Resumo

Durante un estudio intensivo del comportamiento de una población de la damisela Calopteryx haemorrhoidalis asturica, observamos nueve eventos de depredación de machos Boyeria irene sobre hembras y machos de la damisela. Estos casos se describen junto con un caso de depredación de un macho de B. irene por la avispa invasora exótica Vespa velutina. La avispa atacaba continuamente a los machos territoriales de C. h. asturica, pero no se registró ningún caso de depredación efectiva.
