Summary:
Researchers have discovered which species adult dragonflies and damselflies prey upon, as modern laboratory techniques have enabled the study of the insects' diet. In the study, prey DNA was extracted from the tiny dragonfly droppings and the researchers managed to identify dozens of prey species from the samples. The results shed light on dragonflies' position in natural food webs with an unprecedented specificity.
