Bumblebees
Bees have been dubbed the “world’s smartest insect” for good reason. They can solve puzzles and have exceptional navigational skills. One experiment found bees work out the optimal route to a flower with repeated visits, significantly reducing the time it takes for them to get there. Another experiment found that bees create mental images of objects like humans do and can transmit recognition of objects across their senses. For example, they can identify objects in the dark by touch if they’ve seen them before.
