Dr. Lars Chittka is a Professor of Sensory and Behavioral Ecology and the founder of the Research Center for Psychology at Queen Mary University of London. He directs the Bee Sensory and Behavioral Ecology Lab, and is the author of The Mind of a Bee. In this episode, we discuss the results of decades of research on intelligence in bees and other insects. This includes findings of numerical and spatial cognition, memory, perception, and personality. Lars describes differences and similarities between bumblebees, wasps, and honeybees, why honeybees produce so much honey and die after stinging and mating, and more. We also discuss the evidence for bees having emotions, feeling, and consciousness, and efforts for the preservation and ethical handling of bees.
