Wasps, bees, bumblebees, earwigs: though their brains are tiny, they are highly intelligent. They can recognise faces, navigate perfectly and even solve tricky mental tasks. The latest research shows that we have long underestimated insects. Bumblebees, for example, even pass behavioural tests that the smart crows can manage. Wasps even have the ability to reason, i.e. to think logically. Our image of insects has changed significantly. But what does that mean for our relationship with them? And if they are so intelligent, do they also have individual personalities or even feelings? Delve into the realm of the smart insects and be amazed.
