GermanyA study published in PNAS reveals that bees exhibit distinct facial expressions when reacting to different food types, suggesting they may experience pleasure or displeasure. Researchers observed that bees stick out their tongues when encountering sweet substances like sugar, while shaking their heads and wiping their mouths occur when tasting salty or bitter liquids. These behaviors were captured using high-speed cameras and analyzed by an international team of scientists. The findings suggest that bees might have emotional-like responses, challenging previous assumptions about insect cognition. Dr. Andrew Barron, a neuroscientist involved in the research, argues these expressions provide insight into the internal states of animals. The study also notes that bee behavior varies depending on environmental factors such as temperature and satiation levels.
