How do bees communicate the location of food sources?

Introduction

Bees have developed sophisticated methods to communicate the location of food sources to their nestmates. This communication is crucial for the efficiency and survival of the colony. The primary method of communication among honeybees is the waggle dance, but other mechanisms such as olfaction and visual cues also play significant roles.

Key Insights

Waggle Dance for Direction and Distance:
- Honeybees use the waggle dance to communicate the direction and distance of food sources to their nestmates. The angle of the dance relative to the vertical indicates the direction, while the duration of the waggle phase indicates the distance .
- The waggle dance is a multicomponent signal, where location information serves as backup if direct environmental cues are unavailable or unreliable.
Olfaction and Scent Cues:
- Bees can locate food sources using olfactory cues. The scent of the food source accumulates in the hive, enhancing recruitment efficiency over time.
- Scent-triggered navigation allows bees to revisit food sources by associating specific scents with particular locations, even if the food is no longer present.
Visual Cues and Landmarks:
- Bees use visual cues, such as the location and color of flowers, to navigate to food sources. They store a two-dimensional snapshot of their surroundings to guide their return.
- Landmarks play a crucial role in guiding bees back to food sources, but they do not construct a cartesian map of the area.
Path Integration:
- Honeybees use path integration, which involves integrating distances and directions flown, rather than relying on a cognitive map of their surroundings.
Stingless Bees Communication:
- Some stingless bees, like Plebeia droryana, can communicate the direction but not the distance to food sources. They do not use chemical or visual cues from nestmates for this purpose.
Levy Flight Search Strategy:
- Honeybees employ a Levy flight search strategy and odour-mediated anemotaxis to locate food sources. This strategy is optimal for finding patchily distributed resources.

Conclusion

Bees utilize a combination of the waggle dance, olfactory cues, visual landmarks, and path integration to communicate and navigate to food sources. The waggle dance is the primary method for conveying direction and distance, while olfactory and visual cues provide additional navigational aids. Stingless bees, although less studied, also exhibit unique communication methods. These multifaceted strategies ensure efficient foraging and resource allocation within the colony.

Communication of Direction by the Honey Bee

The honey bee communicates directional information through its dances, enabling recruits to locate food sources more effectively than food sources at an equal distance in the opposite direction.

Honey Bee Recruitment to Food Sources: Olfaction or Language?

Honey bees locate food sources by olfaction, not distance and direction information in the recruitment dance, with recruitment efficiency increasing as odor accumulates in the hive.

Foragers of the stingless bee Plebeia droryana inform nestmates about the direction, but not the distance to food sources

Plebeia droryana stingless bees can guide nestmates in the direction of food sources, but not the distance, but the exact mechanism for this communication remains unclear.

Scent-triggered navigation in honeybees

Honeybees can navigate to distant food sources by recalling familiar scents, even when the food source is no longer present.

Dancing honey bees indicate the location of food sources using path integration rather than cognitive maps

Dancing honey bees indicate the location of food sources using path integration rather than cognitive maps, rejecting the cognitive map concept.

How honey bees use landmarks to guide their return to a food source

Honey bees use landmarks to guide their return to a food source, but instead store a two-dimensional snapshot of their surroundings, guiding their movements to reduce discrepancies between the snapshot and their current retinal image.

Honeybees use a Lévy flight search strategy and odour-mediated anemotaxis to relocate food sources

Honeybees use an optimal Lévy flight searching strategy and odour-mediated anemotaxis to locate new food sources, focusing on scents upwind and ignoring unscented or unrewarding targets.

How Bees Navigate

Bees communicate food locations using a dance, which is oriented to the polarization of the sky, to guide their movements towards food sources.

The honeybee waggle dance: can we follow the steps?

The honeybee waggle dance is a multicomponent signal, with location information being a backup component for when environmental information on food sources is unavailable or of poor quality.

Do honeybees use the directional information in round dances to find nearby food sources?

Honeybees can use the directional information in round dances to find nearby food sources, supporting the view that round dances are waggle dances indicating nearby food sources.
