Besbicus multipunctatus, formerly Cynips multipunctatus, also known as the gray midrib gall wasp, is a common species of cynipid wasp that induces galls on oak trees on the west coast of North America. [1] The wasp oviposits on the midrib of the underside of blue oak leaves. [1] The galls induced by this wasp are solid, except for the large central larval chamber, and are detachable. [1] This wasp is found primarily, but not exclusively, in California. [2]
