Bees can learn the difference between European and Australian Indigenous art styles in a single afternoon

We’ve known for a while that honey bees are smart cookies. They have excellent navigation skills, they communicate symbolically through dance, and they’re the only insects that have been shown to learn abstract concepts.

Honey bees might also add the title of art connoisseur to their box of tricks. In part one of ABC Catalyst’s The Great Australian Bee Challenge, we see honey bees learning to tell the difference between European and Australian Indigenous art in just one afternoon.

Does this mean honey bees are more cultured than we are?

Perhaps not, but the experiment certainly shows just how quickly honey bees can learn to process very complex information.

How the experiment worked

Bees were shown four different paintings by the French impressionist artist Claude Monet, and four paintings

Bees are quick to learn

This kind of work does not show bees have a sense of artistic style, but it does show how good they are at learning and classifying visual information.

Different artists – be they Marawili, Monet or Picasso – tend to prefer different forms of composition and structure, different tones and different pallets in their art. We describe this as their distinctive style. These styles are recognisable to us, even if most of us would be hard pressed to describe exactly what makes a Marawili different from a Monet.

When the honey bees were trained on the paintings, every Monet they visited was a bitter experience, while every Marawili was sweet. This motivated the bees to learn whatever differences best distinguished the set of Marawili paintings from the set of Monets.

Bee colour vision is excellent, if different from ours. Bees can see ultraviolet wavelengths of light, but not red. Bees can pick up structure and edges in paintings by zipping quickly back and forth in front of them to detect abrupt changes in the brightness of an image.

In our experiment, bees could detect enough differences between the Marawili and Monet paintings to learn to tell them apart. The bees were not memorising the paintings; instead they were learning whatever information best distinguished a Monet from a Marawili. They could then maximise their collection of sugar, and avoid any bitter surprises.

Learning the visual differences between one set of Monet and Marawili paintings was enough for the bees to correctly choose between Monet and Marawili paintings they had never seen before.

Similarities between art and flowers

This experiment taps into a highly evolved honey bee skill. Bees did not evolve to differentiate between artists, but their survival depends on learning to tell which flowers are most likely to offer the best pollen and nectar they need to feed their hive.

Because of this, bees have evolved the ability to very quickly process complex and subtle visual information. These learning skills are on display when bees forage on flowers. Bees quickly learn to pick up on the subtlest distinction between fresh and older flowers, be it colour, odour or texture, which can betray the blooms that are most likely to contain a drop of nectar.

A bee lands on a daisy flower.

Honey bees break any stereotypes we may have that insects are dumb, instinct-driven animals. They have an intelligence that is very different from ours, but one that has evolved to be fit for the task of a bee doing what a bee has to do.

It is hard not to admire such clever and discriminating creatures.
