Does cockroach have emotion (fear, anger, happy)?
Timothy, Emotion is not usually associated with insect or cockroach behavior. The cold and unmoving surfaces of the insect exoskeleton do not allow for movement of surface muscles and skin that one can interpret as a smile or other facial emotion. Insects react to environmental cues with reflexes that we usually do not interpret as emotion. Have you ever seen the waggle communication of the worker honeybee? It is used to communicate the direction and richness of a nectar source. That is interpreted by insect behaviorists to be a reflex behavioral response released by finding the nectar source. The public might interpret it as an indication that the worker is happy at finding the sweet nectar. Go figure? Is there any evidence that the bee is happy? What would that evidence be?
