Our existing research shows that honeybees and wasps can learn to recognise human faces. Other evidence – from a US research group – shows that paper wasps (Polistes fuscatus) can very reliably learn the faces of other paper wasps, and appear to have evolved specialised brain mechanisms for wasp face processing.

Can wasps smell fear?

Of course, those pheromones are also different, but bees can detect those as well. Rather than detecting fear, bees smell pheromones which alert them regarding an impending danger. They do not directly detect fear.
