The Biology Behind Festooning
Wax Production and Secretion: Wax is produced by specialized glands located on the underside of a worker bee’s abdomen. These glands secrete tiny wax scales when the bee’s body temperature reaches approximately 91-97°F (33-36°C). Festooning helps achieve this temperature by clustering together, which increases the hive’s ambient temperature.
Role of Pheromones: Bees rely on chemical communication, and festooning helps enhance the distribution of pheromones throughout the hive. Queen mandibular pheromone (QMP), for example, influences the behavior of the workers and encourages cooperative building activities. The close contact during festooning aids in the spread of these important chemicals, ensuring synchronized action among the bees.
Muscle Function and Energy Use: The act of festooning involves significant muscle use. Bees will often clasp each other’s legs and hold these positions for extended periods. This muscular engagement requires energy, which they get from consuming stored honey or nectar. Their metabolic rate increases to generate the warmth needed for wax secretion.
The Role of Festooning in Hive Construction
Comb Geometry: The hexagonal cells of honeycomb are not just aesthetically pleasing but are a marvel of engineering, maximizing space and strength while minimizing the use of wax. Bees in a festooning chain act like surveyors, allowing them to measure and space out the comb accurately. This communal measurement ensures that combs are parallel, evenly spaced, and structurally sound.
Adaptive Strategies: When bees are constructing combs in natural settings, such as in the wild within tree hollows, festooning becomes even more critical. It helps them adapt their construction to the irregular surfaces and shapes of their surroundings. The formation acts as a bridge that allows bees to start comb construction from multiple points and join the comb seamlessly.
Why Do Bees Choose Specific Locations to Festoon?
Temperature and Humidity: The specific areas where bees choose to festoon are often warmer and more humid, ideal conditions for softening and working with wax. Bees are highly attuned to these microclimatic conditions and strategically position themselves in areas that support efficient comb construction.
Structural Anchoring: Bees choose to festoon in places where they need additional support to build out the comb. This behavior helps them anchor the comb securely to the hive’s top bars or natural structures, preventing it from detaching due to its weight or movement within the hive.
Observing Festooning in Your Hive
When to Expect Festooning: Beekeepers are most likely to see festooning when a hive is building or repairing comb, such as during periods of rapid colony expansion in spring or after new frames with foundation are introduced. It can also occur when the colony is moved to a larger space and needs to extend the comb to store honey or raise more brood.
Interpreting Festooning Behavior: Frequent festooning is often an indicator of hive health and strong colony motivation. Conversely, a lack of festooning during times when comb building is expected may suggest a shortage of resources such as nectar, pollen, or a weak population. This could also point to issues such as wax moth infestation or environmental stressors like pesticides that disrupt normal bee behavior.
Practical Applications for Beekeepers
Supporting Comb Building: To encourage festooning and comb construction, beekeepers can:
• Provide Ample Resources: Ensure that bees have access to sufficient nectar and pollen. If natural sources are scarce, supplemental feeding with sugar syrup can stimulate wax production.
• Maintain Optimal Conditions: Position hives where they receive morning sun to warm up early in the day, and ensure adequate ventilation for humidity control.
• Use Proper Foundation: Bees tend to festoon more readily when they have a foundation to build on. Using foundation frames or starter strips can make the process more efficient for them.
Advanced Insights and Research
The Role of Genetics: Different strains of bees may exhibit varying tendencies to festoon. For instance, Italian bees are known for their active comb building and might show more festooning behavior compared to other strains like Carniolans or Caucasians. Researchers continue to study these differences to better understand the genetic factors influencing hive construction.
The Science of Structural Efficiency: Engineers and architects have taken inspiration from the principles of festooning and honeycomb construction for designing lightweight, strong structures. The way bees distribute weight and create suspended bridges is being applied in the development of innovative building techniques and materials.
Recent Studies: Current research is exploring how environmental changes, such as climate change and habitat loss, impact festooning and hive construction. Studies indicate that stressors affecting bee health, such as varroa mites or exposure to pesticides, may disrupt normal festooning patterns and wax production.
The Connection to Ecosystem Services
Beyond the hive, festooning plays a role in the broader ecological context. The combs built with the help of festooning are essential for honey storage and brood rearing, enabling the colony to thrive. This, in turn, supports the bees’ role as pollinators, contributing to biodiversity and the health of ecosystems. The efficient production of combs ensures that the colony can store sufficient honey and pollen, sustaining them through challenging seasons and enabling them to pollinate plants throughout the year.
Understanding festooning helps beekeepers appreciate the complex behaviors that underlie the productivity of their hives and underscores the bees’ ability to work collectively for the success of the colony.
