Acraspis macrocarpae, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, [2] [3] tribe Cynipini (oak gall wasps), [4] found in North America. [5] [6]

Hosts are white oaks, including bur oak and Gambel oak. [7]

Description[]

Larvae induce galls on the underside of host leaves in summer, on secondary veins. [2] [8] The detachable gall is oval in shape, color can range from white to yellowish to tan or brown. The surface is fissured into facets that end in a short, hard point, reminiscent of jewelry. [7] [9]

The conspicuous galls seen in summer and fall likely contain only female larvae of the asexual generation. Fertile, wingless female adults emerge in the fall and reproduce parthenogenetically to yield the sexual generation. [10]
