Knowing the trophic links between species is essential to understand their functions in the ecosystem. In this work, we report the first predation record of Rhinella crucifer by the giant water bug Lethocerus grandis. Even though most Brazilian anurans preyed by giant water bugs are smaller than this insect, a larger body size of this predator together with its anesthesic saliva may provide conditions for the subjugation of larger prey.
