For the first time water dipping behaviour of Calopteryx during threatening flight is reported. Four males of Calopteryx virgo in a small rivulet coming from a spring pool in SW France involved in threatening flights near an opponent dipped a wing into the water, producing conspicuous water rings. One male did this twice and additionally hit the water with its legs, splashing water drops forward. Possible interpretations are discussed.
