Scientists discovered that honeybees trained with sugar water can differentiate numbers and instinctively order them from left to right. Perhaps tellingly, the study took place during the pandemic, when many of us worked from home. We’re sure the researcher’s families appreciated them getting out of the house, even if it was to train bees and see if they can count in the backyard. The setup included a wooden wine box, pictured below. And because the lead author of the study is in France, the paper even mentions it’s from Chateaux Fontarney, in case that’s relevant.

The scientists tested whether bees have a concept of a mental number line, which is the instinct and ability to put numbers in increasing order. They found that bees trained on specific numbers preferred higher numbers when they were to the right and lower numbers on the left. The team published their researchOpens in a new tab in the peer-reviewed journal Proceedings of the National Academy of Sciences. We saw it thanks to ScienceNewsOpens in a new tab.
Scientists have previously found that bees can count and understand the concept of zero. Other animals, like crows and primates, share these abilitiesOpens in a new tab. Most humans have a mental number line that goes left to right as well, though scientists are still studying the cultural effects involved. After all, at least a dozen languages flow right to left.

Bees are remarkable animals. Hives can survive weeks buried in volcanic ashOpens in a new tab. Thousands can wave their bodies in unisonOpens in a new tab to ward off predators. If you prefer honeybee pop culture to honeybee science, it’s never a bad time to watch Bee Movie. And don’t forget that Rowan Atkinson recently starred in the Netflix show Man Vs.
