In an artificial setting, Farina and Nuñez (1991) recorded durations of trophallactic exchanges that ranged from roughly 5-13 sec. In an observation hive, Farina and Wainselboim (2001) recorded trophallactic exchanges between foragers and receiver bees lasting roughly 23-26 sec.
Both the size of the nectar load a forager takes and the rate at which she unloads it to a receiver bee respond positively to the reward level of the nectar and proportionally to each other; so, unloading time is held fairly constant with respect to reward level (Farina and Wainselboim 2001).
