Galls can be up to 8 by 12 cm. Adult wasps are among the largest cynipids, at around 5mm.
Southern Washington through Oregon and California to northern Mexico.
Host plants are white oaks.
Life Cycle
Females lay eggs on stems. After the eggs hatch, galls develop around the larvae, which grow inside the galls while feeding on the gall material. Only parthenogenetic females are known for this species.
Many other insects, especially other wasp species, are parasites, inquilines, and hyperparasites of this wasp.
