Honeybees Warn Others of Risks

On the other flower, they placed the bodies of two dead bees, so they were visible to arriving insects, but would not interfere with their foraging. They then recorded whether and how the bees performed a waggle dance on their return to other members of the hive colony.
On average, bees returning from safe flowers performed 20 to 30 times more waggle runs that bees returning from dangerous flowers.
That shows that the bees recognise that certain flowers carry a higher risk of being killed or eaten by predators, such as crab spiders or other spider species that ambush visiting bees.
