Rise in Aggressive Bee Behavior in Southern California Communities.

Some Southern California communities are experiencing unusual aggressive bee behavior, with Pasadena hiring a bee expert to deal with vicious swarms and Encino still reeling from a recent attack on a volunteer police officer. Bee experts say the behavior is unusual for the species, who do not attack humans unprovoked. The aggressive bees in Encino must have been "disturbed," according to one expert. Pasadena has instituted a measure to relocate aggressive bees in light of a recent attack there.
