Bees get a buzz from the nectar of certain flowers

 

UNDATED (AP) -- Talk about a caffeine buzz: A new study says bees get a shot of caffeine from the nectar of certain flowers, and it perks up their memory.
 
One of those flowers is the coffee plant, which offers about as much caffeine concentration as a cup of instant coffee. Some citrus plants serve caffeine too, although in lower concentrations. Researchers found it in the nectar of orange and grapefruit blossoms.

The work was reported online Thursday in the journal Science
