The effect of host plant inundation on survivorship of Symmeria paniculatas galling herbivores was investigated in Central Amazonian floodplain forest. The majority of submerged galls were alive (62% of morphospecies 1 and 70% of morphospecies 2). Survivorship was similar between submerged leaves and new leaves that were never submerged. Some submerged galls were eaten by fish. To the best of our knowledge, this is the first report of galling insect survivorship under severe flooding. RESUMO O efeito da inundação da planta hospedeira na sobrevivȩncia dos herbívoros galhadores de Symmeria paniculata foi investigado numa floresta inundável da Amazo̧nia Central. A maioria dos insetos galhadores submersos estava viva (62% para morfoespécie 1 e 70% para morfoespécie 2). A sobrevivéncia foi semelhante entre folhas submersas e folhas que nunca foram submersas. Algumas galhas submersas foram predadas por peixe. Este e o primeiro estudo que relata sobrevivȩncia de insetos galhadores à rigorosa inundação.
