We have a lot to thank bees for, so maybe we should let them share our lattes.
It turns out that bees like caffeine, and that ingesting it actually boosts their memories. But where can they get it? They’re attracted to citrus flowers because they have caffeine-laced nectar, which hooks them the same way coffee hooks human imbibers.
The New York Times quotes brain specialist Geraldine Wright as saying, "The plant is using this as a drug to change a pollinator’s behavior for its own benefit." In other words, if the bees remember where those flowers are, they’ll return again and again to pollinate them.
