Andricus quercuspetiolicola
Oak Petiole Gall Wasp
Andricus quercuspetiolicola is a species of cynipid gall wasp that induces distinctive galls on white oaks (Quercus alba). The species name reflects its biology: 'quercus' for oak and 'petiolicola' indicating its habit of forming galls on leaf petioles and midribs. Adult wasps are small and inconspicuous, while the galls they produce are the most visible sign of their presence. Like other Andricus species, this wasp has a complex life cycle typically involving alternation between sexual and asexual generations on different oak tissues, though specific details for this species remain incompletely documented.
