Larvas de Synoestropsis sp. (Trichoptera: Hydropsychidae) são predadoras?

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 e 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.
