Bumblebees show surprising and highly adept teamwork skills

An intriguing new study reveals that bumblebees, known for their vital role as pollinators, possess an unexpected capacity for teamwork and cooperative problem-solving.

This research suggests that complex social behaviors may not be solely reliant on large brain size, as commonly assumed.

Unexpected bumblebees teamwork

Researchers at the University of Oulu in Finland got creative to understand how bumblebees cooperate. They designed two clever experiments:

  • Teams of two bumblebees were trained to push a small Lego block towards a center target to earn a sweet nectar treat. This required them to figure out that they both needed to push at the same time.
  • In a different setup, bumblebee pairs faced a transparent tunnel with a door at the end. To reach the nectar reward, they had to figure out how to simultaneously touch the door to make it open.

The bumblebees didn’t just learn these strange new tasks; they shocked the researchers. When one bumblebee in a pair was delayed, its partner often waited before starting the task. Even more, they were more likely to start pushing only when their partner joined in.

In the tunnel challenge, some bees turned around when their partners were delayed, even before reaching the door. Interestingly, when they saw their teammate heading the right way, they turned around again.

These actions suggest that bumblebees aren’t just blindly going through the motions. They might be actively adjusting what they do based on what their teammate is (or isn’t) doing!

“Our findings show for the first time that bumblebees can learn to solve novel cooperative tasks outside the hive. But the coolest part of this work is that it clearly demonstrates that bumblebee cooperation is socially influenced, and not just driven by individual efforts,” states Dr. Olli Loukola, the study’s lead researcher.

Bumblebees evidence of intentional teamwork

Bumblebees who were trained collaboratively demonstrated behaviors hinting at intentional cooperation. When a partner was delayed, they were more likely to wait before initiating the task and adjusted their actions based on their partner’s movements. This raises the intriguing question of whether they actively coordinate their efforts to achieve a shared goal.

For a long time, scientists believed that complex social behaviors, like teamwork and understanding how to work together, required a big ol’ brain.

Humans, dolphins, elephants – these were the poster children for collaboration. But bumblebees? Their brains are incredibly tiny compared to ours!

Small brains can accomplish amazing things

This research flips that idea on its head. It shows that even a creature with a miniature brain can work with others towards a common goal. This makes us question what’s really needed for cooperation to develop.

If insects as seemingly simple as bumblebees possess teamwork skills, it changes how we think about the origins of cooperation.

Maybe the ability to work together isn’t something that suddenly appeared in big-brained mammals. Instead, it could have deeper evolutionary roots, starting with much earlier, simpler life forms.

“This research can contribute to a broader understanding of animal behavior and evolution. It may also inspire new research on the evolution of social intelligence and cooperation in different animal species,” notes Dr. Loukola.

Future research and broader impacts

While it remains to be fully determined whether bumblebees grasp the full implications of their cooperative actions, this study offers strong evidence for their collaborative capabilities.

“Whether bumblebees truly understand the role of their partner will require further research with more detailed monitoring of their behavior during cooperation,” Dr. Loukola indicates.

Beyond its purely scientific value, this work on bumblebee cooperation carries significant potential applications in technology and robotics.

Understanding the collaborative strategies of these insects could provide inspiration for designing robots that work together effectively, adapting to changing circumstances.

These principles could help shape the next generation of robots used in fields like search-and-rescue or complex manufacturing tasks.

Additionally, this research spotlights the unexpected complexity of insects, fostering a greater appreciation for their intelligence and social behaviors.

This newfound understanding could bolster conservation efforts, emphasizing the importance of protecting bumblebees and the delicate ecosystems they support.

The study is published in the journal in Proceedings of the Royal Society B.
