Wasp beating its wings-An alert signal
Raw Footage of European Paper Wasp beating its wings.
Wasps produce an "alarm pheromone" that stimulates a general state of alarm in the colony and releases aggressive behaviour towards an intruder. Rapid wing beats also function as an alarm signal stimulating other wasps to defend the nest. Please be aware that wasps sting multiple times.
