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.
