clear changes in activity patterns that mirror the win–loss dynamics seen in mammals such as mice or rats.
The experiments included rewarding a bee with a treat after a task and withholding a reward to create an aversive condition. The bees were less active during the aversive periods, while their mobilisation increased when they expected a reward, a pattern that mirrors the dopamine‑mediated changes seen in vertebrate studies.
Although bees do not have brains as large as mammals, the study suggests that the neural architecture of insects is sufficiently complex to support a subjective, emotional component of perception. This new data challenges the prevailing view that insect behaviour is an automatic, stimulus‑driven process, and hints at a richer, more nuanced “inner life.”
