• Andricus vacciniifoliae

  Golden Oak Apple Gall Wasp, Golden Oak Apple Wasp

  Andricus vacciniifoliae is a gall-forming cynipid wasp native to the west coast of North America. The species creates distinctive stem galls on huckleberry oak (Quercus vacciniifolia) and canyon live oak (Quercus chrysolepis). The galls are colorful and fruit-like in appearance, often leading to misidentification as actual fruit. The wasp has been reclassified from Andricus to Trichoteras in some taxonomic treatments, though both names remain in use.
