Honeybees exhibit a range of behaviors that fascinate and often mystify beekeepers and entomologists alike. Among these is washboarding, a collective activity exhibited predominantly by young worker bees, particularly when nectar flows diminish. Unlike individual behaviors, washboarding manifests both inside and outside the hive, where bees engage in a rhythmic, rocking motion on the hive’s surface, a sight reminiscent of clothes being scrubbed on an old-fashioned washboard.
Spanning all variations of Apis mellifera, the species known as the Western honeybee, washboarding is a remarkable event where bees meticulously line up, their hind legs anchored while their front legs perform the repetitive, dance-like motion. Observers will often notice these bees also licking the hive’s surface, adding another layer of intrigue to the phenomenon.
Typically lasting from one day to two weeks, washboarding has fundamental clues pointing towards its occurrence such as the age of worker bees, time of day, and climactic conditions. Below is a comprehensive breakdown of washboarding behavior:
- Young worker bees aged between 15 to 25 days engage in washboarding, with the behavior peaking at this age range.
- The activity is generally observed from early in the morning till the early evening, with the intensity fluctuating depending on the time of day.
- Rough surfaces of the hive are preferred over smooth ones for this behavior.
- Both domesticated and wild honeybee colonies display washboarding behavior.
- There is no direct connection between washboarding and bearding, another well-known bee behavior.
- Washboarding often coincides with periods of nectar scarcity, prompting the need for beehive inspection.
Investigating the Purposes of Honeybee Washboarding
Though washboarding’s precise purpose remains a topic of debate, several compelling theories have emerged to explain why honeybees engage in this activity:
Pathogen Removal
Some beekeepers postulate that washboarding serves as a sanitation ritual to rid the hive entrance of pathogens. The meticulous nature of the behavior, focused on rough surfaces, suggests an effort to create an environment less conducive to harmful microorganisms.
Particle and Waste Clearance
This theory proposes that washboarding may help remove debris collected over the honey season. The correlation between foraging activity and washboarding timing lends support to this idea, as bees may be cleaning up after returning from their foraging expeditions.
Reinforcing Colony Scent
The repetitive application of scents at the hive entrance and interior could be another reason for washboarding. The worker bees spread pheromones that aid in guiding foragers back to the hive with precision.
Occupying Idle Bees
It is also believed that washboarding might occur when worker bees, with no immediate tasks, engage in this behavior as a form of ‘busy work’ outside the hive.
Genetic Factors
Another possibility is that washboarding tendencies may be inherited, as certain bee colonies exhibit the behavior more prominently, suggesting potential genetic roots.
Adaptation to Food Scarcity
Observers have noted an increase in washboarding during times of limited food sources. This could indicate that bees opt to conserve energy by engaging in activities close to the hive, waiting for the next nectar flow.
Practical Implications for Beekeepers
While washboarding remains somewhat enigmatic, it is essential for beekeepers to be observant and attentive to the hive’s needs when this behavior arises. A careful inspection may reveal underlying issues such as a need for food supplementation or other colony management adjustments.
Honeybee behavioral patterns like washboarding are not just captivating phenomena but carry implicit messages for those who manage hives. Understanding these signals can lead to more informed beekeeping practices that ensure the well-being and productivity of the hive.
By delving into the research and staying attuned to the nuances of bee behavior, beekeepers can better support their colonies, particularly during those times when external cues suggest potential distress or change within the hive environment. Whether it’s providing food supplements during a dearth or making modifications to the hive based on observed behaviors, a comprehensive approach to hive management can lead to thriving bee colonies.

Each of these areas provides further insight into the remarkable complexity of honeybee behavior and the art of bee colony management.
Lastly, it’s important to note that while we continue to uncover more about our industrious little friends, there’s always more to learn. Honeybees’ washboarding may be one of the many mysteries that keep the world of beekeeping an endlessly fascinating endeavor.
