RESUMO
Características morfológicas sugerem que larvas de Synoestropsis sp. (Trichoptera Hydropsychidae) são predadoras. Examinamos o conteúdo estomacal de 48 larvas de Synoestropsis sp. coletadas na época de estiagem de quatro rios de cerrado (Arraia, Cauamé, Cotingo e Ereu) do estado de Roraima para avaliar o hábito alimentar de larvas desse gênero. A alta freqüência de itens animais no conteúdo estomacal das larvas corrobora a hipótese de que esta espécie é predadora.
ABSTRACT
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.
