Scientists have found a relationship between the brain size of bees and their diet

Panurgus Banksianus is a large hairy bee that lives alone, burrowing in sandy meadows throughout Europe. Prefers

eat yellow-flowered representatives of the Aster family. A large shaggy bee has a very large brain. And a new study explains how it relates to her diet.

Scientists note that compared to the brainIn mammals, the brain of insects has received little attention from scientists, and not much is known about it. In this new study, the researchers sought to partially fill that gap by studying the brains of 395 bees, the brains of 93 species found in Spain, the United States and the Netherlands. Their job was to extract the brain from each specimen and compare its size with other bees, then looking for ways to explain the differences.

Researchers have found some patterns. For example, the length of a bee's generation can correlate with the size of the bee's brain. Scientists point out that this is not surprising, because the same can be said for birds and many other animals. What really surprised them was the link between diet and brain size. Bees with less dietary diversity had larger brains than bees with a varied diet. In most animals, the opposite is true. The researchers speculate that this could be due to the fact that it would not take a lot of brain energy to eat a flower in the field - identifying specific flowers would require much more processing.

The researchers also compared brain size tosocial behavior and found little difference between bees. The brains of single bees were no larger or smaller than those of bees living in complex hives. The researchers note that this was also expected. Unlike most animals, the social behavior of bees is mostly fixed. Bees communicate only in the hive, where they carry out their duties, for example, tending the cubs or collecting pollen.

Researchers have been unable to determine if there were beeswith a larger brain are smarter than bees with a smaller brain; the differences in size seem to be mainly related to the activities that the bees engage in during their life cycle.
