Collecting pollen can be as exhausting for bees as flight take-off, study shows

‘Floral buzzing’, the vibrations bees use to shake pollen loose from flowers, takes more energy than previously thought
Bees use as much energy collecting pollen through “floral buzzing” as they do taking off in flight, a study shows.
Scientists have found the vibrations bumblebees use to shake pollen loose from flowers are among the most exhausting behaviours they perform, forcing bees to “carefully choose” which flowers are worth visiting.
