Myth #3: They can see me coming…
True: Why yes, they can. Cockroaches can see humans, and that is why they tend to run in fear when we are in their line of sight. The eye of the cockroach is like a compound lens, made of over 2,000 mini lenses that are photoreceptors and allow them to see in complete darkness.
Are ants smart?
Individual ants have tiny brains but together the many ants of a colony can exhibit remarkable ‘intelligence’. Ants exhibit complex and apparently intelligent behaviour; they can navigate over long distances, find food and communicate, avoid predators, care for their young, etc.
