Trichoteras vacciniifoliae, formerly Andricus vacciniifoliae,[1] the golden oak apple wasp, is a species of gall-forming hymenopteran.

The wasp creates a stem gall[2] on host plants, namely huckleberry oaks and canyon live oaks.

[3] Andricus vacciniifoliae is native to the west coast of North America.

[4] Because of their colorful appearance and location on the plant, the galls are often mistaken for fruit.

[5] The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers.
