The feeding habits of 17 species of Nemouroidea stoneflies (belonging to the families Nemouridae, Leuctridae and Capniidae) from the north-western Iberian Peninsula are described and quantified by means of gut content analyses. As a whole, fungi, followed by pollen (both from angiosperm and, in a lesser degree, Pinaceae), leaf fragments (CPOM), detritus and, more punctually, lichens and animalmatter are themost common items found in their guts. Nevertheless, variations among species were observed. For a species with a flight period that extends throughout the year, Protonemura globosa, variations in the diet were noticed among seasons, with pollen being more important during the spring and summer period. Together with a few previous studies, the present one reaffirms that feeding is an important aspect of the adult life in males and females of Nemouroidea.
