Abstract

The veracity of food webs and other trophic structures derived from empirical data sets depends ultimately on our ability to identify species diets and, thus, to classify organisms according to their major energy source or functional feeding groups. True omnivory (mixing plant and animal food) is common among terrestrial and marine arthropods, but poorly documented in freshwater systems. In a field study, we examined a guild of six large-bodied, lotic insects (Plecoptera and Trichoptera) that are generally considered to be predatory and that coexist in one stream
