The Buzz on Rough Oak Bulletgalls

Rough Oak Bulletgalls induced by the gall-wasp, Disholcaspis quercusmamma (family Cynipidae) are splitting through the bark and rising on the stems of oaks in the white oak group in southwest Ohio. The galls are most commonly found on bur (Quercus macrocarpa), white oak (Q. alba), and swamp white oak (Q. bicolor).
