Those who go slow choose better
Even among the bumblebees there are accurate individuals and others more hurried.

Bumblebees, large insects related to bees, choose different strategies to collect nectar from flowers.

Bumblebees, insects related to bees, know how to "ponder" situations and spend more time solving problems when making mistakes can mean a disadvantage for them. Just like we do too. This extraordinary ability was demonstrated by an international team of German, British and Australian researchers, who tested the reactions of Bombus terrestris specimens while feeding in a virtual flower field.
Sweet blue flowers. Scholars have created blue flowers enriched with a drop of sucrose. In other darker blue flowers, only water was put. The bumblebees, flying among the flowers, have adopted two strategies: some quickly flew from one flower to another, with a high percentage of error; others were slower, but they chose better. When in dark blue flowers the water was replaced with an unpleasant substance to bumblebees, those that had previously proved to be accurate in the choice became even more so. Bumblebees are the first example of insects capable of modulating the speed of their choices to obtain greater accuracy.
