Amphibolips nubilipennis, known generally as the translucent oak gall wasp, is a species of gall wasp in the family Cynipidae. Its range includes Ontario, Quebec, and much of the eastern United States.[1] [2] Hosts include Quercus buckleyi, Quercus coccinea, Quercus falcata, Quercus ilicifolia, Quercus imbricaria, Quercus marilandica, Quercus rubra, and Quercus velutina.[3]
The translucent oak gall is induced by the sexual generation of Amphibolips nubilipennis. This gall is succulent and accumulates high concentration of malic acid causing a low pH of gall tissues. The extreme acidity of the translucent oak gall tissues has been proposed to represent a defensive strategy against parasitoid wasps.[4]
