Victoria amazonica pests — FAQ
What is eating my victoria amazonica?
The giant Amazon water lily's massive pads are browsed by capybara and large waterfowl in the wild. In botanical garden cultivation, aphids cluster on petioles and emerging pads, while aquatic snails damage undersides. Leaf-mining flies may tunnel into pads. Its spiny underside deters many surface feeders, and vigorous tropical growth outpaces most moderate pest pressure.
