Bee Dancing

Honey bees do a waggle dance to direct other bees to sources of nectar (花蜜). But dancing bees like this one can be halted by a head butt from another bee. Now researches have found that this head butt is actually a warning signal. A feeding station was set up in the lab to mimic a source of nectar. Then foraging bees were introduced to the dangers at the station such as competition from rival colonies. When foragers returned to the hive, they stopped bee’s dancing. Scientist think the behavior warns dancers of a dangerous source of nectar.
