Washington, September 10 : Ever wondered why predatory wasps hunt free-flying bees, rather than foraging bees directly from the honeybee nest?
Well, researchers at the University of Graz, Austria, and the Royal Botanic Gardens Kew, UK, say that it is all because the shimmering—a remarkable capacity of rapid communication in giant honeybees—acts as a defensive mechanism and repels predatory hornets.
The researchers describe shimmering as a phenomenon wherein thousands of honeybees flip their abdomens upwards within a split-second to produce a Mexican Wave-like pattern across their nests.
