In a groundbreaking study published in the Proceedings of the National Academy of Sciences, researchers have shed light on the navigation methods of dung beetles, revealing that these insects primarily use celestial light patterns and alternative light sources to maintain a straight path while rolling dung balls.
For over 15 years, Marie Dacke, a scientist, has been studying the navigation methods of these fascinating creatures. Her latest research, conducted in two-foot-wide domes mimicking the beetles' natural habitat, has provided new insights into their sensory systems and navigation strategies.
Dung beetles navigate using various celestial cues, such as the sun during the day and the Milky Way at night. Remarkably, when the sun is at its highest point and thus useless for navigation, dung beetles follow the wind, demonstrating their ability to feel the wind rather than smell something in it.
Day-rolling species like Scarabaeus lamarcki look to the sun as their guiding star, while nocturnal species like Scarabaeus satyrus use the light of the Milky Way when the moon isn't available. Interestingly, Scarabaeus zambesianus uses the polarized light of the moon for navigation.
The study suggests that dung beetles are merging two different kinds of information - one mechanical (wind) and the other visual (sun or moon) - into a single brain region. The researchers plan to make recordings from the neurons inside the compass of the beetle to further understand this fascinating process.
The experiments involved an adjustable LED standing in for the sun and fans creating different speeds and directions of wind flow. Removing the club at the end of a dung beetle's antennae does not affect its ability to follow the wind when the sun is high, indicating that the beetles are feeling the wind rather than smelling something in it.
When celestial cues are unavailable, dung beetles can adapt by relying on light illusions, following reflections or artificial light as substitute navigational aids. This adaptability is a testament to the remarkable navigational abilities of these tiny insects.
Paul Graham, a researcher studying ant navigation, finds the study's findings clear and believes the dung beetle's rolling behavior is easy to interpret. The findings suggest that dung beetles can interpret two different kinds of signals and opt to use one or the other depending on the conditions around them.
Despite these advancements, plenty of mystery still remains about the perception of the world by dung beetles. The researchers plan to investigate how a dung beetle evaluates the information provided by either the wind or sun and how it determines which one to use.
This study not only deepens our understanding of these intriguing insects but also opens up possibilities for further research into animal navigation and perception.
