Morphological characteristics of the Synoestropsis sp. larvae (Trichoptera: Hydropsychidae) suggests that this species is a predator. We examined the stomach contents of 48 Synoestropsis sp. larvae collected in four savannah rivers (Arraia, Cauamé, Cotingo and Ereu) in the state of Roraima during the dry season to evaluate their feeding habits. The high frequency of animal items in the stomach content confirmed the hypothesis that this specie is a predator.
