This article shows just how intelligent insects can bee
When bumblebees were made to observe other bumble bees move a ball into a goal in exchange for a food reward, they quickly learned to imitate this behavior. This would already be impressive, but researchers also found that the bees were doing more than just copying behavior. Balls of varying distance from the goal were placed in the testing area, and the first group of bees were made to pull the farthest balls into the goal. The test bees that observed this would still pull the closest balls into the goal. Rather than blindly copying their predecessors' behavior for a reward, the bees were able to identify the specific objective that earned the reward, and identify the most efficient solution for achieving that objective.
