NEW YORK — Talk about a caffeine buzz: A new study says honeybees get a shot of caffeine from certain flowers, and it perks up their memory.
That spurs them to return to the same type of plant, boosting its prospects for pollination and the future of the plant species.
Maybe it shouldn’t be a surprise that one of the flowers is the coffee plant. Its nectar offers about as much caffeine concentration as a cup of instant coffee, according to researchers.
The caffeine helps a bee remember that the flower’s scent promises a tasty payoff, the researchers said. So the bee will seek out those flowers, transferring their pollen.
