Oak bullet gall wasps cause abnormal growths typically forming on branches of oak trees.
These galls, sometimes called rough bullet galls, can quickly become unsightly. They usually cause no appreciable harm to their oak hosts because they do not disrupt the vascular flow in the twigs, but Round hard galls from oak bullet gall wasps can impact growth of young oaks if the population is high enough.
Most bullet galls are more or less round-shaped and measure about 1/2″ in diameter. Colors vary from light green to reddish-green, to light brown depending on the wasp species and the age of the gall. Some bullet galls are covered in very fine, short hairs, while others are completely smooth.
