Range
Southern Washington through Oregon and California to northern Mexico.
Food
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.
Remarks
Many other insects, especially other wasp species, are parasites, inquilines, and hyperparasites of this wasp.
