Honey bees communicate distance via non-linear waggle duration functions

Area of Science:

• Animal Behavior
• Insect Communication
• Sensory Ecology

Background:

• Honey bees (genus *Apis*) use the waggle dance to convey resource location to nestmates.
• The relationship between waggle dance duration and flight distance has been debated, with older studies suggesting non-linearity and recent studies proposing linearity.

Purpose of the Study:

• To investigate the precise distance-duration relationship in honey bee waggle dances.
• To determine if honey bees process flight distance linearly or non-linearly.

Main Methods:

• Honey bees (*A. mellifera carnica*) were trained to feeders at distances from 0.1 to 1.7 km.
• Waggle and return phase durations of their dances were measured from video recordings.

Main Results:

• The waggle duration-distance relationship was better explained by a non-linear model with a decreasing slope than a linear model.
• A two-segment linear model with a break-point at 1 km also effectively described the waggle duration-distance relationship.
• The return phase duration-distance relationship was adequately described by a linear model.

Conclusions:

• Honey bees appear to process flight distance differently based on a threshold distance (around 1 km).
• These findings can refine the estimation of honey bee foraging distances by decoding waggle dances.
• Further research is needed to understand the evolutionary and physiological basis of this distance processing.
