Gallformers ID Notes
“
A large, irregularly globular, hairless, green-tan gall with slightly bumpy white spots, on the buds of Quercus alba in the spring. One dissected gall was thick-walled and contained two larval cells. The gall bears a resemblance to Andricus murtfeldtae, which also grows on buds of white-group oaks (Q stellata and others) in the spring, has more than one larval cell, and has the same size and surface appearance. However, A murtfeldtae has much more prominent projections on its surface. Observed in Virginia in April.
